- Background
Benign bladder tumors are rare disease entities, and insufficient studies have assessed their epidemiological characteristics. The authors investigated the prevalence of benign bladder tumors by retrospectively investigating pathology reports of transurethral resection of bladder tumor (TURBT) procedures over the past 20 years.
Methods
We analyzed 1,674 pathology reports of TURBT conducted in 1,160 patients from January 1, 2000, to April 30, 2022. The prevalence of benign tumors and histological classification according to the presence of primary (group 1) and recurrent (group 2) bladder lesions were retrospectively investigated.
Results
The mean age of patients was 65.2±11.5 years, and 1,284 cases (79.1%) were in men. Benign bladder tumors comprised 278 cases (248 patients) accounting for about 17.1% of the total TURBT cases (278/1,624). Furthermore, 184 patients (16.0%, 184/1,147) belonged to group 1 and 78 patients (27.4%, 78/285) belonged to group 2. Among all benign lesions that underwent TURBT, cystitis was the most common (41.0%, 114/278), and this rate was higher in group 2 (64/184 [34.8%] vs. 50/94 [53.2%], p<0.001). The prevalence of non-neoplastic lesions was higher in group 1 (44/184 [23.9] vs. 11/94 [11.7%], p<0.001). There was no difference in the prevalence of noninvasive urothelial neoplasms between the two groups (22/184 [12.0%] vs. 8/94 [8.5%], p=0.86).
Conclusions
The probability of benign lesions in TURBT was 17.1%, among which cystitis was the most common. When TURBT was performed for recurrent lesions, the frequency of benign tumors was higher than that of primary benign bladder tumors.

- Background
The principle of treatment for a vesicovaginal fistula (VVF) tract is complete removal of the fistula tract and surrounding scar tissue, followed by anastomosis without tension from surrounding healthy tissue. We present our novel two-step procedure for VVF repair.
Methods
We retrospectively analyzed 12 women, aged 14 to 67 years, who were treated between 2011 and December 2018. Conservative treatments failed, as these patients had complex VVFs. This technique consisted of two steps: first, transurethral resection of the fistula tract and surrounding scar tissue; second, transvaginal repair of the bladder mucosa, bladder muscle, and vaginal mucosa with tensionless anastomosis. If an interposition flap was needed, we used a Martius flap.
Results
The mean operation time was 186.3 minutes (range, 145–320 minutes), and the mean urethral catheter indwelling time was 10 days. Ten patients successfully underwent surgery through a transvaginal approach with no intraoperative or postoperative complications. However, one patient developed peritoneal perforation during transurethral resection of the fistula due to severe granulation tissue formation around the fistula, which prompted conversion to an abdominal approach. In two cases, we used a Martius flap because of the poor tissue condition due to previous radiation therapy and an inflammatory reaction. At a mean follow-up of 37 months (range, 16–51 months), no recurrence of VVF was observed in any patients.
Conclusions
This novel technique for transurethral VVF tract resection followed by transvaginal fistula repair was very safe and effective technique, and this straightforward technique is expected to reduce surgeons’ burden.

Abstract Prostate cancer is increasing in frequency in Korea. Among them, ductal adenocarcinoma (DCP) has a more aggressive and poor prognosis than acinar adenocarcinoma (ACP), despite its low incidence. Patients usually present with symptoms of lower urinary tract symptoms and hematuria due to increasing tumor mass within the lumen of the prostatic urethra, making diagnosis of DCP by the transrectal prostate biopsy difficult. DCP is often metastasized at the time of diagnosis. DCP is transferable to most other organs but the metastasis to the anterior urethra is rare. There is no doubt that localized DCP requires radical prostatectomy (RP) but the guidelines for adjuvant therapy after RP have not yet been established. Methods of the treatment are confounded by individual differences, and arriving at a consensus is challenging due to insufficient data. We report a case of DCP and urethral metastasis after RP, thus aiding in the determination of treatment guidelines.
