Urogenital Tract Infection

The Necessity of Human Papillomavirus Vaccination in Men: A Narrative Review: Sooyoun Kim, Sangrak Bae; Urogenit Tract Infect 2024;19(3):51-59. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448030015

Abstract PDF PubReader ePub: Anogenital wart caused by human papillomavirus (HPV) is the most common sexually transmitted infection. High-risk strains, such as types 16 and 18, cause penile cancer in men, cervical and vulvar cancers in women, and head and neck cancers and anal cancer in both sexes. Since these malignant tumors can be prevented through vaccination, the importance of vaccination is emphasized. However, because HPV is known to cause cervical cancer, vaccination is only being administered to women. Some countries vaccinate men as well, but in South Korea, only girls are included in the National Immunization Program. However, screening for HPV in men is not possible, and the virus causes various malignant tumors, with a sharp increase in head and neck cancers, as well as a surge in genital warts in the country. In addition, HPV worsens sperm quality. Moreover, the need for vaccines is increasing as the known methods for preventing HPV-related diseases in men are decreasing and the disease burden is increasing. As cost-effectiveness studies have shown that the cost-effectiveness of vaccination is lower for men than for women, it is unlikely that male vaccination will be included in national immunization programs. Many countries overseas, especially a very small number of OECD (Organization for Economic Cooperation and Development) countries including South Korea, are implementing mandatory vaccination for women. Vaccinating men and women, would be cost-effective and efficient in achieving herd immunity. In addition to herd immunity, the inclusion of male vaccination in the National Immunization Program is imperative given the rapidly increasing incidence of diseases in men.

Trend Analysis of Sexually Transmitted Infection Treatments in Korea: Soeon Park, Byung Kyu Han, Sangrak Bae, Seung-Ju Lee, Jin Bong Choi; Urogenit Tract Infect 2024;19(2):25-30. Published online August 31, 2024; DOI: https://doi.org/10.14777/uti.2024.19.2.25

Abstract PDF PubReader ePub: Purpose: The revision of the 2023 Guidelines for the Treatment of Sexually Transmitted Infections (STIs) has been released. Hence, it is necessary to analyze the current status of STI treatments in Korea.
Materials and Methods: A questionnaire was distributed to urologists and gynecologists from December 2022 to January 2023 through an online survey program. Three hundred and forty-one urologists and 302 gynecologists responded to the questionnaire.
Results: For Neisseria gonorrhea treatment, ceftriaxone 500 mg and 100 mg of doxycycline twice daily for seven days were most preferred by urologists (22.58%). The treatment most preferred by gynecologists (15.23%) was 500 mg of ceftriaxone and 1 g of azithromycin in a single dose. Both urologists and gynecologists generally treat Chlamydia trachomatis according to the treatment guidelines. For treating Mycoplasma genitalium, 29.03% of urologists preferred administering azithro-mycin at 500 mg once daily, followed by 250 mg for four days. In contrast, 33.11% of gynecologists preferred doxycycline 100 mg twice daily for seven days.
Conclusions: Most urologists and gynecologists followed the treatments recommended in the 2nd edition of the STI treatment guidelines, revised in 2016. As many treatment regimens have changed because of the recent increase in antibiotic-resistant STIs, there is a need to encourage them to follow the new treatment guidelines.

Mechanistic Insights Into Persistent Bacterial Cystitis as a Basis for Vaccine Development: A Narrative Review: Karen Serrano-Arevalo, Manisha Naskar, Hae Woong Choi; Urogenit Tract Infect 2024;19(3):60-72. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448022011

Abstract PDF PubReader ePub: Urinary tract infections (UTIs) are primarily caused by uropathogenic Escherichia coli (UPEC), which frequently lead to recurrent infections. These bacteria utilize several strategies to establish infection in the host; in particular, virulence factors such as fimbriae and α-hemolysin facilitate persistent infection, evade host immune responses, and minimize antibiotic exposure. To date, antibiotics have been the primary treatment for UTIs. However, an increasing emphasis has been placed on the need for UTI vaccines, with mucosal vaccine products now available in several countries. Additionally, vaccines targeting intracellular UPEC, utilizing adjuvants, are currently under development. Understanding the pathogenic mechanisms of uropathogens has enabled the development of new treatment approaches, paving the way for next-generation preventive and therapeutic methods that could effectively manage recurrent UTIs in the future.

