Zusammenfassung
Mundschleimhaut ist ein ideales Material, um Urothel der Harnröhre zu ersetzen. Ihre Verwendung bietet sich v. a. dadurch an, dass sie einfach zu gewinnen ist, an ständigen Kontakt mit Feuchtigkeit gewöhnt ist und in jeder Lokalisation der Harnröhre einsetzbar ist. Die Strikturlänge, die Lokalisation und der Zustand des betroffenen Harnröhrenabschnitts entscheiden über die Operationstechnik, in der die Mundschleimhaut Verwendung findet. Offene Harnröhrenplastiken mit Mundschleimhaut haben eine Erfolgsrate von > 85 % und sollten nach erfolgloser Urethrotomie sowie längerstreckigen Strikturen eingesetzt werden.
Abstract
Buccal mucosa is the ideal material for urethral reconstruction because it is easy to harvest, is accustomed to permanent moisture and can be used at any location in the urethra. Stricture length and local conditions of the urethra have to be considered to decide which technique is required to reconstruct the urethra. Open urethroplasty with buccal mucosa has a success rate over 85 % and should be used after unsuccessful internal urethrotomy and primarily in longer strictures.
