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.

Exploring National Trends in Bladder-Related Urological Procedures: A Nationwide Population-Based Cohort Study: Hyosang Kwon, Wonjong Yang, Sangyong Park, Heesub Lee, Jong Keun Kim, Jun Hyun Han; Urogenit Tract Infect 2023;18(2):50-59. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.50

Abstract PDF PubReader ePub: Purpose: This study examined the epidemiological trends of bladder-related urological procedures in South Korea from 2009 to 2021.
Materials and Methods: The data were obtained from the Health Insurance Review and Assessment Service (HIRA) database, encompassing various bladder-related urological procedures. The frequencies and trends were analyzed using statistical methods.
Results: Uroflowmetry, cystoscopy, prostate biopsy, and urethral dilation showed a positive trend, while prostate massage exhibited a negative trend. The 72-hour voiding function test, which started in 2017, also demonstrated a positive trend in frequency. A urodynamic study and mid-urethral sling operation exhibited an overall decreasing trend. Bladder-indwelling catheter, Nelaton catheterization, and cystostomy catheter change showed increasing trends, while suprapubic cystostomy showed a decreasing trend.
Conclusions: This 12-year analysis provided valuable insights into the epidemiological patterns and utilization of bladder-related urological procedures in South Korea. These trends highlight the evolving landscape of diagnostic and therapeutic approaches in bladder-related conditions and the importance of interdisciplinary collaboration between urology and other medical departments. The results highlight the need for optimizing catheter-related care protocols, resource allocation, and continued monitoring of practices across healthcare settings.

Efficacy and Tolerability of Solifenacin Fumarate with Overactive Bladder Patients: A Multicenter Observational Study: Jae Hun Shim, Se Young Choi, Joon Hee Gook, Yong-June Kim, Woo Heon Cha, Dae Hee Kim, Kyeong Hee Kim, Young Woong Park, Jin Mo Um, Il Sung Lim, Kyung Keun Seo, Kyu Seon Cho, Young Jae Lee, Mi-Kyung Lee, Tae-Hyoung Kim; Urogenit Tract Infect 2021;16(1):8-15. Published online April 30, 2021; DOI: https://doi.org/10.14777/uti.2021.16.1.8

Abstract PDF PubReader ePub: Purpose: Overactive bladder (OAB) is characterized by a series of highly prevalent symptoms among older adults. This study used the Overactive Bladder Symptom Score (OABSS) and Patient Perception of Bladder Condition (PPBC) tools to evaluate the efficacy and stability of solifenacin fumarate in the treatment of OAB.
Materials and Methods: This was a prospective, multicenter, single-arm, 12-week study that enrolled 163 OAB patients. The patients received 5 mg/day of solifenacin fumarate. The changes in the OABSS, symptoms, and PPBC scores were evaluated at 0, 4, and 12 weeks. Subgroup analysis of the OABSS and PPBC scores based on sex, diabetes mellitus (DM) status, and body mass index (BMI) were also evaluated.
Results: At the baseline (week 0), the mean OABSS for all patients was 8.45±2.38 (p=0.199). Subsequently, the mean OABSS declined to 5.41±2.69 (p=0.255) at four weeks and 4.21±2.61 (p=0.240) at 12 weeks. The OABSS subscore and PPBC score decreased significantly during the study (p<0.01). After cases were stratified according to sex, DM status, and BMI, the mean OABSS (mean and subscore) and PPBC score at four and 12 weeks were also improved significantly relative to the baseline scores (both p<0.05). The overall incidence of adverse events was 7.36% (12 cases), and three patients (1.82%) permanently discontinued solifenacin fumarate because of the adverse events.
Conclusions: Solifenacin fumarate is a safe and effective treatment alternative for relieving OAB symptoms, considering the balance between the efficacy, patientsʼ well-being, and tolerability.

Von Brunn’s Nest in an Incidental Bladder Mass Found during Holmium Laser Enucleation of the Prostate: Seungsoo Lee; Urogenit Tract Infect 2020;15(1):13-15. Published online April 30, 2020; DOI: https://doi.org/10.14777/uti.2020.15.1.13

Abstract PDF PubReader ePub: A 62-year-old male with benign prostatic hyperplasia underwent holmium laser enucleation of the prostate. During surgery, a small nodular mass was found incidentally in the trigone of the bladder. The lesion was removed completely by a transurethral resection with a bipolar device. A pathology examination of the lesion indicated von Brunn’s nests.
