To sling or not to sling? Impact of intraoperative sling procedures during radical prostatectomy on postoperative continence outcomes: A systematic review and meta-analysis.

This systematic review and meta-analysis investigates the efficacy of intraoperative sling procedures in reducing postprostatectomy urinary incontinence compared to having no slings.

A comprehensive search of PubMed, Medline, Embase, and the Cochrane library from inception to November 2020 was performed. Risk of bias was assessed using the Cochrane Risk of Bias tool for randomized studies and Newcastle-Ottawa Scale for nonrandomized studies. The GRADE approach was used for critical appraisal of evidences and meta-analyses were conducted using random-effects models.

Ten studies were included (n = 1,447). Quality of evidence ranged from moderate to very low. Sling procedure was generally favorable for short-term continence outcomes, although discrepancies exist due to variability in continence definition. Sling procedure resulted in reduced urinary pad weight at 1 month postoperatively (MD: 21.55; 95%CI: 12.58 to 30.52). Patient-reported questionnaires were also favorable for the sling group for up to 3 months (IPSS; (MD: 1.44; 95%CI: 0.14 to 2.74), ICIQ-SF; (MD: 2.25; 95%CI: 1.26 to 3.24), EPIC-U; (MD: 5.30; 95%CI: 1.12 to 9.39)) postoperatively. Sling procedure improved the number of continent patients at 1 month with continence definition of zero pad use/day (RR:1.41; 95%CI: 1.10 to 1.83) but not with the definition of ≤ 1pad/day. Similarly, it reduced the time to continence with the ≤ 1 pad/day definition (MD: 0.5; 95%CI: 0.1 to 0.9) but not with the zero pad/day definition.

The current literature suggests that intraoperative sling procedures during radical prostatectomy may promote early return of continence compared to having no sling, however, there are no long-term differences.
