经闭孔吊带手术效果的尿动力学研究

Urodynamic Study and Outcomes After Transobturator Tape Operation

目的:分析经闭孔吊带(TOT)术前尿流率对术后排尿困难及尿潴留的影响。方法:2006年1月-2014年12月,70例患者行TOT手术,术前均行尿动力学检查(包括尿流率),术后进行尿流率检查。以术前的峰值流率(Qmax)15ml/s为界,分为低流率组22例和正常流率组48例。结果:术后尿潴留2例(2.86%),排尿困难12例(17.14%)。两组在年龄上没有显著差异。低流率组膀胱容量和最大逼尿肌压力较高。术后排尿困难情况,两组之间无显著性差异。此外,3例术后尿潴留患者术前高尿流率。结论:TOT可以有效治疗女性压力性尿失禁。低流率组术后成功率与正常流率组相当,低尿流率的压力性尿失禁患者可以安全的进行TOT治疗。

Objective： To analyze the influence of preoperative urinary flow rate on postoperative dysuria and urinary retention after the transobturator tape operation （TOT）. Methods： From 2006 to 2013,a total of 70 patients who underwent TOT. All patients were preoperatively underwent preoperative urodynamic studies including urine flow rate. Voiding difficulty, retention, Postoperative uroflowmetry were checked. Patients were divided by preoperative peak flow rate （Qmax） of 15ml/s （low flow rate group and normal flow rate group）. The low flow rate group included 22 patients and the normal flow rate group included 48 patients. Results：There were 2 cases of postoperative urinary retention （2. 86%） and 12 cases of voiding difficulty （17.14%）. Between the two groups, there were no significant differences in age. ＇The low flow rate group had higher scores for voided volume and detrusor pressure at Qmax. However, there was no significant difference in postoperative voiding difficulty between the two groups. Furthermore, three patients who experienced postoperative retention showed high flow rates preoperatively. Conclusion： TOT can effective treatment of female stress urinary incontinence. The low flow rate group the success rate and normal flow rate, low in patients with stress urinary incontinence of urine flow rate can be safe for TOT treatment.
