For therapy of strictures of the urethra several procedures are availa
ble. The choice of the adequate strategy requires a rational diagnosti
c, answering questions about localisation, length, shape and funktiona
l effect of the stricture. The most important method is the miction-cy
st-urethrography (MCU). Statements about the dimensions of scarred alt
erations in the corpus spongiosum urethrae are to receive from urethra
l ultrasonic. In addition you can perform the retrograde urethrography
. The functional effects of the urethral stricture should be investiga
ted by uroflowmetry and examinations of the upper urinary tract (ultra
sonic/urography).
