Nerve Sparing, Robot-Assisted Radical Cystectomy with Intracorporeal Bladder Substitution in the Male.

PURPOSE: We provide a step-by-step description of our technique of nerve and seminal vesicle sparing robot-assisted radical cystectomy with an orthotopic neobladder. We also present preliminary oncologic and functional outcomes. MATERIALS AND METHODS: Nerve and seminal vesicle sparing robot-assisted radical cystectomy with a modified Y-shaped orthotopic neobladder was performed by the same surgeon in 40 men with clinically localized bladder cancer from January 2011 to September 2014. Operative, perioperative and pathological data as well as continence and erectile function outcomes are presented. RESULTS: Median followup was 26.5 months (range 8 to 52). A soft tissue positive surgical margin was found in a patient with pT3a disease. A global rate of 30% early and 32.5% late complications was observed. However, the grade III or higher complication rate was low in both settings at 2.5% and 5%, respectively. There was 1 cancer related death 23 months after surgery. Of the 40 patients 30 (75%) gained daytime continence (0 pad) within 1 month postoperatively. The 12-month nocturnal continence rate was 72.5% (29 of 40 patients). Mean preoperative IIEF-6 (International Index of Erectile Function-6) score was 24.4. Erectile function returned to normal, defined as an IIEF-6 score greater than 17, in 31 of 40 patients (77.5%) within 3 months while 29 of 40 patients (72.5%) returned to the preoperative IIEF-6 score within 12 months. CONCLUSIONS: In the hands of an experienced surgeon nerve and seminal vesicle sparing robot-assisted radical cystectomy with intracorporeal reconstruction of the neobladder seems feasible and safe. It provides short-term oncologic efficacy and promising functional outcomes. Yet comparative, long-term followup studies with standard open cystectomy are required.

Robot-assisted laparoscopic radical prostatectomy with intrafascial dissection of the neurovascular bundles and preservation of the pubovesical complex: a step-by-step description of the technique.

The preservation of sexual potency after radical prostatectomy has always been the topic of much anxiety and debate. While cancer control and urinary continence are of supreme importance, the preservation of sexual function completes the trifecta that both patient and surgeon strive to achieve. The introduction of robotic assistance to modern laparoscopic surgery has provided many advantages, the two greatest being improved three-dimensional magnified vision and wristed instrumentation. These technical enhancements provide the surgeon with improved surgical tools that have the potential to facilitate a more precise surgical approach. One of the potential advantages during robot-assisted laparoscopic prostatectomy (RALP) is improving visualization, control, and dissection of the neurovascular bundle (NVB). With this article, we provide the description of our current technique of intrafascial, tension and energy-free dissection of the NVB during RALP, aiming to maximize the preservation of the periprostatic neuronal network and improve erectile function outcomes. A step-by-step description of the preservation of the pubovesical complex is also provided.
