Twenty-seven patients were studied after colposuspension with lateral bead-chain urethrocystography. Successful operation, compared with unsuccessful operation, repositioned the bladder neck significantly closer to the posterosuperior surface of the symphysis pubis, though not significantly higher. After successful colposuspension, the proximal urethra is exposed to compression against the symphysis pubis by the momentary descent of the pelvic viscera during physical effort. Failure of the colposuspension was usually due to an inadequate repositioning of the bladder neck.
对27例接受阴道前壁修补术并进行侧珠链尿道膀胱造影的患者进行了研究。与手术失败的患者相比，手术成功的患者膀胱颈重新定位后明显更靠近耻骨联合的后上表面，尽管抬高程度不显著。阴道前壁修补术成功后，在用力时盆腔脏器的瞬间下降会使近端尿道受到耻骨联合的压迫。阴道前壁修补术失败通常是由于膀胱颈重新定位不足。
