- 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.

- 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.

Abstract
PDF
- Seminal vesicle abscess is a rare urologic disease. Herein, we report our experience of the first case of a 41-year-old male patient with neurogenic bladder who underwent successful treatment of seminal vesicle abscess with rectal fistula after rectal decompression. Only a simple insertion of the rectal tube with intravenous antibiotics was able to remove the seminal vesicle abscess with rectal fistula without any percutaneous, transvesical, or transurethral drainage of the abscess. Rectal decompression should be considered in advance as a treatment of seminal vesicle abscess with rectal fistula before performing any invasive abscess drainage or fistulectomy.

Abstract
PDF
- While endoscopic subureteral injection of bulking agents has become a first-line therapy for the treatment of vesicoureteral reflux (VUR), mainly due to its high success rates with minimal complications, polydimethylsiloxane (PDS) administration can be associated with bladder calcification in a minority of patients. A 10-year-old girl with prior history of subureteral administration of PDS as a treatment modality for bilateral VUR six years ago showed recurrent lower urinary tract symptoms, including dysuria, frequency, and urgency, for the past 6 months. She was admitted to our institution for right pyelonephritis with hydronephrosis. Radiologic examination had revealed two yellowish impacted stones attached to the previous site of PDS administration without recurrence of VUR. The stones were completely removed by cystolitholapaxy. This study suggests that such a late-complication should be considered in patients with recurrent urinary tract infection or lower urinary tract symptom despite complete disappearance of VUR by prior subureteral administration therapy.

Abstract
PDF
- Median raphe cysts of the perineum are rare congenital anomalies of the male genitalia, which form during embryological development, and can be found in the midline from the distal penis to the perineum. However, the incidence of median raphe cyst is likely under-reported and under-recognized. We report on the case of a median raphe cyst extending from the scrotum to the perineum with recurrent infection and purulent discharge in a 28-year-old man, which first developed at the age of 5 years. We believe it is important that urologists recognize median raphe cysts and have knowledge of their management in order to provide appropriate information to patients.

Abstract
PDF
- While the sustainment of percutaneous nephrostomy with regular change in chronic un-operable cases is widely performed for relief of urinary obstructions, performance of the blind procedure without fluoroscopic monitoring could result in clinical disaster. We report on a case of direct renal vein injury by mis-guidance of a nephrostomy catheter, which was successfully managed conservatively by serial venography monitoring combined with intensive conservative treatment. To the best of our knowledge, this is the first report on management of a renal vein injury during the percutaneous nephrostomy.
