Abstract
Several studies have reported high rates of urogenital dysfunction after open and laparoscopic surgery for rectal cancer. Robotic surgery has several features that could facilitate identification and preservation of autonomic nerves. This manuscript aims to summarize the literature regarding urogenital function after robotic rectal cancer surgery and focus on technical aspects of nerve-sparing total mesorectal excision. Comprehensive searches were conducted through online databases. Selection criteria included: original articles assessing urinary and sexual function after robotic surgery of males and/or females with standardized questionnaires. A total of 16 articles were included in the review. Seven of the nine cohort studies evaluating male sexual function showed earlier recovery or better outcomes in patients operated with robotic techniques. Two studies did not find any statistically significant difference. Three out of four case series found no difference in sexual function scores measured preoperatively and after 1 year. Female sexual function was assessed in seven studies: two case series show no deterioration of at 1 year. Three comparative studies showed no difference between robotic and laparoscopic groups. Two randomized control trials showed different results in terms of male and female sexual functions with better preservation at 1 year in the robotic group in one and no difference in another. Urinary functions assessed in males and/or females in the 16 studies showed no statistically significant differences at long-term follow-up. At present, there is no evidence of superiority of robotic surgery for performing nerve-sparing rectal cancer surgery.