Postoperative Microscopic Pyuria and Role of Damage-Associated Molecular Pattern: A Literature Review: Min-Kyu Kim, Ki Hong Kim; Urogenit Tract Infect 2024;19(3):73-79. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448026013

Abstract PDF PubReader ePub: All patients who undergo transurethral prostate surgery exhibit pyuria and microscopic hematuria in postoperative urinalysis. Postoperative asymptomatic pyuria is associated with the inflammatory process and surface remodeling of the prostate, rather than infection. Various studies have investigated the incidence, duration, and risk factors for postoperative pyuria, noting that factors like age, surgery time, and prostate size can influence outcomes. Postoperative pyuria reflects tissue recovery and inflammation, and the use of antibiotics in asymptomatic patients may not be appropriate.

Effect of Residual Stone Fragments on Patient-Reported Quality of Life after Endoscopic Kidney Stone Surgery: Sang Hee Lee, Jun-Koo Kang, Jae-Wook Chung, Yun-Sok Ha, Jun Nyung Lee, Seock Hwan Choi, Hyun Tae Kim, Tae-Hwan Kim, Eun Sang Yoo, Tae Gyun Kwon, Bum Soo Kim; Urogenit Tract Infect 2024;19(2):31-39. Published online August 31, 2024; DOI: https://doi.org/10.14777/uti.2024.19.2.31

Abstract PDF PubReader ePub: Purpose: This study examined the effects of residual fragments (RF) on the patient-reported quality of life (QOL) after kidney stone surgery, such as retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL), using the Korean version of the Wisconsin Stone Quality of Life Questionnaire (K-WISQOL).
Materials and Methods: The medical records of 156 patients who underwent RIRS or PCNL and completed the preoperative and postoperative K-WISQOL from January 2021 to September 2023 were analyzed retrospectively. The patients were divided into RIRS and PCNL groups by the surgical method. The participants completed the K-WISQOL within four weeks before and after treatment. The patients’ baseline characteristics, surgical outcomes, and K-WISQOL scores were compared according to the presence of RF in each surgical group.
Results: Of the 156 patients, 95 underwent RIRS, and 61 underwent PCNL. In the RIRS group, the patients’ baseline characteristics and surgical outcomes were similar in the stone-free (SF) and RF subgroups. The changes in all K-WISQOL domain scores and total scores were similar in the two subgroups. In the PCNL group, the RF subgroup had a significantly higher proportion of staghorn stones, a significantly larger mean stone diameter and significantly longer operation time than those of the SF subgroup. But, the changes in all K-WISQOL domain scores and total scores were not significantly different between the two subgroups, as observed in the RIRS group.
Conclusions: This study showed that the presence of RFs after endoscopic kidney surgery did not affect the short-term patient-reported QOL regardless of the surgical methods.

Impact of the Timing of Percutaneous Nephrostomy on the Prognosis of Obstructive Urolithiasis With Sepsis: A Retrospective Cohort Study: Ji Eun Yu, Hyung Joon Kim, Hong Wook Kim, Young Seop Chang, Jin Bum Kim, Dong Hoon Koh; Urogenit Tract Infect 2024;19(3):89-96. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448018009

Abstract PDF PubReader ePub: Purpose
The aim of this study was to investigate the prognostic impact of time to percutaneous nephrostomy (PCN) insertion on obstructive ureteral stones with sepsis. Materials and Methods: Data were collected on patients who presented at our Emergency Department between 2017 and 2021 with obstructive uropathy due to urinary stones and underwent PCN insertion. Patients were stratified into 4 groups in accordance with the quick sepsis-related organ failure (qSOFA) score at presentation (<2 or ≥2) and time to PCN insertion (<4 hours or ≥4 hours) as follows: group 1, qSOFA < 2 and time to PCN insertion < 4 hours; group 2, qSOFA < 2 and time to PCN insertion ≥ 4 hours; group 3, qSOFA ≥ 2 and time to PCN insertion < 4 hours; group 4, qSOFA ≥ 2 and time to PCN insertion ≥ 4 hours. The prognostic impacts of the time to PCN insertion were compared between these groups
Results
The total cohort consisted of 96 patients, of whom 70 were classified as either group 1 or 2 (qSOFA < 2). Overall, 37 patients had a positive urine culture. The median time to PCN insertion was 218 minutes, and the median length of stay was 14 days. The hospitalization period was significantly shorter in group 3 than in group 4 (p=0.041).
Conclusions
A shorter length of stay was associated with more rapid PCN insertion in patients with obstructive uropathy and a high risk of sepsis.

