To compare the perioperative complications, failure rate, operating time, and length of hospital stay associated with 2 minimally invasive suburethral slings in the management of stress urinary incontinence in women.
Women diagnosed with stress urinary incontinence were treated with tension-free vaginal tape (TVT) or transobturator tape (TOT). The participants were followed for the next 2 years, with scheduled evaluations 6 weeks, then 3, 6, 12, and 24 months after surgery.
Of the 104 participants, 55 were treated with TVT and 49 were treated with TOT. The condition was classified as "cured" in 81.8% of cases in the TVT group and 83.7% in the TOT group, and improvement occurred in 10.9% and 10.2% of cases, respectively. The mean operating time was shorter for patients treated with TOT than for those treated with TVT. There were no significant differences between the groups in terms of perioperative complications (abnormal voiding dysfunction, urinary infections, and de novo overactive bladder). The temporary and permanent urinary obstruction rates in the TVT group were approximately twice those in the TOT group.
Comparable complications and outcomes were observed with TVT and TOT. Tension-free vaginal implants are effective for the treatment of female stress urinary incontinence.
比较 2 种微创尿道下吊带术治疗女性压力性尿失禁的围手术期并发症、失败率、手术时间和住院时间。
对诊断为压力性尿失禁的女性患者采用经阴道无张力吊带术（TVT）或经闭孔吊带术（TOT）进行治疗。在接下来的 2 年内对参与者进行随访，术后 6 周、3 个月、6 个月、12 个月和 24 个月进行定期评估。
在 104 名参与者中，55 名接受了 TVT 治疗，49 名接受了 TOT 治疗。在 TVT 组中，81.8%的病例被分类为“治愈”，83.7%的病例在 TOT 组中被分类为“治愈”，分别有 10.9%和 10.2%的病例得到改善。接受 TOT 治疗的患者的手术时间平均比接受 TVT 治疗的患者短。两组在围手术期并发症（排尿功能异常、尿路感染和新发膀胱过度活动症）方面无显著差异。TVT 组的暂时性和永久性尿梗阻发生率约为 TOT 组的两倍。
TVT 和 TOT 的并发症和结果相似。经阴道无张力植入物是治疗女性压力性尿失禁的有效方法。
