Literature reports of preoperative and postoperative urodynamic evaluations of women with genuine stress incontinence note a lack of effect of the surgical procedure on urethral functional length the closure pressure. This report indicates a different experience. Postoperative urodynamics 4 to 12 months following retropubic urethropexy in this group of patients demonstrated consistent and significant increases in urethral functional length and closure pressure with different patient positions and bladder volumes, when compared to preoperative studies. Postoperative stress testing also became normal. This augmentation of normal urethral function is most likely due to avoidance of midline periurethral dissection, which allows the normal urethra and urethrovesical junction to augment their functional capabilities unencumbered by iatrogenic periurethral scarification.
关于真性压力性尿失禁女性患者术前和术后尿动力学评估的文献报道指出，手术操作对尿道功能长度和闭合压力没有影响。本报告显示了不同的情况。与术前研究相比，该组患者耻骨后尿道悬吊术后4至12个月的术后尿动力学检查表明，在不同的患者体位和膀胱容量下，尿道功能长度和闭合压力持续且显著增加。术后压力测试也恢复正常。正常尿道功能的这种增强很可能是由于避免了中线尿道周围剥离，这使得正常尿道和尿道膀胱交界处能够不受医源性尿道周围瘢痕形成的阻碍而增强其功能。
