To determine whether the position of the tension-free vaginal tape (TVT) has an effect on postoperative flow rates and voiding function in women successfully cured of urodynamic stress incontinence.
Postoperatively 72 women who had undergone TVT surgery had a transperineal ultrasound examination to assess the position of the TVT on the urethra. The tape was categorized as proximal, mid or distal urethral. The effect on voiding was assessed using the maximum flow rate (MFR) centiles corrected for voided volume and detrusor pressure at maximum flow.
Forty-six women had distal tapes and 26 mid-urethral tapes. A tape lying on the mid urethra was associated with a fall in MFR centile (P = 0.04) while a tape lying on the distal urethra did not cause a fall in the MFR centile (P = 0.52). There was no significant change in the detrusor pressure at maximum flow between mid and distally placed tapes.
Distally placed tapes cause less alteration in flow rates than do mid-urethrally placed tapes. This may be beneficial in certain patient groups.
确定经阴道无张力吊带（TVT）的位置是否会影响成功治愈压力性尿失禁的女性患者术后流量率和排尿功能。
术后 72 名接受 TVT 手术的女性患者进行经会阴超声检查，以评估 TVT 在尿道上的位置。将吊带分为近端、中段或远端尿道。使用校正了排空量和最大流量时逼尿肌压力的最大流量百分位数（MFR）评估对排尿的影响。
46 名女性的吊带位于远端，26 名女性的吊带位于中段尿道。位于中段尿道的吊带与 MFR 百分位数下降相关（P = 0.04），而位于远端尿道的吊带不会导致 MFR 百分位数下降（P = 0.52）。位于中段和远端的吊带之间最大流量时逼尿肌压力没有显著变化。
与位于中段尿道的吊带相比，位于远端尿道的吊带对流量率的改变较小。这在某些患者群体中可能是有益的。
