Zusammenfassung

Harnröhrenläsionen können im Rahmen eines Traumas wie z. B. nach Verkehrsunfällen oder iatrogen nach endourologischen oder offenen chirurgischen Eingriffen (z. B. Prostatektomie, Inkontinenz-Operationen) auftreten. Selbst nach unglücklich erfolgten Katheterisierungsmanövern werden urethrale Läsionen angegeben. Das Verletzungsmuster betrifft entweder die anteriore oder die posteriore Harnröhre, selten ist die gesamte Urethra involviert. Detaillierte Anatomiekenntnisse sowie umfassende Erfahrung sind wesentliche Voraussetzungen für einen erfolgversprechenden rekonstruktiven Eingriff. Die Wahl der operativen Technik und des Op-Zeitpunkts hängen von der Traumagenese der Harnröhrenläsion ab. Aufgrund der möglichen Komplikationen wird eine primäre rekonstruktive Versorgung — insbesondere des hinteren Harnröhrenabschnittes — nur in ausgewählten Fällen empfohlen. Ein hier präsentierter therapeutischer Algorithmus soll chirurgisch-interventionelle Komplikationen wie Inkontinenz, Impotenz, rezidivierende Harnwegsinfektionen usw. vermeiden. Letztere beeinträchtigen die Lebensqualität der Patienten beträchtlich, insofern sie nicht selten multiple sekundäre Operationen nach sich ziehen. Somit ist eine sorgfältige primäre Diagnostik unter Zuhilfenahme verschiedener bildgebender Verfahren erforderlich.

Abstract

Urethral lesions may be caused by blunt or penetrating objects in the course of accidents, or can be iatrogenic resulting from invasive measures such as catheterization or other major surgical measures (prostatectomy or sling operations for continence). They can also be caused by foreign bodies deliberately introduced into the urethra. Injuries may primarily affect the anterior or posterior urethra. Urethral reconstruction presupposes knowledge of the precise anatomy of the pelvic region. The surgical techniques used and the timing of reconstructive procedures will depend on the cause and nature of the urethral injury. A definitive surgical intervention in most cases of lesions resulting from accidents is not generally recommended, especially when the lesion is in the posterior urethra. A treatment algorithm should prevent post-surgical complications such as incontinence, impotence, recurring urinary tract infections, etc., necessitating multiple operations, and assure an adequate quality of life. Diagnostic clarification of the exact nature of urethral injuries requires high quality imaging studies by specialists in the field.
