Current Opinions Regarding Defense Mechanisms during Urinary Tract Infection
Jung Hoon Kim, Jong Kyou Kwon, In Ho Chang
Korean J Urogenit Tract Infect Inflamm 2013;8(2):63-72.   Published online October 31, 2013
AbstractAbstract PDF
Mucosal tissues in the gastrointestinal tract are exposed to a significant number of microorganisms, many of which present a danger to the host. In contrast, the urogenital tract is colonized rather infrequently with bacterial organisms and devoid of physical barriers such as a multi-layered mucus or ciliated epithelia, thereby necessitating separate host defense mechanisms. Recurrent urinary tract infection(UTI) represents successful microbial host evasion and poses a major health problem. In recent years, considerable advances have been made in our understanding of the mechanisms underlying the immune homeostasis of the urogenital tract. The system of pathogen-recognition receptors, including the Toll-like receptors, is able to sense danger signaling and thus activate the host immune system of the genitourinary tract. Various soluble antimicrobial molecules, including iron-sequestering proteins, defensins, cathelicidin, and Tamm-Horsfall protein, have been more clearly defined. In addition, involvement of signaling mediators such as cyclic adenosine monophosphate or the circulatory hormone vasopressin in the defense of uropathogenic microbes and maintenance of mucosal integrity has been demonstrated. Beyond this, specific receptors that are hijacked by uropathogenic Escherichia coli in order to enable invasion and survival within the urogenital system, paving the way for chronic forms of UTI, have been identified. The majority of these findings offer novel avenues for conduct of basic and translational research for development of effective therapies against the diverse forms of acute and chronic UTI.

Catheter-associated Urinary Tract Infection
Seung Ok Yang
Korean J Urogenit Tract Infect Inflamm 2013;8(2):73-82.   Published online October 31, 2013
AbstractAbstract PDF
Catheter-associated urinary tract infection (CAUTI) is the most commonly occurring nosocomial infection worldwide, accounting for approximately 40% of all hospital acquired infections. A fair number of hospitalized patients undergo insertion of a urinary catheter at some point during their stay, and the use of indwelling urinary catheters appears to be increasing. Instrumentation of the urinary tract is always a high risk factor for CAUTI. A urinary catheter compromises the normal protective mechanisms of the urinary tract and enables bacterial colonization/biofilm formation on the catheter surface. Bacteriuria may progress toward CAUTI, which has been associated with increased morbidity, mortality, hospital cost, and duration of stay. Unfortunately, many physicians are not aware of appropriate indications for use of indwelling urethral catheters as well as accurate criteria for CAUTI. These conditions could result in superfluous catheterization, a potential source of CAUTI, leading to unnecessary use of antimicrobials for treatment of asymptomatic bacteriuria, resulting in emergence of resistant organisms. We discuss the overall view of CAUTI: definition, pathophysiology, pathogenesis, treatment, and prevention, mainly including descriptions associated with the indwelling urethralcatheter.

Urothelial Changes by Inflammation in Interstitial Cystitis/Painful Bladder Syndrome
Hoon Choi, Jae Hyun Bae
Korean J Urogenit Tract Infect Inflamm 2013;8(2):83-89.   Published online October 31, 2013
AbstractAbstract PDF
Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic disease. Symptoms of IC are often exacerbated by bladder filling and are associated with various urinary symptoms. IC is diagnosed by exclusion steps for differentiation from other confusable diseases. The pathophysiology and etiology of BPS/IC is not completely understood. IC is generally assumed to involve changes in the bladder wall as well as alterations in both structural abnormality of pain processing and its modulation. Alterations of the bladder wall at the molecular and structural levels in urothelium along with their adjacent structures have been observed in human patients. Bladder nerves, urothelial cells, and smooth muscles are likely to play an important role through active communication with the immune and inflammatory systems. This review provides recent information on patients with PBS/IC and their abnormalities within the bladder.

Multidrug Resistance in Neisseria gonorrhoeae
Seung Baik, Dong Hoon Lim
Korean J Urogenit Tract Infect Inflamm 2013;8(2):90-97.   Published online October 31, 2013
AbstractAbstract PDF
Gonorrhea, caused by Neisseria gonorrhoeae is the second most prevalent bacterial sexually transmitted infection. The disease causes serious reproductive complications such as pelvic inflammatory disease, ectopic pregnancy, and infertility, and can facilitate human immunodeficiency virus transmission. Numerous antimicrobial agents have been used for the treatment of gonorrhea since sulfanilamides were introduced in 1936. Unfortunately, N. gonorrhoeae readily develops resistance to antimicrobial agents. Strains with decreased susceptibility to oral third generation cephalosporin (cefixime) are currently emerging. The US Centers for Disease Control and Prevention (CDC) no longer recommends cefixime at any dose as a first-line regimen for treatment of gonococcal infections, but recommends combination therapy with ceftriaxone 250 mg intramuscularly an deither azithromycin 1 g orally as a single dose or doxycycline 100 mg orally twice daily for 7 days as the most reliably effective treatment for uncomplicated gonorrhea.