Impact of Microbial Infection on Sperm Parameters of Seminal Bacteria in Asymptomatic Subfertile Males: Sae Byuk Chang, Tae Jin Kim, Tae Heon Kim, Seung-Ryeol Lee, Young Kwon Hong, Dong Soo Park, Sun-Mi Cho, Dong Hyeon Lee, Young Dong Yu; Urogenit Tract Infect 2023;18(3):82-92. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.82

Abstract PDF PubReader ePub: Purpose: This study examined the effects of asymptomatic bacteriospermia on the semen quality of subfertile males. The types of bacteria and their antibiotic susceptibility were also analyzed.
Materials and Methods: Semen was collected and analyzed from 510 subfertile males. One hundred and seventy-nine males showed bacteriospermia, while 331 males did not. The bacterial species, sperm parameters, hormone levels, underlying disease, and lifestyle patterns were compared between the two study groups.
Results: The bacteriospermic males showed significantly higher rates of leukocytospermia (p=0.001) and deoxyribonucleic acid (DNA) fragmentation than the non-bacteriospermic males. Sperm motility was significantly lower in the bacteriospermic males than in non-bacteriospermic males. The most common seminal bacterial species were Prevotella bivia (P. bivia, 41.3%) and Ureaplasma urealyticum (U. urealyticum, 13.4%). U. parvum showed the highest recurrence rates (31.8%) three months after the initial antibiotic treatment. Regarding the sperm parameters of bacteriospermic males, the sperm concentration, total motility, progressive motility, leukocytospermia, and DNA fragmentation were improved significantly after the initial antibiotics treatment. Multivariate logistic regression analyses revealed P. bivia, U. urealyticum, and U. parvum to be associated with the decreased motility and increased DNA fragmentation of spermatozoa. P. bivia was also associated with a decreased sperm concentration (p=0.002) and vitality (p=0.013).
Conclusions: Bacteriospermia decreased the sperm concentration, motility, normal morphology, and vitality. P. bivia is the most commonly observed bacteria in subfertile males. Appropriate antibiotic therapy of seminal bacteria species had a strong positive impact on improving the semen parameters.

Pelvic Pain in Men with Mycoplasma Genitalium: Yumi Seo; Urogenit Tract Infect 2024;19(1):16-23. Published online April 30, 2024; DOI: https://doi.org/10.14777/uti.2024.19.1.16

Abstract PDF PubReader ePub: Purpose: There are debates about Mycoplasma genitalium (M. genitalium) causing prostate infection and inducing pelvic pains. Consequently, M. genitalium-associated pelvic pains were characterized and their manifestation in male pelvic pain syndrome (MPPS) was evaluated through a case-control study.
Materials and Methods: The presence of M. genitalium-associated pelvic pains was examined in 113 M. genitalium-infected men, and the typical presentations of mycoplasma-associated MPPS were characterized through a case-control study involving 80 mycoplasma-infected and 234 case-matched uninfected controls. Finally, changes in symptoms following antimicrobial treatments were compared between 27 cured and 14 persistently infected cases.
Results: Pain locations from 113 men were followed as items-1a for 25.7%, 1b for 21.2%, 1c for 31%, 1d for 18.6%, 2a for 59.3%, and 2b for 23% from the Korean National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) questionnaire. In addition, the sum scores from the pain domain, voiding domain and total score were 6.68±4.75, 2.69±2.66, and 15.00±8.66, respectively. Successful antibiotic therapy significantly reduced the total score from baseline (15.148±6.798 vs. 5.357±7.025, p=0.001). From the case-control study, mycoplasma-infected men had pains more frequently during urination (1c) and on the tip of the penis (2a) (all p=0.0001) than the controls.
Conclusions: It was found that M. genitalium infection is associated with clinically significant male pelvic pains, which improved with adequate antimicrobial therapies. Urethral irritation symptoms without pyuria may be the typical characteristics of mycoplasma-associated pelvic pains in MPPS.

Outbreak of Cystoscopy-Related Urinary Tract Infections With Pseudomonas aeruginosa in South Korea, 2022: A Case Series: Beomsoo Kim, Young-Sin Choi, Jun-Koo Kang, Yun-Sok Ha, Seock Hwan Choi, Bum Soo Kim, Hyun Tae Kim, Eun Sang Yoo, Tae Gyun Kwon, Jae-Wook Chung, Tae-Hwan Kim; Urogenit Tract Infect 2024;19(3):97-103. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448028014

