Abstract

OBJECTIVE: To evaluate the incidence of voiding dysfunction (VD) after surgery for deep infiltrating endometriosis with colorectal involvement and compare outcomes between conventional laparoscopy (CL) and robotic-assisted laparoscopic surgery (RALS). DATA SOURCES: A systematic review and meta-analysis were conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed, Embase, the Cochrane Library, and Web of Science. METHODS OF STUDY SELECTION: Eligible studies included prospective, retrospective, or randomized trials reporting VD after RALS for colorectal endometriosis. VD was defined according to reported criteria, including need for intermittent self-catheterization, subjective dysuria, or a postoperative residual bladder volume of >100 mL. Relative risks (RRs) with 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed using the I2 statistic. TABULATION, INTEGRATION, AND RESULTS: Eleven studies met the inclusion criteria for the qualitative synthesis and 10 for the meta-analysis, comprising 728 patients (225 CL; 503 RALS). Overall, VD was observed in 52 patients (7.1%). VD was less frequent after RALS than CL (4.4% vs 13.3%; RR, 0.33; 95% CI, 0.19-0.56; p 1 month) was evaluable in 458 patients and occurred in 7.6%. Persistent VD was reduced after RALS (5.2% vs 10.2%; RR, 0.50; 95% CI, 0.26-0.99; p = .041; I2 = 60.1%). CONCLUSION: This meta-analysis demonstrates that RALS surgery for colorectal endometriosis was associated with a lower risk of both immediate and persistent VD compared with CL. These findings support the preferential consideration of RALS in patients requiring deep infiltrating endometriosis surgery with a high VD risk.
