To prospectively assess the degree of urethral hypermobility in the preoperative and postoperative periods after the tension-free vaginal tape (TVT) procedure and correlate our findings with surgical outcome.
Twenty patients with stress incontinence underwent the TVT procedure. A Q-tip test was performed before the procedure and at the 3-week postoperative follow-up visit. Cure was defined as the absence of the subjective complaint of urine leakage and the absence of stress incontinence on stress testing at cystometric capacity.
Seventeen patients (85%) were cured by the TVT procedure, 2 patients (10%) were improved, and 1 patient (5%) was unchanged. The mean preoperative and postoperative Q-tip values were 42.75 degrees and 31.75 degrees, respectively. Twelve patients had a Q-tip test result of 30 degrees or greater after surgery and 11 (92%) of these 12 patients were cured by the procedure.
On the basis of these results, we propose that the cure of stress incontinence does not require the correction of proximal urethral hypermobility.
前瞻性评估无张力阴道吊带术（TVT）术前和术后尿道活动过度的程度，并将我们的研究结果与手术结果相关联。
20例压力性尿失禁患者接受了TVT手术。在手术前和术后3周随访时进行棉签试验。治愈定义为无尿漏主观主诉且在膀胱测压容量时压力测试无压力性尿失禁。
17例（85%）患者通过TVT手术治愈，2例（10%）改善，1例（5%）无变化。术前和术后棉签试验的平均角度分别为42.75度和31.75度。12例患者术后棉签试验结果为30度或更大，这12例患者中有11例（92%）通过该手术治愈。
基于这些结果，我们提出压力性尿失禁的治愈并不需要纠正近端尿道活动过度。
