[The congenital urethral diverticulum of the Male Urethra of adults].

On 4 male adults we demonstrated a congenital urethral diverticulum. The clinical symptomatology mainly showed the inflammatory micturition difficulties, while the obstructive micturtition symptomatology of the childhood was hardly registered by the patients. Injection and micturition urethrogram led to the diagnosis. The mostly additional obstructive effect of a diverticulum can be well diagnosed by urodynamic investigations (cystourethromanometry and uroflowmetry). We used the following treatment: removal of the membrane between diverticulum and urethra and resection of the urethral diverticulum with primary urethral obstruction. The advantages of an open approach in comparison to endoscopical therapy were pointed out.
