Transrectal ultrasonography in lower urinary tract for women without stress urinary incontinence / 대한비뇨기과학회지

ABSTRACT

Radiographic chain cystourethrography(CUG) for stress urinary incontinence(SUI) has several disadvantages including the risk of excessive irradiation, the time required for the test, and the discomfort of the patients. Nowadays it is widely accepted that transrectal ultrasonography for evaluating bladder and urethra provides similar information about SUI comparing with the conventional radio- graphic examination. Also some authors suggested that chain CUG is not essential any more to evaluate SUI, transrectal ultrasonography only is enough to evaluate SUI. So we try to perform tansrectal ultrasonographic examination in evaluating SUI before and after the operation but we need control parameters in normal women as a guideline of diagnostic criterial for SUI. So we analyzed the data of ultrasonographic findings in twenty women without SUI. Our data revealed that PUV angle in resting state is 127.5 degree, in stress state 145.7 degree and AIUA in resting state 40.5 degree, in stress state 54.0 degree. Those are little larger than Green`s criteria in chain CUG. Bladder neck descent was 5.7mm between resting and stress state. Interestingly amount of bladder neck descent was negaively correlated with the number of delivery and the aging. We hope that these sonographic parameters in control group will be helpful to be a guideline of diagnostic criteria in SUI.
