A new urodynamic test which detects the entry of fluid into the proximal urethra has been used in the investigation of women with urinary incontinence. The test is positive if a "fluid bridge" is established between the bladder and a test point in the urethra. The test results from 30 incontinent patients were compared with those from 30 women with normal urinary control who had been matched for age and parity. Twenty-four of the incontinent women had a positive fluid bridge test (FBT) at 0.5 cm from the bladder neck compared with 6 of the women in the control group. The difference between the test results in the two groups was highly significant (X2 = 19.27, p less than 0.001). In the incontinent patients a diagnosis was made after full clinical examination (which included an attempt to demonstrate stress leakage), cystometry and urethral closure pressure profile measurement. In a number of cases (23%) the only evidence of urethral incompetence was a positive FBT. We conclude that the FBT is a more sensitive index of sphincter weakness than are other non-radiological urodynamic tests.
一种用于检测液体进入近端尿道的新型尿动力学测试已被用于对尿失禁女性的调查。如果在膀胱和尿道中的一个测试点之间建立了“液桥”，则该测试为阳性。将30名尿失禁患者的测试结果与30名年龄和产次相匹配的排尿控制正常的女性的测试结果进行了比较。24名尿失禁女性在距膀胱颈0.5厘米处的液桥测试（FBT）呈阳性，而对照组中只有6名女性呈阳性。两组测试结果之间的差异非常显著（X2 = 19.27，p < 0.001）。在尿失禁患者中，在进行全面临床检查（包括试图证明压力性漏尿）、膀胱测压和尿道闭合压力曲线测量后做出诊断。在一些病例（23%）中，尿道功能不全的唯一证据是FBT呈阳性。我们得出结论，与其他非放射学尿动力学测试相比，FBT是括约肌无力更敏感的指标。
