Abstract: Objective  To compare bladder function between nerve-sparing radical hysterectomy (NSRH) and radical hysterectomy (RH) for patients with uterine cervical cancer. Methods  This prospective study enrolled 55 patients with cervical cancer between May 2019 and May 2022 at the Department of Gynecological Oncology, Beijing Obstetrics and Gynecology Hospital, Capital Medical University: with 28 in the NSRH group and 27 in the AH group. Information of patients with stages ⅠB to ⅡA cervical cancer were collected according to the inclusion criteria. Demographic, surgical, and oncological data were collected. Results  The average age in the NSRH group was(51.0±7.9) years, and (46.3±8.5) years in the RH group, with significant statistical difference (P<0.05). There was no significant difference between the two groups in operation duration, blood loss, vaginal length, lymph node metastasis(P>0.05), depth of stromal invasion, or lymphovascular invasion in the postoperative pathology(P>0.05). Residual urine in NSRH group was more than that in RH group(P<0.05). However, the time to postoperative catheter removal was significantly shorter in NSRH group(P<0.05).Conclusions  NSRH can effectively promote the postoperative bladder function of patients with cervical cancer, thereby shortening the recovery time after surgery.