Abstract PDF PubReader ePub: Purpose
This study conducted an epidemiological investigation of Pseudomonas aeruginosa urinary tract infections (UTIs) following cystoscopy at Chilgok Kyungpook National University Hospital. Materials and Methods: From May 16 to July 15, 2022, among 353 patients who underwent cystoscopy, 6 patients reported febrile UTIs following cystoscopy. They were admitted to the urology department of the hospital after visiting the Emergency Department. P. aeruginosa was found in the urine cultures of 4 of the 6 hospitalized patients. During the epidemiological investigation, no changes were observed in factors such as the reprocessing procedures for endoscopic equipment. Therefore, microbiological tests were performed using environmental samples derived from the endoscopic equipment and cleaning process.
Results
P. aeruginosa was identified in a dual-enzymatic detergent (EmPower) used during the endoscope cleaning process. After changing the disinfectant and cleaning process, no further bacterial growth was observed in subsequent microbiological tests.
Conclusions
This study highlights the potential of cystoscopes to serve as reservoirs for bacteria due to inadequate cleaning during the disinfection process. To minimize the risk of infections following cystoscopy, it is important to pay close attention to the reprocessing and cleaning of cystoscopes.

Klebsiella pneumoniae-Induced Emphysematous Prostatic Abscess Accompanied by a Spinal Cord Infarction: Case Report: Seong Uk Jeh, Min Sung Choi, Chang Seok Kang, Dae Hyun Kim, Jae Hwi Choi, See Min Choi, Sung Chul Kam, Jeong Seok Hwa, Jae Seog Hyun; Urogenit Tract Infect 2024;19(3):104-108. Published online December 31, 2024; DOI: https://doi.org/10.14777/uti.2448024012

Abstract PDF PubReader ePub: Various strains can be found in emphysematous prostatic abscesses (EPAs), but the most frequent causative organism is Klebsiella pneumoniae . Hypervirulent K. pneumoniae can disseminate to distant sites by forming a muco-polysaccharide network outside the capsule. Here, we present the first case of K. pneumoniae in an EPA accompanied by a spinal cord infarction. A 65-year-old man was referred to our hospital due to sudden-onset paraplegia after a 5-day history of fever, myalgia, and voiding difficulty. Abdominal computed tomography revealed a collection of air pockets in the prostate, and diffusion-weighted magnetic resonance imaging showed high signal intensity in the thoracic spinal cord. The patient was initially treated with antibiotics and surgical drainage. On the third hospital day, therapeutic heparin was added after discussion with a neurologist. The patient had no inflammatory symptoms, experienced some improvement in paraplegia, and was discharged on the 14th hospital day. This study adhered to the case report guidelines.

Is Human Mpox a New Sexually Transmitted Infection in Korea That Should Be Monitored?: Gilho Lee; Urogenit Tract Infect 2023;18(2):35-44. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.35

Abstract PDF Supplementary Material PubReader ePub: Human monkeypox (mpox) outbreaks have been reported in more than 110 countries, with more than 86,930 confirmed cases. The World Health Organization has realized the seriousness of personal transmission and has declared a global health emergency against the infection. Traditionally, contact with infected animals in a few endemic countries has been a major transmission route of the mpox virus. On the other hand, the global mpox outbreak in 2022 has been primarily associated with sexual networks of men who have sex with men (MSM) and bisexual men exhibiting high-risk behaviors. Their common symptoms are initial fever, headache, swollen lymph nodes, and subsequent skin rashes. These presentations did not consistently occur in the 2022 outbreak. Many patients presented with skin lesions on the anogenital areas without prodromal symptoms. In addition, the atypical characteristics of the recent outbreak may result in a misdiagnosis of other skin lesions, such as chickenpox. Furthermore, infected persons are frequently co-infected with sexually transmitted infections (STIs) with similar skin lesions. The newly confirmed cases in Korea on April 2023 must have been infected through community transmission because these new patients had not traveled overseas in the past three months. Therefore, mpox is something that everybody should be concerned about in Korea. Medical practitioners must know the characteristics of the infection because patients with mpox may visit their offices with some genital lesions or other STIs. The clinical information from this paper may broaden and deepen the understanding of human mpox and curb the early transmission of the infection.

Does Music Have a Calming Effect on Pain and Anxiety in Patients Undergoing Cystoscopy?: Ye Chan Joo, Ji Eun Yu, Jae Hyun Baik, Young Seop Chang, Jin Bum Kim, Hyung Joon Kim, Dong Hoon Koh, Hong Wook Kim; Urogenit Tract Infect 2024;19(1):3-9. Published online April 30, 2024; DOI: https://doi.org/10.14777/uti.2024.19.1.3

