Zusammenfassung

Hintergrund

Die Problematik der Rekonstruktion der Harnröhre nach einer misslungenen HYP-Operation (HYP: Hypospadie) reicht in ihrer Komplexität von einer banaler Meatusstenose bis zu der Notwendigkeit, die komplette vordere Urethra neu zu bilden.

Fragestellung

Pathologische Befunde und angewandte operative Methoden zur Rekonstruktion der Harnröhre nach misslungener HYP-Operation werden geschildert.

Material und Methode

Verschiedene pathologische Befunde nach nicht gelungener HYP-Operation werden entsprechend der Lokalisation und Ausprägung beschrieben.

Ergebnisse

Das prinzipielle Vorgehen zum Beheben verschiedener pathologischer Befunde nach fehlgeschlagener HYP-Korrektur wird beschrieben.

Schlussfolgerungen

Die erfolgreiche Rekonstruktion der Urethra bei Patienten mit vorausgegangener HYP-Operation bedarf Erfahrung, guter Kenntnisse der Anatomie der normalen und hypospaden Urethra und des Penis. Das Beherrschen der plastischen chirurgischen Techniken und Kenntnisse über die verschiedenen operativen Methoden der HYP-Chirurgie sind Voraussetzung.

Abstract

Background

The tasks involved in reconstructing the urethra after failed hypospadias repair range from correction of a trivial meatal stenosis to reconstruction of the entire anterior urethra.

Objectives

To describe pathological findings in the urethra after failed hypospadias repair and the respective surgical methods used for their correction.

Materials and methods

The various pathological findings after unsuccessful hypospadias surgery are classified according to their location and complexity.

Results

The general rules of reconstruction that should be applied in each particular situation are described.

Conclusions

Successful reconstruction of the urethra in patients with failed hypospadias surgery requires experience and good knowledge of the anatomy of the normal and hypospadic urethra and penis. Mastery of plastic surgical techniques and profound knowledge of the various surgical methods of hypospadias surgery are essential.
