The effects of TME with preserving pelvic autonomic nerve on sexual and urinary function of male

Objective:To investigate the effects of total mesorectal excision(TME) with pelvic autonomic nerve preservation(PANP) on sexual and urinary function of male.Methods:One hundred and eight cases with radical resection for rectal carcinoma were divided into PANP and TME group(56 cases) plus TME group(52 cases) according to different operative techniques.Sexual dysfunction,urination disorder rates and local recurrence rates were compared.Results:Erectile dysfunction,ejaculation disorder and urination dysfunction rates of TME plus PANP group and TME group were 32.1% and 78.8%,35.7% and 78.8% and 26.8% and 82.7%,respectively,which differences had statistical significance(P0.01).The local recurrence rates of TME plus PANP group and TME were 12.5% and 11.5%,respectively,which differences had no statistical significance(P0.05).Conclusions:TME with PANP can effectively reduce the local recurrence and the sexual and urinary dysfunction rates.
