Abstract

Objective To explore influence of total mesorectal excision, radical resection and pelvic autonomic nerve preservation surgery on male sexual function and urinary function. Methods Fifty-six cases of rectal cancer patients were randomly divided into observation group and control group: the observation group underwent TME+ PANP treatment, the control group underwent conventional TME treatment.One-year postoperative survival rate, recurrence rate, and the sexual and urinary function(including erectile function and ejaculatory function)of patients were evaluated. Results No deaths occurred in both groups.Two cases of TME+ PANP group, and 1 case of TME group developed recurrence, the relapse rate of the two groups have no significant difference(P>0.05). There is no significant difference between TME+ PANP group and TME group(P>0.05)on urinary function.The postoperative ejaculation function of TME+ PANP group is better than that of of TME group(P<0.05); The postoperative erectile function of TME+ PANP group was better than that of TME group(P<0.05). Conclusion TME and PANT do not increase local recurrence rate and could reduce urinary dysfunction, sexual dysfunction and ejaculatory dysfunction rate. Key words: Total mesorectal excision; Pelvic autonomic nerve; Urination; Sexual dysfunction, physiological