Abstract PDF Supplementary Material PubReader ePub: Purpose: Cystoscopy is a diagnostic test performed frequently in urology outpatient clinics. Despite the large number of inspections, the associated pain, discomfort, or anxiety can markedly affect patient compliance and adherence to subsequent surveillance protocols. This study conducted a prospective, randomized study to investigate the potential efficacy of music and pyuria on pain or anxiety during outpatient cystoscopy.
Materials and Methods: In this single-institution, randomized study, the participants were assigned to a music-intervention or non-music control group. The music-intervention group underwent an identical procedure with the addition of Johann Sebastian Bach’s “Air on the G String” from Suite No. 3 in D major, BWV 1068. Urinalysis was performed to determine if pyuria affects pain during the procedure.
Results: The patient-reported outcomes, encompassing the changes in the STAI-X-1 (State-Trait Anxiety Inventory-X-1) scores, subjective levels of discomfort, embarrassment, satisfaction, and pain, were similar in the two groups. In contrast, the surgeons reported statistically significant differences in their evaluations of the same items as patient-reported outcomes of the two groups. The patient-reported pain showed no significant differences between the pyuria-negative group (0-2 and 3-5 WBC/HPF) and pyuria-positive group (>5 WBC/HPF).
Conclusions: The data from this study do not support the hypothesis that musical intervention during cystoscopy alleviates pain or anxiety to any significant extent. In addition, pyuria did not affect the patient’s reported pain. Nevertheless, a notable impact was observed in the surgeons’ assessments, suggesting that the musical accompaniment may alter the surgeons’ perception of patient pain and anxiety levels throughout the procedure.

Why Should You Care About Oral Gonorrhea and Oral Human Papillomavirus Infection?: Jae Yong Jeong, Seok Cho, Hae Do Jung; Urogenit Tract Infect 2023;18(1):20-23. Published online April 30, 2023; DOI: https://doi.org/10.14777/uti.2023.18.1.20

Abstract PDF PubReader ePub: The incidence of sexually transmitted diseases is increasing with the open-sex culture and as people are having sex at a younger age. Consequently, oral gonorrhea and oral human papillomavirus infections, which are often asymptomatic, result in a high risk of transmission. Oral gonorrhea is symptomatic in less than 20% of patients confirmed by culture for Neisseria gonorrhoeae in both men and women. Even if symptoms develop and oral gonorrhea is diagnosed and treated, the cure rate is less than 90%. Hence, oral gonorrhea can lead to antibiotic resistance to gonorrhea. Oral human papillomavirus infections have received more attention because oral human papillomavirus infections play an important role in the development of oropharyngeal cancer. On the other hand, no test for diagnosing human papillomavirus in the oral cavity has been approved by the US Food and Drug Administration. This lack of test makes it difficult to detect oral human papillomavirus infection early, which can further increase the risk of transmission of human papillomavirus infections. Preventing human papillomavirus infections is very important because surgical resection is the only treatment. Vaccination against human papillomavirus-associated oropharyngeal cancers, including tonsil cancer and base of the tongue cancer, has been reported to be effective in reducing the prevalence of oral human papillomavirus infection in middle-aged adults. Human papillomavirus vaccination is essential for protecting against oral human papillomavirus infection.

Spontaneous Bladder Perforation in a Patient with a Long-Term Intraurethral Catheter: Taegi Choi, Hyunkyung Lee, Junseok Kim, Sunghoon Lee, Younkyung Cho, Eunyoung Kang, Jinsun Kang, Sumin Lee, Eunju Na; Urogenit Tract Infect 2023;18(3):110-113. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.110

Abstract PDF PubReader ePub: Urinary catheters are commonly used to address various urinary problems. However, the catheter itself can be a cause of several complications, including catheter-associated urinary tract infections, damage to the bladder and kidneys, and, in extremely rare cases, bladder perforation. We present a case of spontaneous bladder perforation in a patient who had a long-term indwelling intraurethral catheter. The patient with prior hypoxic brain damage suddenly developed tachypnea, tachycardia, and oxygen desaturation. Computed tomography and retrograde cystography revealed an extraperitoneal bladder perforation with an intra-pelvic abscess. Antibiotics were prescribed and a urinary catheter was inserted for drainage. After 11 weeks, the abscess resolved, and the catheter was removed to enable self-voiding. The perforation was attributed to chronic inflammation and distension of the bladder wall caused by the intraurethral catheter. Given the potential complications associated with long-term urinary catheterization, the timely removal of indwelling catheters should be considered.

