Surgical and functional outcomes after robot-assisted radical cystectomy in female patients: a systematic review of the literature

Abstract

Aim: We aimed to review and summarize recent data on surgical and functional outcomes in women undergoing robot-assisted radical cystectomy (RARC) and urinary diversion (UD) for bladder cancer, compared with male and open counterparts.Methods: A systematic review of English-language articles published in the last 15 years was performed on PubMed/Medline database according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Outcomes of interest included peri- and post-operative surgical outcomes [operative time (OT), estimated blood loss (EBL), hospital stay (LOS), complications, and readmission], pathological outcomes [pT stage, lymph node (LN) yield, positive surgical margins (PSMs), and positive LN (pN+)], and functional outcomes [daytime and nighttime continence, sexual activity, need for clean intermittent catheterization (CIC), and quality of life (QoL) evaluation].Results: Overall, eight studies were selected collecting data from 229 female patients undergoing RARC. The median OT was 418 min (range 311-562 min) and the median EBL was 380 mL (range 100-1160 mL). OT and EBL were not significantly different comparing males and females, whereas the robotic approach was found to be significantly related with longer OT and lower EBL compared to the open procedure. The median LOS was 9.8 days (range 6.5-21 days); no significant differences in LOS were found between open RC (ORC) and RARC in female patients, as well as between RARC in women and men. The mean incidence of 30-day complications after RARC in women was 32.9%, with 12% of high-grade complications, while the 30- and 90-day readmission rates were 20.8%, and 28%, respectively. Complications and readmission comparing RARC and ORC in female patients appear to be overlapping. The mean rate of PSMs was 2.5% and the mean rate of pN+ was 12.7%; both these outcomes were similar in RARC compared with ORC. The mean number of retrieved LN was 20.6 (range 11.3-35.5). The LN yield resulted significantly influenced by the robotic approach [median 27 (range 19-41)] compared to the open one [20.5 (range 13-28)]. After 12 months, the rate of women with daytime and nighttime continence was 66.7%-90.9% and 66.7%-86.4%, respectively, while that of sexually active women ranged 66.7%-72.7%. The need for CIC ranged 12.5%-27.2%. Administering the EORTC-QLQ-C30 questionnaire after RARC and intracorporeal neobladder, the global health status/QoL and physical and emotional functioning items improved significantly over time.Conclusion: RARC and UD in female patients is a feasible procedure with surgical outcomes overlapping with those in the male patient population. Postoperative functional outcomes on continence, sexual function, and QoL are still poorly investigated, although results inherent in the nerve-sparing approach appear promising
