Male urinary and sexual function after robotic pelvic autonomic nerve-preserving surgery for rectal cancer

摘要

BACKGROUND: Urinary and sexual dysfunction is the potential complication of rectal cancer surgery. The aim of this study was to evaluate the urinary and sexual function in male patients with robotic surgery for rectal cancer. METHODS: This prospective study included 137 of the 336 male patients who underwent surgery for rectal cancer. Urinary and male sexual function was studied by means of a questionnaire based on the International Prostatic Symptom Score and International Index of Erectile Function. All data were collected before surgery and 12 months after surgery. RESULTS: Patients who underwent robotic surgery had significantly decreased incidence of partial or complete erectile dysfunction and sexual dysfunction than patients with laparoscopic surgery. The pre- and post-operative total IPSS scores in patients with robotic surgery were significantly less than that with laparoscopic surgeries. CONCLUSIONS: Robotic surgery shows distinct advantages in protecting the pelvic autonomic nerves and relieving post-operative sexual dysfunction.
