[The urethrocystogram and perineal sonography compared].

Perineal sonography and urethrocystography were performed on 45 patients in the same sitting to evaluate the sonographical method with regard to its applicability as a routine examination method. Corresponding results were obtained 14 times (= 30%). In 31 patients (= 70%) urethrocystographic and ultrasonic measurements diverged. The urethrocystogram must therefore remain an integral part in the work-up of urinary incontinence.
