To evaluate a vaginal device designed to support the bladder neck in women with urinary stress incontinence.
Thirty physically active women completed the study. All underwent urodynamic evaluation at baseline and with the best fitting Bladder Neck Support Prosthesis (Johnson and Johnson Medical Inc., Arlington, Texas) in place. A bladder diary was maintained before enrollment and during 4 weeks of device use. Outcome measures included changes in the 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 (84%) were dry with the device in place. Weekly incontinence episodes decreased from ten to three (p < 0.05). Significant changes in functional urethral length, pressure transmission ratio, and Q-tip 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 symptoms significantly and normalizes urodynamic parameters like a colposuspension.
评估一种用于支持压力性尿失禁女性膀胱颈的阴道装置。
30名身体活跃的女性完成了该研究。所有人在基线时以及佩戴最合适的膀胱颈支撑假体(强生医疗公司,得克萨斯州阿灵顿)时均接受了尿动力学评估。在入组前以及使用该装置的4周内记录膀胱日记。观察指标包括报告的尿失禁发作次数的变化、压力测试时的尿液漏出情况以及佩戴该装置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(84%)在佩戴该装置时无尿失禁。每周尿失禁发作次数从10次减少至3次(p < 0.05)。功能性尿道长度、压力传递率和棉签角度有显著变化。未发现尿道梗阻的证据。受试者认为该装置舒适、易于使用且方便。
膀胱颈支撑假体可显著减轻压力性尿失禁症状,并使尿动力学参数正常化,效果类似于阴道前壁悬吊术。
