[Diagnosis of urethral stricture--what is necessary?].

For therapy of strictures of the urethra several procedures are available. The choice of the adequate strategy requires a rational diagnostic, answering questions about localisation, length, shape and functional effect of the stricture. The most important method is the miction-cyst-urethrography (MCU). Statements about the dimensions of scarred alterations in the corpus spongiosum urethrae are to receive from urethral ultrasonic. In addition you can perform the retrograde urethrography. The functional effects of the urethral stricture should be investigated by uroflowmetry and examinations of the upper urinary tract (ultrasonic/urography).
