[Comparative study of introital sonography and the urethrocystogram in women before and after surgery for stress incontinence].

In a prospective study of sonographic and radiographic methodologies we compared morphologic bladder data in 30 patients before and after stress incontinence surgery. 18 women were subject to colposuspension according to Burch due to recurrent stress incontinence, 12 women underwent anterior colporrhaphy. Visualisation of bladder, urethra and beta-angle was adequate with both methods. The good visualisation of the anatomical and functional situation of the vesico-urethral area is a major benefit of introital sonography.
