| ABSTRACT |
PURPOSE
To compare the estimated degree of urine leakage during straining on standing cystourethrography(CUG) under fluoroscopy with subjective degree and Valsalva leak point pressure(VLPP), and to determine it's clinical significance.
MATERIALS AND METHODS
157 consecutive women who presented with stress urinary incontinence with a mean age of 47 years were included in this study. Standing CUG was performed in the state of urethral catheter insertion and removal. Degree of urine leakage was determined on the fluoroscopy during standing CUG by one urologist, and VLPP was determined by another observer. Each of subjective degree, leakage amount and VLPP was classified into 3 grade and compared it's results to each other.
RESULTS
High correlation was present between the leakage amount and VLPP(p<0.05), and the subjective degree and VLPP(p<0.001), but subjective degree was not highly correlated with leakage amount. Among the clinical parameters, urge syndrome and urge incontinence only had the positive effect to urine leakage.
CONCLUSIONS
Estimation of leakage amount during standing CUG on fluoroscopy seems to be a simple and useful method in the objective evaluation of urine leakage, but it should be considered to be the possibility of over-estimation in the cases of associated urge syndrome and urge incontinence. |