Swedish Variant of Chlamydia trachomatis in Korea
Jae Kyung Kim, Gilho Lee
Korean J Urogenit Tract Infect Inflamm 2013;8(2):98-101.   Published online October 31, 2013
AbstractAbstract PDF

Purpose: Today, many urologists use nucleic acid amplification tests (NAAT) in diagnosis of Chlamydia trachomatis infection in Korea. A new variant of C. trachomatis with a deletion in the cryptic plasmid, which cannot be detected using commercial tests targeting the deleted DNA sequences, has been found in Sweden. Therefore, the partial deletion of cryptic plasmid DNA means that the diagnostic standards cannot detect chlamydial infection any more in cases of new mutants. The mutant type has been prevalent in Sweden, however, its incidence was not high in other countries such as France, Holland, and Denmark. In or to study the existence of this mutant C. trachomatis in Korea, we developed new primer sets for detection of this mutation.

 

Materials and Methods: We collected the first voided urine from male urethritis patient from April 2012 to August 2013 (Dankook University Hospital, Cheonan, Korea). We used the 25 confirmed C. trachomatis-positive specimens by using KL1 and KL2 primers for C. trachomatis and tested the existence of mutant chlamydial infection with the newly developed primer sets.

 

Results: We could not detect any new variant in the samples.

Conclusions: Although this mutant C. trachomatis is not seen in Korea, we should watch for the occurrence of the type in the future. I would like to briefly report on implications of the surging mutant forms and how we might attain an understanding of this phenomenon.

Prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasmagenitalium, Ureaplasma urealyticum in Chronic Prostatitis Category IIIa andIIIb Patients Using Polymerase Chain Reaction
In-Chang Cho, Yoo Seok Kim, Sung Bin Kim, Soon Ki Kim, Gyeong In Lee, Seung Ki Min
Korean J Urogenit Tract Infect Inflamm 2013;8(2):102-108.   Published online October 31, 2013
AbstractAbstract PDF

Purpose: The aim of this study was to report on the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), and Ureaplasma urealyticum (UU) in patients with chronic prostatitis (CP) IIIa and CP IIIb using PCR and correlations between four microorganisms and other clinical parameters.

Materials and Methods: The medical charts of 206 Patients who visited National Police Hospital and were diagnosed with CP IIIa and CP IIIb between January 2011 and December 2012 were reviewed. We investigated white blood cell (WBC) counts on expressed prostatic secretion (EPS) samples and the frequency of four possible causative microorganisms of prostatitis, CT, NG, MG, and UU, using PCR techniques on first voided urine samples (VB1).

Results: Of 206 patients, 88 patients were CP IIIa and 118 were CP IIIb, with a mean age of 33.8±12.9 and 34.6±11.3, respectively. CT, NG, MG, and UU were detected in 13.6%, 0%, 4.5%, and 14.8% of CP IIIa patients and in 0.8%, 0%, 3.4%, and 11.9% of CP IIIb patients, respectively. Among men aged 19-30, detection of CT was significantly greater in the CP IIIa group than in the CP IIIb group (p=0.002). CT showed a positive association with EPS or the third voided urine (VB3) WBC count grade (p<0.01), however, MG and UU did not. The relationship between numbers of detected microorganisms and WBC counts was statistically insignificant.

Conclusions: In subgroup analyses, microorganisms were detected in by PCR in 29 CP IIIa patients (32.9%) and 19 CP IIIb patients (16.1%). Young aged men in the CP IIIa group showed high prevalence of CT, and patients in whom CT was detected in urine PCR had high EPS WBC counts.

Characteristics of Uropathogens in Patients with Bladder Stones
Sum Kim, Sung Dae Kim, Kyung Kgi Park, Young-Joo Kim, Hyeon Ju Kim, Jung-Sik Huh
Korean J Urogenit Tract Infect Inflamm 2013;8(2):109-113.   Published online October 31, 2013
AbstractAbstract PDF

Purpose: Bladder stones is not a rare disease, however, the number of patients with bladder stones has decreased due to improvement of nutrition, hygiene, and optimal antibiotics. Bladder stones are typically found in adults with urinary stasis, such as foreign body, benign prostate hyperplasia, spinal cord injury, and urinary tract infection, and in children with congenital genito-urinary abnormality. The aim of this study was to identify the clinical and microbiological characteristics of patients with bladder stones.

Materials and Methods: Patients who had bladder stones between March 2009 and December 2012 were retrospectively reviewed (Jeju National University Hospital, Jeju, Korea). We analyzed the presence of spinal cord injury, cancer, previous urinary tract calculi, and urinary tract infection associated with bladder stones and also investigated the largest diameter of bladder stone, and the number of bladder stones, as well as urine and blood culture.

