Abstract
Objective
To assess the efficacy and safety of Adjustable Transobturator Male System (ATOMS) compared to male Readjustment Mechanical External (REMEEX) system for post-prostatectomy incontinence (PPI).
Material and methods
A systematic review and meta-analysis on adjustable device ATOMS compared to male REMEEX is presented. Studies on female or neurogenic incontinence were excluded. Primary objectives were evaluation of dryness (the proportion of patients with no-pad or one safety pad/day after device adjustment) and improvement between devices. Secondary objectives were complications and explant rate. They were estimated using a random-effect model. Statistical heterogeneity among studies was assessed using Cochran’s Q test, Higgins’s I2 statistics and tau2.
Results
Combined data of 29 observational studies with 1919 patients showed an equivalent proportion of patients treated with radical prostatectomy (p = .125) and previous radiation (p = .126). Dryness rate was 69.3% for ATOMS and 53.4% for male REEMEX (p = .008). Improvement rate was 90.8% for ATOMS and 80.2% for REMEEX (p = .007). Complication rate was 18.9% for ATOMS and 35.8% for REMEEX (p = .096) and explant rate was 5.5% for ATOMS and 13.9% for REMEEX (p = .027). Significant heterogeneity was evidenced, due to absence of randomized studies, variable incontinence severity baseline, difficulties for a common reporting of complications and difference in the follow-up. Differences observed between devices remained statistically significant when only studies with silicone-covered scrotal port (SSP) ATOMS and male REMEEX system II were considered.
Conclusions
Despite the absence of direct comparison and the limitations observed ATOMS appears more effective than male REMEEX to treat PPI, and with less explant rate as reported in the literature.
