Bladder Cystectomy Increases the Risk of Vaginal Complications

In this study, the researchers included 481 women undergoing cystectomy from the Medicare Limited Data Set. Among 481 women, 37.2% were less than 70 years old. They compared the patients experiencing a vaginal complication after cystectomy to those who did not. They evaluated the demographic and biological factors that could increase the likelihood of complications and determined the time to development of complications. They used Kaplan-Meir estimates to calculate the cumulative incidence. They also used a multivariable cause-specific Cox proportional hazards model to assess the risk factors for vaginal complications.

Key findings of the study:

• Upon analysis, the researchers found that the majority 378 (79%), had bladder cancer and, 401 (83.4%) underwent an incontinent conduit or catheterizable channel diversion.
• They noted that within two years of cystectomy, 93 patients (19.5%) had one or more complications on record.
• They found that the vaginal cuff dehiscence had the highest cumulative incidence, occurring in 49 patients (10.2%).
• Over the entire study period (2011–2017), they noted that 102 women (21.2%) were diagnosed with a vaginal complication, and 27 (5.6%) received an intervention.

The authors concluded, "Among women who undergo cystectomy, vaginal complications occur at rates higher than expected with over 20% of women experiencing a complication and over a quarter of those diagnosed undergoing intervention."
