Value of Perineal Ultrasonography in Genuine Stress Urinary Incontinence / 대한비뇨기과학회지

ABSTRACT

The study was designed to determine the effectiveness of perineal ultrasonography compared with chain cystourethrography(CUG) in genuine stress urinary incontinence and to evaluate the diagnostic significance of perineal ultrasonography in 30 women with genuine stress urinary incontinence. The distinctive characteristic of perineal ultrasonography is simple, noninvasive, free of radiation exposure, comfortable, and not shameful out-patient procedure. We measured the posterior urethrovesical angle(PLRVA) at rest and during strain, and calculated the difference between the two angles. The mean value of PUVA at resting state were 134.7' in perineal ultrasonography group and 135.5' in chain CUG group(p=0.8235). During strain state, PLRVA was 146.2' in perineal ultrasonography group and 147.4' in chain CUG groupt=0.8341) The difference between PUVAs at rest and during strain was 12.1' in perineal ultrasonography group and 12.0' in chain CUG group(p=0.9022). The percentage of patients' subjective satisfaction with perineal ultrasonography was 96%, however the percentage of discomfort in chain CUG was 96%. In conclusion, perineal ultrasonography is a very comfortable and useful diagnostic method in genuine stress urinary incontinence, to replace chain CUG.
