IMPORTANCE The proper placement of a midurethral sling (MUS) is the key factor for a successful surgical outcome. OBJECTIVE This study aimed to evaluate the relationship of perineal ultrasonographic measures of the tape location with subjective and objective outcomes after MUS surgery at midterm follow-up of women. METHODS The tape percentile (TP; total urethral length/bladder neck tape distance×100) and urethra tape distance (UTD; the shortest distance from the longitudinal smooth muscle complex of the urethra to the midpoint of the tape) were correlated with midterm surgical success. Patient satisfaction measured with the visual analog scale (VAS) was considered as the primary outcome. The presence of stress urinary incontinence on direct questioning, the Urinary Distress Inventory 6 (UDI-6) scores, findings of the cough stress test, free uroflowmetry, postvoid residual volume, and single-cycle voiding ambulatory urodynamic monitoring (AUM) were the other outcomes. RESULTS Seventy-eight women were evaluated at a mean follow-up of 4.4 ±3.3 years. Women who were highly satisfied (VAS ≥ 8) had a significantly higher TP (64.7% vs 50.8%, P < 0.001) and lower UTD (3.6 vs 4.5 mm, P = 0.018). Irritative, stress, and obstructive scores at UDI-6 increased as the tape was located closer to the bladder neck (P < 0.001, P < 0.001 and P = 0.044, respectively), and stress symptoms decreased with a tape closer to the urethra (P < 0.001). Women with detrusor overactivity at AUM were found to have a lower TP (P < 0.001). CONCLUSION The perineal ultrasonographic evaluation of tape location with UTD and TP seems to be well correlated with the women's midterm MUS surgical outcomes.

尿道中段吊带位置的超声测量与手术结果相关吗？

重要性 正确放置尿道中段吊带 (MUS) 是手术成功的关键因素。目的 本研究旨在评估女性中期随访时会阴超声检查胶带位置与 MUS 手术后主观和客观结果的关系。方法将尿道胶带百分位数（TP；总尿道长度/膀胱颈胶带距离×100）和尿道胶带距离（UTD；尿道纵向平滑肌复合体到胶带中点的最短距离）与中期手术成功相关。用视觉模拟量表（VAS）测量的患者满意度被认为是主要结果。直接询问时存在压力性尿失禁、尿窘迫量表 6 (UDI-6) 评分、咳嗽应激测试结果、自由尿流率测定、排尿后残余量和单周期排尿动态尿动力学监测 (AUM) 是其他因素结果。结果 78 名女性接受了平均 4.4 ±3.3 年随访的评估。高度满意的女性（VAS ≥ 8）的 TP 显着较高（64.7% vs 50.8%，P < 0.001），UTD 较低（3.6 mm vs 4.5 mm，P = 0.018）。UDI-6 的刺激、压力和阻塞评分随着胶带靠近膀胱颈而增加（分别为 P < 0.001、P < 0.001 和 P = 0.044），而压力症状随着胶带靠近尿道而减少（ P < 0.001）。AUM 逼尿肌过度活动的女性 TP 较低（P < 0.001）。结论 使用 UTD 和 TP 对胶带位置进行会阴超声评估似乎与女性中期 MUS 手术结果密切相关。
