在一项前瞻性研究中，105 名有压力性尿失禁症状的患者接受了视频尿动力学测试，包括静息尿道压力轮廓测定法和经阴唇超声检查。尿道压力曲线（UPP）包括最大尿道闭合压力（MUCP）、功能长度（FL）和曲线下面积（AUC）。超声参数包括尿道厚度、尿道旋转和膀胱颈下降，以及瓦氏动作时尿道内道的漏斗/开放。通过测量内道的颅腹侧位移来评估提肌收缩强度。观察到UPP数据与年龄、产次和既往手术呈负相关，这与文献数据一致。超声显示的尿道 AP 直径与 MUCP 之间存在正相关性，这与压力性失禁女性括约肌厚度或体积减少的报道一致。超声显示的过度活动与 UPP 数据无关。然而，较低的 MUCP 与膀胱颈的广泛开放相关。最后，随着 MUCP 测量值的降低，盆底功能有较差的趋势。
In a prospective study 105 patients with symptoms of stress incontinence underwent video-urodynamic testing, including resting urethral pressure profilometry and translabial ultrasound. The urethral pressure profile (UPP) included maximum urethral closure pressure (MUCP), functional length (FL) and area under the curve (AUC). Ultrasound parameters included urethral thickness, urethral rotation and bladder neck descent, as well as funneling/opening of the internal urethral meatus on Valsalva maneuver. Levator contraction strength was assessed measuring the cranioventral displacement of the internal meatus. Negative correlations between UPP data and age, parity and previous surgery were observed which were consistent with literature data. There was a positive correlation :between the urethral AP diameter on ultrasound and the MUCP, which agrees with reports showing reduced sphincter thickness or volume in stress-incontinent women. Hypermobility on ultrasound did not correlate with UPP data. However, a lower MUCP correlated with extensive opening of the bladder neck. Finally, there was a trend towards poorer pelvic floor function with lower MUCP measurements.
