The modified fluid bridge (flow) test (MFBT) is a simple procedure for detecting bladder neck incompetency using a fluid-filled catheter. The Stresscath (Hollister) female diagnostic catheter is an improved version of the MFBT. We evaluated the ability of the Stresscath to detect bladder neck incompetence in the first 66 female patients referred for urodynamics. The absence or presence of stress incontinence was based on the results from history and physical examinations. The results from the Stresscath correlated with the history showed that the Stresscath had a sensitivity of 0.73 and a specificity of 0.88 in determining stress incontinence due to bladder neck incompetency. The results from the Stresscath correlated with the physical examination (Marshall test) showed that the Stresscath had a sensitivity of 0.86 and a specificity of 0.87 in determining stress incontinence due to bladder neck incompetence. The Stresscath was at least as accurate as the urethral pressure profile in the diagnosis of stress incontinence, at less capital cost.
改良液桥（流动）试验（MFBT）是一种使用充满液体的导管检测膀胱颈功能不全的简单方法。应力导管（霍利斯特公司）女性诊断导管是MFBT的改良版本。我们评估了应力导管在最初66例因尿动力学检查而转诊的女性患者中检测膀胱颈功能不全的能力。压力性尿失禁的有无基于病史和体格检查结果。应力导管与病史相关的结果表明，在确定因膀胱颈功能不全导致的压力性尿失禁方面，应力导管的敏感性为0.73，特异性为0.88。应力导管与体格检查（马歇尔试验）相关的结果表明，在确定因膀胱颈功能不全导致的压力性尿失禁方面，应力导管的敏感性为0.86，特异性为0.87。在压力性尿失禁的诊断中，应力导管至少与尿道压力描记法一样准确，而且成本更低。
