本研究的目的是评估随意骨盆底收缩和随意骨盆底放松对静息状态下尿道闭合压力的影响。在104个连续的妇女，三个尿道压力曲线进行：标准亲。休息时，骨盆底随意收缩，骨盆底随意松弛。低压尿道定义为最大尿道闭合压≤ 20 cmH（2）O。年龄范围为24至82岁。静息时最大尿道闭合压在盆底收缩时显著增加（平均18 cmH2 O）。与第一个曲线相比，随着盆底松弛，它显著降低（平均减少量：8 cmH（2）O）。在第一个轮廓中检测到5名女性的低压尿道，在另外11名女性的骨盆底松弛。由于骨盆底活动对静息状态下尿道闭合压力有显著影响，因此尿道压力测量的科学性和临床可信度仍存在疑问。
The aim of this study was to assess the effects of voluntary pelvic floor contraction and voluntary pelvic floor relaxation on the urethral closure pressure at rest. In 104 consecutive women, three urethral pressure profiles were performed: standard pro. le at rest, with voluntary pelvic floor contraction and with voluntary pelvic floor relaxation. A low-pressure urethra was defined as a maximum urethral closure pressure of ≤ 20 cmH(2)O. The age ranged between 24 and 82 years. The maximum urethral closure pressure at rest was significantly augmented during pelvic floor contraction ( mean: 18 cmH(2)O). Compared with the first profile, it decreased significantly with pelvic floor relaxation ( mean decrement: 8 cmH(2)O). A low-pressure urethra was detected in 5 women during the first profile and in a further 11 during pelvic floor relaxation. Because of the significant influence of pelvic floor activity on the urethral closure pressure at rest, the scientific and clinical credibility of urethral pressure measurements remain questionable.
