Urinary and sexual dysfunctions are among the most common complications in rectal cancer surgery. The aim of this study was to investigate the protective effect of laparoscopic functional total mesorectum excision (FTME) on urinary and sexual function in male patients with mid-low rectal cancer. This is a prospective, single-arm, multicenter, uncontrolled, clinical study in 88 eligible subjects with mid-low rectal cancer. After informed consent, eligible patients will be performed laparoscopic FTME surgery. Patients' demographic, operative detail, postoperative outcomes and follow-up will be recorded prospectively.
