Thirty women with urinary incontinence underwent detailed preoperative and postoperative clinical and urodynamic evaluation before and after the pessary test. The urodynamic changes observed with the pessary test (P less than .01) were very similar to those seen after corrective incontinence surgery. The pessary test differentiated patients with bladder instability from those complaining of stress urinary incontinence with a correctable anatomic defect. Pre- and postpessary test voiding urethrocystometry and uroflometry demonstrated absence of urethral obstruction to the free flow of urine. The pessary test is a simple, inexpensive, reliable diagnostic and prognostic tool. It simulates the results of anticipated incontinence surgery and restores continence without causing compression of the urethra as does the Bonney test.
30名尿失禁女性在子宫托试验前后接受了详细的术前和术后临床及尿动力学评估。子宫托试验观察到的尿动力学变化（P<0.01）与矫正性尿失禁手术后观察到的变化非常相似。子宫托试验可区分膀胱不稳定患者和主诉有可矫正解剖缺陷的压力性尿失禁患者。子宫托试验前后的排尿尿道膀胱测压和尿流率测定表明，尿液自由流动不存在尿道梗阻。子宫托试验是一种简单、廉价、可靠的诊断和预后工具。它模拟了预期的尿失禁手术结果，并且与邦尼试验不同，不会因压迫尿道而恢复控尿。
