女性尿失禁患者尿动力学检查

目的:了解尿动力学检查在诊断女性尿失禁中的意义.方法:选取200例女性尿失禁患者为病例组和因上尿路疾病需要手术治疗而下尿路功能正常的20例女性患者为对照组.病例组依据临床和尿动力学检查结果分为急迫性尿失禁患者90例,真性压力性尿失禁患者70例,充溢性尿失禁患者40例.比较各组病例与对照组之间尿动力学参数的差异.结果:真性压力性尿失禁组的最大逼尿肌排尿压、最大尿流率时逼尿肌压力、最大尿道压和最大尿道闭合压显著低于对照组(P＜0.05);急迫性尿失禁组最大膀胱压测定容量显著低于对照组(P＜0.05);充溢性尿失禁组最大尿流率、膀胱顺应性、最大逼尿肌排尿压和最大尿流率时逼尿肌压力显著低于对照组,残余尿量和排尿前最大逼尿肌压力显著高于对照组(P＜0.05).结论:尿动力学检查能为女性尿失禁患者的诊断和治疗提供客观依据.

Urodynamic study in women with urinary incontinence

Aim: To investigate the application of urodynamics in diagnosing women with urinary incontinence.Methods: A total of 200 women with urinary incontience and 20 with upper urinary tract disease and normal lower urinary tract function were included in this study. Urodynamic examinations were performed in all patients according to the recommendations of the International Continence Society (ICS). The women with urinary incontinence were divided into three groups according to the urodynamic examinations, including the genuine urinary stress incontinence group (70 cases), urgent urinary incontinence group (90 cases) and overflow urinary incontinence group (40 cases). Results:Maximum detrusor pressure in voiding, detrusor pressure at maximum flow rate, maximum urethral pressure and maximum urethral closure pressure of genuine stress urinary incontinence group, maximum cystometric capacity of urgent urinary incontinence group, maximum flow rate,bladder compliance,maximum detrusor pressure in voiding, detrusor pressure at maximum flow rate of overflow incontinence group were significantly lower than those of the control group, but the detrusor pressure before voiding and post void residual were significantly higher in overflow urinary incontinence group than those of the control group. Conclusion: Urodynamic testing should serve as an essential part of disagnosis and therapy for women with incontinence.