Results: A total of 39 patients underwent cystolithotomy or cystolithotripsy. The most common presenting symptoms were voiding disturbance (n=15, 38.5%) and hematuria (n=10, 25.6%). Of these patients, 17 (43.3%) had positive growth of organisms. Of these organisms, Escherichia coli was found in five patients, Enterococcus fecalis in three patients, Pseudomonas aeruginosa in three patients, Klebsiella pneumoniae in two patients, Staphylococcus aureus in two patients, Proteus mirabilis in one patient, and Citrobacter in one patient.

Conclusions: We believe that urinary tract infection is a major risk factor in patients with bladder stones. Proper antibiotics would be required in order to reduce the risk of formation of bladder calculi. Further investigation will be needed.

Scrotal Reconstruction with Pedicled Anterolateral Thigh PerforatorFlap in Fournier's Gangrene
Heung Chan Oh, Seong Hwan Bae, Jae Woo Lee1, Joo Hyoung Kim1, Su Bong Nam1
Korean J Urogenit Tract Infect Inflamm 2013;8(2):114-120.   Published online October 31, 2013
AbstractAbstract PDF

Purpose: We have many choices of surgical methods with scrotal reconstruction after Fournier’s gangrene. From the aesthetic perspective, the reconstruction method with anterolateral thigh perforator pedicled flap is better than other options. We report our experience with postoperative results and aesthetics of the anterolateral thigh perforator pedicled flap.

Materials and Methods: From November 2011 to May 2013, 4 patients underwent anterolateral thigh perforator pedicled flaps. The authors checked the aesthetic results and occurrence of complications at follow-up exams.

Results: There was no total or partial necrosis of flap among the four patients. The only complication was wound dehiscence followed by infection that healed secondarily during the follow-up period.

Conclusions: Anterolateral thigh perforator pedicled flap is a very useful choice for surgery at the defect caused by Fournier’s gangrene because it is relatively thin, offering an excellent aesthetic result.

Case Reports
Renal Papillary Necrosis with Calyceal Rupture: Caused by AcutePyelonephritis and Analgesic Abuse
Jung-Sik Huh, Sung-Dea Kim, Kyung Kgi Park, Young-Joo Kim
Korean J Urogenit Tract Infect Inflamm 2013;8(2):121-124.   Published online October 31, 2013
AbstractAbstract PDF
Spontaneous renal rupture is a rare condition. Renal rupture most often occurs as a result of traumatic injury, a rare entity of obstructive uropathy with stones, and spontaneous causes such as malignancy. We report on a rare case of renal rupture caused by a ureter stone measuring 5 mm in size with acute pyelonephritis (APN) in a patient with renal papillary necrosis (RPN). The patient, who suffers from attacks of gouty arthritis, frequently used analgesic for pain relief. The patient was treated with temporary percutaneous drainage and antibiotics. This case demonstrates that RPN with APN can induce renal rupture even when ureter stones are small. Thus, consideration of all medical problems is important when deciding on treatment of patients with ureter stones.

Malakoplakia in the Urinary Bladder
Seung Baik, Chul Sung Kim, Dong Hoon Lim
Korean J Urogenit Tract Infect Inflamm 2013;8(2):125-128.   Published online October 31, 2013
AbstractAbstract PDF

Malakoplakia is a rare chronic granulomatous disease, which was originally described in the urinary bladder, but can involve many other organs and soft tissues. Malakoplakia is often associated with immunosuppression or immunodeficiency and is believed to be caused by an alternation in the bacterial phagocytic system. Histologically, the presence of Michaelis-Gutmann bodies is pathognomonic. We report on a case of malakoplakia of the bladder in a 62-year-old female.

Septic Pulmonary Embolism Secondary to Prostate Abscess
Keun Bai Moon, Go San Lim, Jae Seung Hwang, Chae Hong Lim, Dae Ji Kim, Jeong Hwan Son
Korean J Urogenit Tract Infect Inflamm 2013;8(2):129-132.   Published online October 31, 2013
AbstractAbstract PDF
A 30-year-old male admitted to our hospital with sudden onset shortness of breath, general weakness, dysuria, frequency, oligouria and fever. Abdominal and chest computed tomography revealed septic pulmonary embolism, multiple thrombi along right common iliac, internal iliac and femoral vein and large size prostatic abscess (right lobe>5 cm, left lobe>3.5 cm). We, therefore, diagnosed septic
pulmonary embolism secondary to prostate abscess. Abscess was drained by transurethral resection of prostate with appropriate antibiotics therapy. There were no postoperative complications with complete abscess resolution. Septic pulmonary embolism originated from urinary tract infection is rare. So we present a case report and the review of relevant literatures.
