Objective: To examine the safety and feasibility of three-dimensional (3D) surgical planning system for guiding robot-assisted selective artery clamping partial nephrectomy (RASPN) in completely endophytic renal tumor. Methods: Clinical data of 32 patients who suffered from completely endophytic renal tumor and underwent RASPN associated with 3D surgical planning system in Department of Urology, Sun Yat-Sen University Cancer Center from November 2018 to August 2021 were analyzed retrospectively. There were 21 males and 11 females, with the age (M (IQR)] of 45.0 (17.5) years (range: 30 to 68 years). Fifteen tumors were located on the left and 17 on the right. Maximum tumor diameter, R.E.N.A.L. Score and preoperative estimated glomerular filtration rate (eGFR) were 27.5 (13.0) mm (range: 14 to 50 mm), 10.0 (1.8) (range: 7 to 11), and 105.5 (15.7) ml·min^-1·(1.73 m²)^-1 (range: 71.1 to 124.8 ml·min^-1·(1.73 m²)^-1), respectively. The 3D reconstruction before RASPN was performed in all patients to formulate surgical planning, mainly including stereo localization of renal mass, confirmation of tumor feeding artery, and injury prediction of collecting system or vessel via "2 mm distance method" defined as probable damage of renal pelvis/calyx and artery/vein when these tissues were less than 2 mm away from tumor. Results: Totally 32 patients successfully underwent RASPN guided by 3D surgical planning system, without conversion to open operation or radical nephrectomy. Rapid location of tumor and selective clamping of artery were achieved in all cases and no one encountered global ischemia, with branch occlusion time of 24.5 (15.4) min (range: 12 to 60 min) and coincidence rate of 95.0% (57/60) between planned and actual clamping vessels. The sensitivity and specificity of 2 mm distance method for predicting the injury of collecting system were 13/15 and 17/17, respectively. The operating time of 185 (48) minuetes (range: 76 to 295 minutes) and estimated blood loss of 200 (350) ml (range: 20 to 800 ml) were observed, without intraoperative transfusion case. There was one patient performed with renal vein repair. Clavien-Dindo postoperative grade Ⅱ and Ⅲa bleeding complications occurred in 2 cases, and no postoperative urinary fistula was found. The length of hospitalization was 3 (0) days (range: 2 to 10 days). The pathological diagnosis demonstrated 4 chromophobe cell carcinomas and 2 angiomyolipomas, besides 26 clear cell carcinomas including one positive surgical margin. The postoperative latest eGFR was 103.9(18.5) ml·min^-1·(1.73 m²)^-1 (range: 75.8 to 122.3 ml·min^-1·(1.73 m²)^-1) and no tumor recurrence or metastasis was detected during the follow-up time of 15.4 (13.9) months (range: 3 to 35 months). Conclusion: For RASPN in completely endophytic renal tumor, 3D surgical planning system is contributed to determining mass position, defining tumor feeding artery, and predicting collecting system/vessel injury, which benefited precise tumor resection, postoperative renal function preservation, and perioperative urinary fistula and bleeding complication decrease.

OBJECTIVE: To analyze the prognostic factors affecting the failure of transvaginal repair of vesicovaginal fistula (VVF). METHODS: A retrospective nested case-control study was conducted. A total of 15 patients who underwent unsuccessful transvaginal vesicovaginal fistula repair in the Department of Urology, Peking University First Hospital from January 2014 to December 2020 were enrolled as the case group. A total of 60 patients receiving transvaginal vesicovaginal fistula repair by the same surgeon within the same time range, were selected as the control group. The age, body mass index (BMI), etiology of vesicovaginal fistula, associated genitourinary malformation, frequency of repair, characteristics of fistula, surgical procedure, postoperative recovery and other factors were compared between the case group and the control group, and the influencing factors of failure were analyzed. RESULTS: The BMI of the case group was (26.3±3.9) kg/m², the diameter of vaginal fistula was (1.5±0.8) cm, and the operative time of transvaginal repair was (111.8±19.8) min. The proportion of the patients with genitourinary malformations was 4/15, the proportion of the patients with multiple vaginal repairs was 13/15, the proportion of the patients with concurrent ureteral reimplantation was 6/15, and the proportion of the patients with postoperative fever was 5/15. In the control group, the BMI was (23.9±3.0) kg/m², the diameter of vaginal fistula was (0.8±0.5) cm, the operative time of transvaginal repair was (99.9±19.7) min, the rate of associated genitourinary malformation was 2/60, the rate of multiple transvaginal repair was 18/60, the rate of concurrent ureteral reimplantation was 5/60, and no postoperative fever was found. Compared with the control group, the case group had higher BMI (P=0.013), bigger vaginal fistula (P=0.002), longer time of operation (P=0.027), higher proportion of genitourinary malformations (P=0.013), higher proportion of repeated transvaginal repair (P < 0.001), higher proportion of ureter reimplantation (P=0.006), and higher proportion of postoperative fever (P < 0.001). Multivariate analysis showed that fistula diameter ≥1 cm (OR=10.45, 95%CI=1.90-57.56, P=0.007) and repeated transvaginal repair (OR=16.97, 95%CI=3.17-90.91, P=0.001) were independent prognostic factors for VVF failure in transvaginal repair. CONCLUSION Fistula diameter ≥1 cm and repeated transvaginal repair are independent prognostic factors of failure in transvaginal repair.

