Independent Factors Affecting Postoperative Short-Term Urinary Continence Recovery after Robot-Assisted Radical Prostatectomy

Background. Our team had firstly applied the transvesical approach to robot-assisted radical prostatectomy (RARP) in patients afflicted with localized prostate cancer (PCa). The present study aims to present the postoperative recovery of urinary continence (UC) following the anterior, transvesical, and posterior approaches to RARP for localized PCa and evaluate the independent predictors to early UC recovery after RARP. Methods. Patients harboring localized PCa and receiving anterior, transvesical, and posterior approaches to RARP between January 2017 and June 2020 were enrolled in this analysis. Results on UC recovery were compared between these three approaches with the Kaplan–Meier method. All clinical and pathological variables were further analyzed via univariable and multivariable regression analysis to determine the independent factors contributing to short-term UC recovery after RARP. Results. A total of 135, 73, and 66 instances were included in the anterior, transvesical, and posterior groups, respectively. Over the postoperative follow-up period, both the transvesical and posterior approaches showed an advantage over the anterior approach in promoting postoperative UC recovery (both p values <0.001). Three months after surgery, 55 (40.7%), 4 (5.5%), and 5 (7.6%) patients failed to UC in the anterior, transvesical, and posterior groups, respectively. Patient age, preoperative PSA, prostate volume, biopsy Gleason score, surgical approach, extended lymph node dissection technique, nerve-sparing technique, and positive lymph node were related to UC status based on univariable analyses ( p < 0.05 ). Multivariable analysis results point patient age, prostate volume, surgical approach, and nerve-sparing technique as independent factors that affect postoperative UC recovery after RARP. Conclusions. The application of transvesical approach to RARP for localized PCa could obtain promising outcomes in terms of postoperative UC recovery. In addition, surgical strategies encompassing the nerve-sparing technique and the Retzius-sparing procedures, namely, the transvesical or posterior approach, during RARP could independently enable early achievement of postoperative continence.

Intravesical repair of vesicovaginal fistula guided by cystoscopy

Background: Vesicovaginal fistulas (VVF) are an unusual problem that may significantly affect a patient’s quality of life. The main causes for this condition are labour complications (mostly in developing countries) and pelvic surgeries (in industrialised countries). Treatment may be conservative or surgical. Regarding surgical treatment, there is still debate about the best approach and surgical technique. Objective: To demonstrate a correction of a VVF guided by cystoscopy using intravesical laparoscopic instruments. Methods: Case report and surgical video of a recurrent VVF treated with a hybrid technique involving direct transvesical insertion of 3 mm laparoscopic trocars and instruments guided by cystoscopy. As far as we know, although there are some reported techniques that use a combination of transvesical laparoscopic instruments and cystoscopy, this is the least invasive and most ergonomic technique described. Results: Two years after surgery, the patient remains asymptomatic and with no fistula recurrence. Conclusion: The transvesical approach guided by cystoscopy seems to be an effective, safe and ergonomic minimally invasive procedure for VVF repair.

Large congenital bladder diverticula in children

Objective: Large congenital bladder diverticula (LCBD), congenital bladder diverticula (CBD) larger than 2 cm diameter, is a rare anomaly. The aim of this study was to report long-term surgical and clinical outcomes of children with LCBD. Methods: Medical charts of all children who were diagnosed with LCBD at our institution between April 2005 and December 2017, with at least 2 year follow-up were retrospectively reviewed. Patients’ demographics, symptoms, operative technique, diverticulum size and localization, surgical outcomes and complications were recorded. Results: Fourteen patients with 18 LCBD, all male and age between 7 and 240 months (mean age: 53.5 months) were included in the study. Urinary tract infection was the main complaint in 10. Vesicoureteral reflux was detected in eight patients. Diverticula were 2–5.5 cm (mean 3.3 cm) in size. All diverticulectomies were performed transvesically and ureteroneocystostomy was added in 12 patients, 5 of whom were bilateral. No postoperative infection or recurrent reflux were observed. The median follow-up period was 4.5 years (2–12 years). Conclusion: Treatment of LCBD is mostly surgical and transvesical approach for diverticulectomy was found to be a safe and effective surgical procedure in long term follow-up.

