Abstract：Objective To explore the influence of laparoscopic radical resection of rectal carcinoma with pelvic autonomic nerve preservation on patients′ urodynamic indexes. Methods Totally 80 patients with rectal carcinoma admitted to our hospital from February 2017 to May 2019 were selected as research subjects. They were divided into group A(n=40) and group B (n=40) by a random number table method. Group A adopted laparoscopic radical resection of rectal carcinoma with pelvic autonomic nerve preservation, and group B used laparoscopic radical resection of rectal carcinoma. The incidence of postoperative complications and the urodynamics indexes, ejaculation function and erectile function after operation for six months were compared between the two groups. Results There was no significant difference in the total incidence of postoperative complications between the two groups (P＞0.05). The maximum urinary flow rate(Qmax), urine output, and maximum bladder detrusor systolic pressure (Pdet Qmax) in group A were (17.60±2.19) ml/s,(296.31±34.68) ml, and (25.62±3.24) ml, respectively, which were higher than those in group B ([13.01±1.89]ml/s,[230.49±30.18]ml, [20.12±2.37]ml), respectively, and the differences were statistically significant (P＜0.05). The residual urine volume (PVR) in group A was (33.48±5.21) ml, which was lower than that of group B ([60.14±7.59]ml), and the difference was statistically significant (P＜0.05). Postoperative ejaculation function and erectile function in group A were better than those of the group B, with statistical significances (P＜0.05). Conclusion Applying laparoscopic radical resection of rectal carcinoma with pelvic autonomic nerve preservation to treat patients with rectal carcinoma can effectively improve patient′s urinary function, ejaculation function and erectile function without increasing the incidence of complications. It has high safety and is worthy of clinical promotion.
