Simple vs six-branches autologous suburethral sling during robot-assisted radical prostatectomy to improve early urinary continence recovery: prospective randomized study.

We have recently described the use of a retropubic suburethral autologous sling created and placed during robotic radical prostatectomy (RARP). In this study, we assess the effectiveness of newly designed six-branches compared to two-branches suburethral autologous sling in improving early urinary continence (UC) recovery. 120 patients submitted to RARP were prospectively randomized according to the intraoperative positioning of six-branches (group 1, n = 60) or two-branches autologous sling (group 2, n = 60) obtained by different configuration of a same tract of vas deferens removed. Early UC recovery was assessed at 5 (catheter removal), 10 and 30 days postoperatively through the daily number of pads used and the International Consultation on Incontinence Questionnaire-Urinary Incontinence-Short Form (ICIQ-UI-SF) score. UC was defined as the non-use of pad. Chi square test and Wilcoxon test were used to investigate UC recovery between the two groups. Moreover, post-voiding residual was evaluated in each patient at the same time. At catheter removal, UC rate was in groups 1 and 2, 60 and 35% (p = 0.02); at 10 days 70 and 46% (p = 0.03); at 30 days 87 and 70% (p = 0.04), respectively. One patient in group 1 experienced acute urinary retention at the time of catheter removal and was treated uneventfully with a further 7-day catheterization. These preliminary data indicate that newly designed six-branches suburethral autologous sling is able to increase the rate of early UC recovery compared to the two-arms sling previously described by us.