Risk Factors for Sepsis after Retrograde Intrarenal Surgery: Single Center Experience: Jinseok Kang, Koo Han Yoo, Taesoo Choi, Gyeong Eun Min, Dong-Gi Lee, Hyung-Lae Lee, Jeonghyouk Choi; Urogenit Tract Infect 2023;18(3):93-100. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.93

Abstract PDF PubReader ePub: Purpose: To evaluate risk factors for sepsis after retrograde intrarenal surgery for treatment of renal stones.
Materials and Methods: We analyzed the clinical data of 243 patients with kidney stones who visited our institution between April 2017 and April 2023. Age, sex, body mass index, underlying disease, location and size of stones, previous history of stones, previous history of urinary tract infections, duration of surgery, preoperative drainage, application of ureteral balloon dilation, and laboratory test results were included in the analysis.
Results: The mean age of the patients was 58.4 (±15.0) years; there were more men (53.1%) than women (46.9%). Of the 243 patients, the overall rate of sepsis was 5.8% (n=14) and the total mortality rate was 0.4% (n=1). In univariate analysis, history of urinary tract infection (p=0.019), positive preoperative urine culture test (p=0.009), operative duration of more than 90 min (p=0.004), and application of ureter balloon dilation (p=0.016) were statistically significant. In multivariate analysis, positive finding in the urine culture test performed before surgery (p=0.003), operation duration >90 min (p=0.005), and use of balloon dilation during surgery (p=0.011) were statistically significant.
Conclusions: There is a risk of progression to postoperative sepsis if bacteria are detected in the urine culture before surgery, if the operative time exceeds 90 min, or if balloon dilation is performed during surgery. Given that the probability of progression to sepsis is approximately 6%, close observation and active treatment are needed for patients with these risk factors.

Case of Life-Threatening Pneumonia during the Treatment of a Patient with Acute Bacterial Prostatitis: Kyung Kgi Park, Sung Dae Kim, Young-Joo Kim, Jung-Sik Huh; Urogenit Tract Infect 2023;18(3):114-118. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.114

Abstract PDF PubReader ePub: Acute bacterial prostatitis is an acute urinary tract infection associated with a bladder outlet obstruction or an immunosuppressed state. A 51-year-old man patient visited the hospital with fever, chills, and acute urinary retention that started the day before his visit after consuming a significant amount of alcohol. Conservative treatments, including catheterization for urinary drainage and antibiotics, were performed. On the third day of treatment for acute prostatitis, he complained of dyspnea. The level of oxygen differentiation was reduced significantly, and the tracheal insertion and ventilator were maintained after the radiological examination. The ventilator was discontinued, and the prostate abscess was operated on the eighth day of hospitalization. He was discharged without complications. This paper reports a case of life-threatening pneumonia and a prostate abscess during the treatment of a patient with acute bacterial prostatitis with a review of the relevant literature.

Xanthogranulomatous Epididymitis Unresponsive to Antibiotic Treatment: Yeasol Kwon, Jun Baek Park, Sang Hwa Lee, Seung Ki Min; Urogenit Tract Infect 2023;18(2):70-73. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.70

Abstract PDF PubReader ePub: Xanthogranulomatous epididymitis is very rare, and there are few case reports worldwide. Clinically, it is necessary to differentiate between chronic scrotal inflammatory diseases, such as tuberculous epididymitis and testicular tumors. Proteus and Escherichia coli are the pathogens that generally cause xanthogranulomatous pyelonephritis, but the pathogens of xanthogranulomatous epididymitis are unclear. This paper reports a case of a 66-year-old male with epididymitis on scrotal ultrasonography and had Pseudomonas aeruginosa detected in a culture test. An orchiectomy was performed because he did not respond to antibiotic treatment.

Fournier’s Gangrene: A 10-Year Clinical Experience at a Tertiary Academic Medical Center: Woo Seop Seong, Byeong Jin Kang, A Reum Kim, Kyung Hwan Kim, Hong Koo Ha; Urogenit Tract Infect 2023;18(2):64-69. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.64

Abstract PDF PubReader ePub: Purpose: This retrospective study examined the factors influencing clinical outcomes and mortality in patients with Fournier's Gangrene (FG). The medical history, diagnostic procedures, treatment approaches, complications, and mortality factors associated with FG were analyzed.
Materials and Methods: This study retrospectively analyzed the medical records of 40 patients with FG treated over 10 years. The collected data included the patient demographics, comorbidities, vital signs, laboratory tests, Fournier’s Gangrene Severity Index (FGSI) scores, wound swab culture results, treatment approaches, and length of hospitalization.
Results: Among the patients with FG, diabetes mellitus and hypertension were the most common comorbidities. The hemodialysis dependence has been identified as a significant risk factor of mortality. In addition, septic shock and an FGSI >9 were associated with increased mortality. Escherichia coli was the most prevalent bacterium in wound swab cultures, and the presence of antibiotic-resistant bacteria was significantly higher in the non-survivors. Treatment involved broad-spectrum antibiotics, emergency surgical debridement, and subsequent adjustments based on culture results.
Conclusions: Early diagnosis and prompt initiation of treatment are essential for improving the outcomes of patients with FG. Hemodialysis dependency, septic shock, FGSI scores, and the presence of antibiotic-resistant bacteria are important factors associated with mortality in patients with FG. Further research will be needed to validate these findings and explore adjunctive therapies to enhance the patient outcomes and improve FG management.

