Abstract

Purpose: To report the prevalence of the definitions used to identify post-prostatectomy incontinence (PPI) after laparoscopic radical prostatectomy (LRP), and to compare the rates of PPI over time under different criteria.

Materials and methods: In the period from January 1, 2000, until December 31, 2017, we used a recently described methodology to perform evidence acquisition called reverse systematic review (RSR). The continence definition and rates were evaluated and compared at 1, 3, 6, 12, and >18 months post-operative. Moreover, the RSR showed the "natural history" of PPI after LRP.

Results: We identified 353 review articles in the systematized search, 137 studies about PPI were selected for data collection, and finally were included 203 reports (nr) with 51.436 patients. The most used criterion of continence was No pad (nr=121; 59.6%), the second one was Safety pad (nr=57; 28.1%). A statistically significant difference between continence criteria was identified only at >18 months (p=0.044). From 2013 until the end of our analysis, the Safety pad and Others became the most reported.

Conclusion: RSR revealed the "natural history" of PPI after the LRP technique, and showed that through time the Safety pad concept was mainly used. However, paradoxically, we demonstrated that the two most utilized criteria, Safety pad and No pad, had similar PPI outcomes. Further effort should be made to standardize the PPI denomination to evaluate, compare and discuss the urinary post-operatory function.
