ABSTRACT
Objective To study the effect of pelvic autonomic nerve preservation(PANP)on urination and sexual function in total mesorectal excision(TME). Methods Two hundred and forty cases of male rectal cancer patients,divided into the PANP who accept the pelvic autonomic nerve preservation in TME,and the control group of 120 patients who do not.The urination and sexual function were observed and compared.3-year-survival rate,local recurrence rates of the two groups were recorded. Results The urinary disorder rates,erective disorder rates and ejaculation disorder rates of PANP group were 30.8%,28.3%and 34.2%,while values of control group were 55.0%、60.0%and 62.5%.The difference between them had statistical significance(P<0.05).The 3-year-survival rate and local recurrence rate of PANP group were 9.4%and 75.0%.The 3-year-survival rate and local recurrence rate of control group were 9.0%and 65.0%.There was no significant difference between them(P>0.05). Conclusion The PANP technique in TME could improve the urinary and sexual function of male patients without affect the prognosis.
