To assess the postoperative lower urinary tract function in patients undergoing pelvic organ prolapse surgery.
A total of 24 women with advanced anterior vaginal wall prolapse underwent transvaginal repair using a polypropylene mesh. The preoperative, 1-week and 3-month postoperative evaluations were carried out by urodynamics. Maximal flow rate detrusor pressure at maximal flow rate, voided volume and bladder contractility index were measured. A value of P < 0.05 was considered to be statistically significant.
The mean age of patients was 73.5 years (range 49-84 years). The mean postoperative maximal flow rate, voiding efficiency and bladder contractility index decreased significantly after the operation compared with the preoperative values (P < 0.05). No significant differences were observed between preoperative and 3-month postoperative parameters. Of the patients, 33.3%, 11.1% and 50% were classified as having normal/strong contractility preoperative, 1 week and 3 months, respectively. The proportion of normal/strong contractility decreased significantly after the operation, and it recovered 3 months postoperatively. The grade of obstruction did not change significantly.
Patients undergoing pelvic organ prolapse surgery present temporary impaired detrusor contractility, which improves significantly during the midterm postoperative period.
评估盆腔器官脱垂手术患者术后下尿路功能。
共有24例阴道前壁重度脱垂的女性接受了聚丙烯网片经阴道修补术。术前、术后1周及3个月通过尿动力学进行评估。测量最大尿流率、最大尿流率时逼尿肌压力、排尿量及膀胱收缩力指数。P < 0.05被认为具有统计学意义。
患者平均年龄73.5岁（范围49 - 84岁）。术后平均最大尿流率、排尿效率及膀胱收缩力指数较术前显著降低（P < 0.05）。术前与术后3个月参数之间未观察到显著差异。患者中，术前、术后1周及3个月分别有33.3%、11.1%和50%被分类为具有正常/强收缩力。术后正常/强收缩力比例显著下降，术后3个月恢复。梗阻分级无显著变化。
接受盆腔器官脱垂手术的患者存在暂时性逼尿肌收缩力受损，在术后中期显著改善。
