[One-step urethroplasty--indications, results and surgical peculiarities].

In a representative patient group the long-term results were examined after one-stage urethroplasty with a subcutaneous pedicle skin flap. The used modification in which an intact strip of epithelium is buried shows good to satisfactory results in 80% of the cases, but in more than 60% a diverticulum of the neourethra was found. Therefore, in 25% of all urethroplasties a secondary resection of the diverticulum was necessary. First experiences with the use of a skin patch to reconstruct the urethra have shown that formation of diverticula can be prevented by this technique. The pre-, intra- and postoperative measures (epilation, secretion drainage, temporary urinary diversion) which are necessary to achieve good functional results are presented in detail.
