Our purpose was to evaluate a vaginal device designed to support the bladder neck in women with urinary stress incontinence.
Thirty-two physically active incontinent women underwent urodynamic evaluation and maintained a bladder diary before enrollment and after 4 weeks of device use. Outcome measures included changes in number of reported incontinence episodes, urine loss on stress testing, and changes in urodynamic parameters with the device in place. Patient comfort, convenience, and satisfaction were also evaluated.
Thirty women completed the study. Twenty-five (83%) were dry with the device in place. Weekly incontinence episodes decreased from 10 to three (p < 0.05). Significant changes in functional urethral length, pressure transmission ratio, and urethral cotton swab stress angle were noted. No evidence of urethral obstruction was noted. The subjects found the device comfortable, easy to use, and convenient.
The bladder neck support prosthesis reduces stress incontinence and normalizes urodynamic parameters in the same manner as a colposuspension.
我们的目的是评估一种旨在支撑压力性尿失禁女性膀胱颈的阴道装置。
32名身体活跃的尿失禁女性在入组前和使用该装置4周后接受了尿动力学评估并记录膀胱日记。结果指标包括报告的尿失禁发作次数的变化、压力测试时的尿液流失以及装置在位时尿动力学参数的变化。还评估了患者的舒适度、便利性和满意度。
30名女性完成了研究。25名（83%）在装置在位时无尿失禁。每周尿失禁发作次数从10次降至3次（p < 0.05）。功能性尿道长度、压力传递率和尿道棉拭子压力角有显著变化。未发现尿道梗阻的证据。受试者发现该装置舒适、易于使用且方便。
膀胱颈支撑假体与阴道悬吊带术一样，可减轻压力性尿失禁并使尿动力学参数正常化。
