Abstract

Objective: To demonstrate the feasibility of robot-assisted vesicourethral reconstruction. Vesicourethral anastomotic stricture following radical prostatectomy is a real challenge for reconstructive surgery when facing several endoscopic management failures., Material and Methods: This is a case series of robot-assisted vesicourethral reconstruction for anastomotic stricture failing endoscopic management. The procedure was performed with an extraperitoneal approach. The fibrotic anastomotic region was resected and a new vesicourethral running suture was performed with well-vascularized tissue. Bladder catheter was removed after 7 days., Results: Six procedures were performed from April 2013 to May 2018 at our department. One patient had a robot-assisted radical prostatectomy at our department; the 5 others were referred from other institutions after receiving open prostatectomies. Three patients had salvage radiation therapy before reconstruction. Mean age was of 73.8 years (68-82). There was no peroperative complication. Mean operative time was of 108 minutes (60-180)], with a mean estimated blood loss of 130 mL (50-300). After surgery, 3 patients presented recurrences managed endoscopically without recurrence after 3, 5, and 11 months. Three patients presented incontinence treated with artificial sphincter implantation. One patient had no residual symptom after 5 years of follow-up., Conclusions: Robot-assisted vesicourethral reconstruction is a safe procedure. It is an option to consider when facing recurring anastomotic stricture following radical prostatectomy. It is an alternative to the perineal approach and an option before urinary diversion. Patients should be informed of the risks of incontinence and recurrence before surgery especially if they had radiation therapy., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Abstract

Objective: To study the impact of changing the technique of radical prostatectomy [pure laparoscopic radical (PR-Lap) to robot-assisted radical prostatectomy (RP-Rob)] on the rate of secondary procedures for urinary incontinence (UI) and erectile dysfunction (ED)., Material: Retrospective study evaluating the number and type of surgical procedures for post-RP UI and DE between 2008 and 2015, according to the technique of (RP-Lap or RP-Rob)., Results: Between 2008 et 2015, 2046 RP were performed in our department including 372 RP-Lap and 1674 RP-Rob. Among these patients, 84 (4%) had a surgical procedure for post-RP UI (18 AMS800, 9 balloons Pro-Act, and 57 male slings) and 15 (0.7%) had implantation of penile prosthesis for post-RP ED; 16 (0.7%) patients had both procedures. The mean delay between RP and UI surgery decrease from 3.2 years in 2008 to 1 year in 2015 and remain stable for penile prosthesis implantation (mean delay: 3.4 years). The overall rates of secondary procedures for UI and DE remained stable and below 5% and 1.7%, respectively, even during the transition period. For each year of PR studied, the rates of secondary procedure were higher in the RP-Lap group., Conclusion: Changing the technique of RP from RP-Lap to PR-Rob has a favorable impact on the rate of secondary procedures for UI and ED from the outset., (Copyright © 2018 Elsevier Masson SAS.

Abstract

We recently reported stage I of a phase 1/2 clinical trial of cell therapy to treat postradical prostatectomy erectile dysfunction (INSTIN, INtra-cavernous STem-cell INjection clinical trial, NCT01089387). In this first stage, four doses of intracavernous autologous bone marrow mononuclear cells (BM-MNCs) were tested in 12 patients. Here, we report the results of stage II, in which six additional patients received the optimal dose identified in stage I (10 9 BM-MNCs), and the long-term results in the 12 patients included in stage I. The objectives were to assess the safety and efficacy of this new treatment. In stage II, no patients had side effects, and the erectile function improvements were similar to those seen in stage I: after 6 months, significant improvements versus baseline were noted in International Index of Erectile Function-15 intercourse satisfaction (7.8±3.1 vs 2.2±3.4, p=0.033) and erectile function (18±8.3 vs 3.7±4.1, p=0.035) domains. In stage I patients, after a mean follow-up of 62.1±11.7 mo, there were no prostate cancer recurrences, and erectile function scores were somewhat lower compared with the 1-yr time point. These findings suggest that intracavernous BM-MNC injections are safe and improve erectile function. The decline in erectile function over time suggests a need for assessing repeated injections., Patient Summary: We report a phase 1/2 pilot clinical trial of cell therapy consisting in intracavernous injection of bone marrow mononuclear cells to treat postradical prostatectomy erectile dysfunction. Erectile function was improved after 6 mo in the patients given 1×10 9 cells. No serious side effects (life threatening or requiring hospitalisation) occurred after a mean follow-up of 62.1 mo in the first 12 patients., (Copyright © 2017 European Association of Urology.
