| Perineal ultrasonography is a noninvasive method that is easier than chain cystoure-thrography in thediagnosis of stress urinary incontinence(SUI). We report the findings of stress urinary incontinence at peritonealultrasound and its differential points form normal control. Twenty-two patients with SUI and l6 normal controlswere included in our study. Aloka SSD 650 with 3.5MHz convex transducer was used, and sagittal image through thebladder, bladder base, urethrovesical junction and pubis was obtained from the vulva area, We measured thepdsterior urethrovesical angle(PUVA) at rest and stress, and calculated the difference between the two angles. Wealso measured the distance of bladder neck descent during stress and the diameter of proximal urethra at rest. Thedata were analyzed with student t-test. At rest, PUVA was 135.3°in patients with SUI group and 134.5°in normalcontrol group(P=0.8376). During strees, PUVA was 149.5°in SUI group and 142.1°in normal group(P=0.0135). Thedifference PUVAs at rest and during stress was 14.2°in SUI group and 7.6°in normal group(P=0.0173). The distanceof bladder neck descent during stress was 14.5mm in SUI group and 9.8mm in normal group(P=0.0029). The diameter ofproxiaml urethra at rest was 4.4mm in SUI group and 3.6mm in normal group(P=0.0385). In conclusion, ultrasoundparameters that include the PUVA during stress, the difference between PUVAs at rest and during stress, thedistance of bladder neck descent during stress and the diameter of proximal ureyhra at rest are useful indiagnosis of the stress urinary incontinence. |
