Abstract：【Objective】 To explore the effects of preserving partial Denonvilliers' fascia during laparoscopic total mesorectal excision (TME) on postoperative complications and urinary function in male patients with rectal cancer. 【Methods】 A total of 100 male patients with middle and low rectal cancer admitted to our hospital from December 2021 to December 2023 were selected and divided into the control group and the observation group by random number table method, with 50 cases in each group. The control group underwent TME without preserving Denonvilliers' fascia, while the observation group underwent TME with partial Denonvilliers' fascia preserved. All patients were followed up for 1 year after operation. The operative indicators, postoperative urinary function, urodynamic parameters, postoperative erectile function, complications and prognosis were compared between the two groups. 【Results】 There were no significant differences in operation time, intraoperative blood loss and postoperative first exhaust time between the two groups (P>0.05). The incidence of postoperative urinary dysfunction in the observation group was 10.00% (5/50), which was lower than 28.00% (14/50) in the control group (χ2=5.263, P<0.05). One month after surgery, the maximum urinary flow rate, maximum urethral pressure and maximum detrusor systolic pressure in the control group were lower than those before operation; the above indicators in the observation group were higher than those in the control group (all P<0.05). There were no significant differences in the above urodynamic indicators between preoperation and 1 month after operation in the observation group (P>0.05). The postoperative incidence of erectile dysfunction (ED) in the observation group was 8.00% (4/50), lower than 28.00% (14/50) in the control group (χ2=6.775, P<0.05). The total incidence of postoperative complications was 10.00% (5/50) in the observation group and 12.00% (6/50) in the control group, with no significant difference (χ2=0.102, P>0.05). There was no significant difference in overall survival rate between the two groups (P=0.714). 【Conclusion】 For male rectal cancer patients undergoing TME, the short-term efficacy and safety are comparable between non-preservation and partial preservation of Denonvilliers' fascia. However, partial preservation of Denonvilliers' fascia can significantly improve patients' urinary and erectile function.
