Abstract
Stress urinary incontinence (SUI) is a major component of the post radical prostatectomy (RP) trifecta. Surgical treatments are sub-urethral slings, artificial urinary sphincter (AUS) and adjustable peri-urethral balloons (PUB) ProACT. All options are imperfect at best and persistent SUI is challenging when AUS is not manageable. This study analyzed the cumulate experience of our 2 centers with offering PUB implantation for SUI post RP in patients with insufficient improvement from slings. This retrospective study reviewed all patients implanted with second line ProACT. The primary endpoint was continence, defined as 0 pads per day (PPD). The secondary endpoints were 50% decrease in PPD and increases in the Incontinence Quality of Life score (IQOL). Refilling and complications were reported. Between 2007 and 2016, 26 patients were implanted. Five patients have had adjuvant radiotherapy (18%). The mean follow-up was 36 months (±20; min 14-max 128). All patient presented with persistent SUI, using 2.3 PPD (±1; min 1-max 6), and only one sling was removed due to infection. After ProACT with an average 3 mL refilling (±1.2 min 2-max 6), 18 patients (66.7%) were continent. Eight of the remaining patients (29.6%) were improved; their number of PPD decreased from 2.6 to 1. The average IQOL score of those 8 patients increased by 20 points, from 53.4 up to 74.2 (P = .005). Overall 26 patients (96.3%) were improved. The remaining patient was not implanted because of an intraoperative urethral injury and is considered a failed case (3.7%). He had instead an AUS implantation. Three patients (14.8%) needed PUB replacement. The limited population of patients from both our centers who presented with persistent SUI after RP, despite sling placement, improved with PUB ProACT implantations without significant complications.