Impact of Antibiotics on the Efficacy of Immune Checkpoint Inhibitors in Metastatic Urothelial Carcinoma: Do Gyeong Lim, Ho Yeon Lee, Ho Seok Chung, Eu Chang Hwang, Seung Il Jung, Dong Deuk Kwon; Urogenit Tract Infect 2023;18(3):75-81. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.75

Abstract PDF PubReader ePub: Purpose: Emerging evidence has suggested that prior or concurrent antibiotic (ATB) use may be associated with a poor response to immune checkpoint inhibitors (ICIs) in patients with some solid tumors. This study examined the effects of ATB use on the oncological outcomes of patients receiving ICIs for mUC.
Materials and Methods: Patients receiving ICIs for mUC between 2018 and 2020 were assessed retrospectively. Those with over three cycles of atezolizumab or pembrolizumab were included. ATB use, defined as ≥ three days within 60 days before or three months after ICI administration, was compared between groups for oncological outcomes.
Results: Thirty-one patients were examined. The ATB-use and no-ATB-use groups consisted of 15 (48.4%) and 16 patients (51.6%), respectively. The ATB-use group showed a lower disease control rate (56.3% vs. 13.3%, p=0.023) than the no-ATB-use group. The objective response rate in the ATB-use group was lower than the no-ATB-use group, but the difference was statistically insignificant (43.7% vs. 13.3%, p=0.113). The ATB-use group had shorter progression-free survival (median three vs. six months, log-rank p=0.045) and shorter overall survival (median three vs. 14 months, log-rank p=0.023) than the no-ATB-use group. The most commonly used antibiotics were fluoroquinolones (46.7%), cephalosporins (40.0%), non-cephalosporin beta-lactams (6.7%), and nitrofurantoin (6.7%).
Conclusions: ATB may be associated with poorer oncological outcomes in patients with mUC who received ICI therapy. Hence, further research will be needed to understand the relationship between the modulation of ATB-related dysbiosis and gut microbiota composition with the oncological outcomes in patients with mUC.

Is Routine Voiding Cystourethrogram Necessary Following Endoscopic Subureteral Injection for Primary Low-Grade Vesicoureteral Reflux?: Jun-Koo Kang, Min Ji Park, Min Hyun Cho, Jun Nyung Lee; Urogenit Tract Infect 2024;19(1):10-15. Published online April 30, 2024; DOI: https://doi.org/10.14777/uti.2024.19.1.10

Abstract PDF PubReader ePub: Purpose: An endoscopic subureteral injection (EI) using a bulking agent is a highly successful surgical procedure, particularly for low-grade vesicoureteral reflux (VUR). Despite the serious adverse effects, routine voiding cystourethrogram (VCUG) to determine radiographic success after EI remains controversial. This study evaluated the necessity of routine postoperative VCUG in children with primary low-grade VUR.
Materials and Methods: From January 2016 to August 2021, children who underwent EI for primary low-grade (I-III) VUR with a history of febrile urinary tract infection (fUTI) were analyzed retrospectively. From January 2016 to July 2018, routine VCUG following EI was performed on all children. Thereafter, postoperative VCUG was performed only if indicated. Clinical success was defined as no fUTI during a 12-month follow-up, and radiographic success was defined as the disappearance of VUR on postoperative VCUG. The clinical and radiographic outcomes in both groups were compared.
Results: Thirty-six children were analyzed in this study. Three children (8.3%) experienced postoperative fUTI. In the routine group, clinical and radiographic success was observed in 16/17 (94.1%) and 15/17 (88.2%), respectively. Two children in the routine group experienced radiographic failure. Among these, one child showed clinical success, and the other underwent additional EI due to clinical failure. Of the indicated group, clinical failure was observed in 2/19 (10.5%). Of them, persistent VUR was identified in one child.
Conclusions: Clinical and radiologic success after EI for primary low-grade VUR is high, and routine VCUG for confirming radiographic success has a limited impact on the clinical course.