PURPOSE: Circular stapled hemorrhoidopexy (CSH) is widely used to treat patients with grades III–IV hemorrhoids because of less pain and short hospital stay. However, this procedure is associated with some complications, such as urge to defecate, anal stenosis, staple line dehiscence, abscess and sepsis. To avoid these complications, surgeons perform a partial stapled hemorrhoidopexy (PSH). The aim of this study is to present our early experience with the PSH. METHODS: We retrospectively reviewed the medical records of 58 patients with hemorrhoids who were treated with a PSH at Busan Hang-Un Hospital from January 2016 to June 2016. A specially designed tri-window anoscope was used, and a purse string suture was made at the mucosae of the protruding hemorrhoids through the window of the anoscope. The hemorrhoidopexy was done by using a circular stapler. RESULTS: Of the 58 patients included in this study, 34 were male and 24 were female patients (mean age, 50.4 years). The mean operation time was 12.4 minutes, and the mean postoperative hospital stay was 3.8 days. Three patients experienced bleeding (5.1%) 5 urinary retention (8.6%) and 5 skin tags (8.6%). Urge to defecate, tenesmus, abscess, rectovaginal fistula, anal stricture, incontinence, and recurrence did not occur. CONCLUSION: PSH is a minimally invasive, feasible, and safe technique for treating patients with grades III–IV hemorrhoids. A PSH, instead of a CSH, can be used to treat certain patients with hemorrhoids.

Dermoid cysts are usually asymptomatic until complications occur. Spontaneous rupture of a dermoid into an adjacent organ is a rare complication and no such case has been reported in the Philippines.

A 24-year-old primipara consulted for pilimiction. Three years earlier, she had recurrent urinary tract infection and was diagnosed to have a dermoid cyst. Left untreated, the cyst grew in size and urinary symptoms worsened. Ultrasound, CT scan and subsequent laparotomy revealed that the dermoid cyst has penetrated the bladder wall resulting to fistula formation between the dermoid and the urinary bladder. Hair and sebum were seen inside the bladder. A left salpingo-oophorectomy and partial cystectomy of the urinary bladder were done.

The first locally documented case of an ovarian dermoid cyst with fistula to the bladder is presented. A review of literature is made, the predisposing factors, possible cause, diagnosis and management are discussed.

Objective: To investigate the clinical effect of modified Snodgrass surgical technique in the treatment of hypospadias. METHODS: We retrospectively analyzed the clinical data about 212 cases of hypospadias treated by urethroplasty from January 2008 to October 2016, 94 with the modified Snodgrass technique, namely with a silk line in addition to the urethral suture to make easier postoperative removal of the suture (group A), and the other 118 with the conventional Snodgrass technique (group B). The urethral suture was removed at 10 days after surgery for the patients in group A. We compared the success rate of surgery and incidence of postoperative complications between the two groups. RESULTS: Compared with group B, group A showed a significantly higher success rate of surgery (81.36% vs 91.49%, P <0.05) but lower incidence rates of postoperative incisional infection (12.71% vs 4.26%, P <0.05) and urinary fistula (16.10% vs 6.38%, P <0.05). No statistically significant difference was found in the incidence of urethral stenosis between the two groups (2.54% vs 2.13%, P >0.05). CONCLUSIONS The modified Snodgrass technique can improve the success rate of surgery and reduce the incidence rates of incisional infection and urinary fistula, which deserves wide clinical application.

Intravesical bacillus Calmette-Guérin (BCG) immunotherapy is a common treatment modality for bladder cancer after transurethral resection of a bladder tumor. This therapy is generally safe, and development of a prostatic abscess with a prostatorectal fistula after intravesical BCG immunotherapy is a very rare complication. This finding was incidentally obtained by the authors, who examined a patient with colonoscopy for evaluation of abdominal pain. The patient was successfully treated with antitubercular drugs. To the authors’ knowledge, this is the first report of a patient with a tuberculous prostatic abscess with prostatorectal fistula after BCG immunotherapy in South Korea.

ObjectiveTo compare the effect of inlaid labial mucosal graft repair (LMGR) with that of bladder mucosal graft repair (BMGR) in the treatment of complex urethral skin fistula after hypospadias repair.

METHODSThis study included 55 cases of complex urethral skin fistula following hypospadias repair. We randomly assigned them to receive inlaid LMGR (n=36) or BMGR (n=19). After surgery, we compared the incidence of complications and recurrence rate of urinary fistula between the two groups of patients.

RESULTSThe success rates of operation were 91.7% and 84.2% in the LMGR and BMGR groups, respectively, and the penile appearance was desirable in both groups. Postoperative complications included 2 cases of urinary fistula and 1 case of urethral stricture in each group. There were no statistically significant differences between the two groups in the success rate of operation (P>0.05) or the incidence rate of postoperative complications (P>0.05).

CONCLUSIONSBoth inlaid LMGR and BMGR yield satisfactory results in the treatment of complex urethral skin fistula. However, LMGR involves less injury in mucosa collection and is easier to perform and therefore deserves more clinical attention.
