[Retrograde infusion urethrocystography in the diagnosis of urethral strictures in men].

To correct urination the authors used retrograde infusion urethrocystography (RIU) in 102 males. 57 of them had an urethral stricture. A novel urethrocystography device is proposed which facilitates the procedure and is more safe in relation to complication danger. The advantages of the modified RIU over routine one are demonstrated.
