这段视频将3D高分辨率测压(HRM)系统引入到泌尿外科领域。我们演示了如何使用该测量系统获取和解释动态尿路压力，并将其用于评估手术前后的女性。3D HRM导管的长度为12 F，其长度为11 cm的压力传感器具有8个周向分布的压力敏感段，这些压力敏感段收集和传输个体压力测量数据，以构建3D压力图。在这段视频中，我们演示了3D HRM测量系统的输出显示。显示了一名患有压力性尿失禁(SUI)的女性和一名有压力性尿失禁病史的女性的压力输出图，她成功地接受了中段尿路吊带置入术。我们还总结了44名女性的3D压力测量模式，这些女性接受了压力测量，以定性地评估尿路的3D压力分布，以努力更好地了解盆底和尿道括约肌的生理学。先进的HRM技术测量咳嗽和劳损条件下的尿路压力，而不使用撤药技术，为了解可控和大小便失禁女性以及手术后的可控机制提供了新的见解。
This video introduces a 3D high-resolution manometry (HRM) system to the field of urogynecology. We demonstrate how to obtain and interpret dynamic urethral pressures with this measurement system and use it to evaluate pre- and postoperative women.The 3D HRM catheter is 12 F; 11 cm of its length has pressure sensors with eight circumferentially distributed pressure-sensitive segments that collect and transmit individual pressure measurements to construct a 3D pressure map. In this video, we demonstrate the output display of the 3D HRM measurement system.Pressure output maps are shown for one woman with stress urinary incontinence (SUI) and one with a history of SUI who underwent successful midurethral sling insertion. We also show a summary of 3D pressure-measurement patterns of 44 women who underwent pressure measurements to evaluate qualitatively the 3D pressure profile of the urethra in an effort to better understand pelvic floor and urethral sphincter physiology.Advanced HRM technology to measure urethral pressures under cough and strain conditions without withdrawal techniques provides new insights into the continence mechanism in continent and incontinent women and after continence surgeries.
