[Significance of the urethral pressure profile in the diagnosis of urethral diverticulum].

Diverticulum of the urethra was diagnosed by us in ten women during the past two years. In nine of these, the urethral pressure profile showed a characteristic course: In the region of the diverticulum--confirmed subsequently by radiography--a drop in pressure was recorded as a sign of damage to the wall. The value and importance of the individual steps in the diagnosis of diverticula are discussed. Suspicion of a diverticulum in the urethra can be raised by careful anamnesis and by means of the urethral pressure profile. This suspicion can be safely confirmed or refuted via urethrography using the double-balloon catheter.