Outcome of Obturator Nerve Block by Inguinal and Transvesical Approach in Transurethral Resection of Bladder Tumor

Introduction and aim of the study : Spinal anaesthesia for transurethral resection of bladder tumor (TURBT) does not prevent unintended stimulation of the obturator nerve when electro resection is performed on the lateral and Postero-lateral wall of the bladder. It results in muscle contraction of the adductor muscles of the thigh, which may lead to perforation of bladder wall with the resectoscope loop. The aim of the study was to compare the outcome of obturator nerve block by inguinal and transvesical approach. Materials and Methods: A prospective experimental study was done in the department of Urology Dhaka Medical College Hospital during the period of November 2016 to April 2018. Total 60 Patients were included for the study as per inclusion and exclusion Criteria. Patients were than allocated purposively into two groups by simple random sampling. Group A consisted of 30 patients where obturator nerve block (ONB) was done by transvesical approach and Group B also consisted of 30 patients where ONB was done by inguinal approach. Results: In the present study, the baseline characteristics of the patients in Group-A and Group-B were almost similar having no statistically significant difference. Obturator jerk more frequently occurred in group-B, in 13 (56.37%) patients following TURBT compared to Group-A, where 05(16.67%) patients developed obturator jerk. The intergroup difference was statistically significant (p<0.05). In case of 26 (86.67%) patients tumour was completely resectable in group-A, while in 21 (70.00%) patients of Group- B tumour was completely resectable. This was not a statistically significant difference (P>0.05). There was no incidence of bladder wall perforation in group-A, wherears this complication occurred in 02 (06.67%) cases of Group-B (p>0.05). Mean operative time in Group-A and group-B is 50.46 (±11.64) and 59.10 (±15.83) respectively (p<0.05). Conclusion: We conclude that transvesical approach is better in case of Jerk elimination and Less Procedure related time than inguinal approach during TURBT Bangladesh Journal of Urology, Vol. 23, No. 2, July 2020 p.118-123

Seminal Vesicle Cyst: A Rarecase Report

Seminal vesicle cysts are unusual but treatable causes of lower urinary tract symptoms.Transrectal ultrasonography is a good method for initial evaluation of seminal vesicle cysts. Endorectal magnetic resonance imaging should be reserved for the cases whose ultrasonographic results are not conclusive. Treatment should be restricted to symptomatic patients. Transvesical approach and laparoscopy in the hands of an experienced urologist are the best methods for resection of seminal vesicle cysts. In this article, a case of congenital seminal vesicle cysts is presented and the clinical symptoms, diagnosis, and management are discussed.

Iatrogenic vesicovaginal fistula repair-experience at Prince Hussein Urology and Organ Transplant Center

Background: Despite the advances in technology in urology practice, and the surgical approach in dealing with iatrogenic vesicovaginal fistula repair, the most important is to achieve continent rate with minimum morbidity.Methods: From January 2006 to December 2017, the medical records and operative notes of 52 female (mean age 37 year) who had undergone transabdominal transvesical operative repair of their vesicovaginal fistula (VVF) at this institution were reviewed retrospectively. CT urography and diagnostic cystourethroscopy were the modalities of diagnostic tools. Trans-abdominal, transvesical repair with omental flap interposition were performed within 4-6 months in all cases. Patients were evaluated at two to three weeks initially, then at three months interval and later annually.Results: In present study, the most common presentation of VVF was urine leakage through vagina. In two third of the patients the etiology was due to hysterectomy procedure, regarding the location of the fistula, 94.2% of the fistulas located high in the posterior wall of the urinary bladder (supratrigonal), with the mean size of 2.2cm (range 5-25mm). 49 patients had single fistula (94.2%). The mean operative time was 110 minutes (range 60-130 minutes) and the mean post-operative urethral catheterization was 21 days (range 17-24 days). Almost all patients were continent after a mean of five months.Conclusions: Iatrogenic VVF is one of the distressing complications of gynecological procedure; delayed transabdominal transvesical approach with omental flap interposition is associated with excellent and durable results with minor morbidity. Standardization of the technique is a key success in the outcome of the repair.
