The aim of this study was to assess the impact of body-mass index on robot-assisted laparoscopic sacrocolpopexy (RALSCP). A retrospective study was conducted on women who underwent a RALSCP. Data were collected prospectively from 17 obese and 78 non-obese patients treated between January 2008 and January 2013. Obesity was defined as a body-mass index (BMI) of ≥30 kg/m 2 . Relationships with outcome analysed using MannWhitney U-test and Fisher's exact test. The operating time was the same in both groups: 220 vs 200 min in the obese and non-obese groups, respectively (P=0.232). The median follow-up was 12 months in both non-obese and obese patients. Overall anatomic repair rate was 94.1% and 97.4% for obese and non-obese patients, respectively (P=0.95). The overall reoperation rate (including surgery for de novo urinary-stress incontinence) was 5.9% for obese vs 11.5% for non-obese patients (P=0.8). These findings suggest that RALSCP is a viable option for obese women. The complication rates and outcomes for obese women were similar to those for non-obese women.