Giant Fibroepithelial Polyp in the Renal Pelvis to the Upper Ureter: Kyung Jin Chung; Urogenit Tract Infect 2023;18(3):119-122. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.119

Abstract PDF PubReader ePub: Benign ureteral tumors are rare owing to the predominance of malignancies in ureter tumors. Among them, fibroepithelial polyps are very rare, and giant fibroepithelial polyps are even rarer. This paper reports the author’s experience of giant fibroepithelial polyps detected incidentally. A 47-year-old woman was referred for severe right flank pain to the author’s center. A kidney computed tomogram revealed a long soft tissue lesion in the right kidney, upper polar calyx, pelvis, and whole proximal ureter with hydronephrosis. The radiologic reading was right renal pelvis urothelial cancer. Endoscopic removal was deemed impossible because the mass was filling the entire renal pelvis and upper ureter, so a nephroureterectomy was performed. After the nephroureterectomy, the pathology findings revealed a giant fibroepithelial polyp. This paper reports the treatment of giant fibroepithelial polyps of the ureter. Clinicians should consider the possibility of benign tumors and recommend a cautious approach to treatment if discovered.

Trends in Age-Specific Prevalence of Lower Urinary Tract Dysfunction: A Nationwide Population-Based Cohort Study: Young Hwan Kim, Se Hwa Hong, Tae Wook Kang, Hyun Chul Chung, Tae Hyoung Kim, Sae Chul Kim, Sang Baek Koh, Jae Hung Jung; Urogenit Tract Infect 2023;18(3):101-106. Published online December 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.3.101

Abstract PDF Supplementary Material PubReader ePub: Purpose: To elucidate the longitudinal changes in the prevalence of lower urinary tract dysfunction (LUTD) according to age over the past 10 years.
Materials and Methods: The changes in the proportion of prevalence for LUTD, including benign prostatic hyperplasia (BPH) and urinary incontinence (UI) among South Koreans from 2009 to 2018, were analyzed using the National Health Information Database established by the Korean National Health Insurance Service. All conditions were defined according to the corresponding Korean Standard Classification of Diseases-8 for diagnosis and surgical procedures and Health Insurance Review & Assessment Service codes for drugs.
Results: The 60-69, 70-79, and over 80 age groups accounted for more than 60% of the LUTD cases from 2009 to 2018, while significant increases in the crude prevalence of LUTD were observed over a 10-year period in all age groups (p for trend <0.05). In age groups over 60 years, LUTD was more prevalent in men than women, but there was no statistically significant difference in proportion (p>0.05). The changes in the prevalence and prevalence proportion exhibited similar trends in BPH, UI, and LUTD.
Conclusions: LUTD was more prevalent in the elderly aged over 60 years old than in younger adults. Therefore, this study suggests the development of nationwide healthcare policies to manage LUTD in the elderly population of South Korea, which is expected to become the world’s most aged population.

Feasibility of Anesthesia-Free Ureteroscopic Lithotripsy in Elderly Patients with Urinary Tract Infections: Duk Yoon Kim, Hyun Jin Jung, Eun Kyoung Yang, Won Yeol Cho; Urogenit Tract Infect 2023;18(2):60-63. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.60

Abstract PDF PubReader ePub: Purpose: Patients with underlying diseases, particularly in the elderly, urinary tract obstruction with a ureter stone would progress to severe conditions. Some of them have poor general conditions to endure anesthesia. Therefore, this study validated the feasibility of ureteroscopic stone removal without anesthesia for elderly patients with ureter stones who were under impending septic conditions or severe urinary tract infections.
Materials and Methods: Thirty-four patients (16 males and 18 females) were included in this study. All of them had serious problems, making it difficult to endure anesthesia. Most of them were inserted pre-operative percutaneous nephrostomy catheter, and ureteroscopic lithotripsy was performed successfully after intravenous analgesic injection (pethidine 25 mg).
Results: The mean age was 71.8±10.84 years. The locations of the stones were upper ureter in 11, mid-ureter in 6, and lower ureter in 17 cases. Urine and blood cultures identified bacteria from 17/34 patients. Escherichia coli was the most common (10/17), followed in order by Klebsiella pneumoniae and Staphylococcus epidermidis in 5 and 2 cases, respectively. Most patients had an abnormal white blood cell count (19,400±4,233.3/l) and elevated C-reactive protein levels (110.3±83.6 mg/L). No patient had to stop the operation because of intolerable pain. The mean of the visual analog pain scale was 3.2±0.86. The overall success rate was 100%.
Conclusions: The trial of ureteroscopic lithotripsy after administering analgesics could improve the condition of elderly patients whose general condition is too poor to endure anesthesia without serious complications.
