Zusammenfassung

Bei einem 1,5 Jahre alten Jagdhundrüden wurde ein traumatisch bedingter Urethradefekt distal der Beckenflexur mit resultierender Harnröhrenfistel mittels Mukosagraft und transurethralem Katheter versorgt. Sechs Monate postoperativ entwickelte sich eine Urethrastriktur. Nach einer Ballondilatation zeigte der Rüde physiologischen Harnabsatz. Die einen Monat nach der Dilatation erneut auftretende Striktur der Urethra wurde mit einer Kombination aus Ballondilatation und Stentimplantation therapiert. Zehn Monate nach der Stentimplantation zeigte der Hund nach wie vor einen unauffälligen Harnabsatz. Zu diesem Zeitpunkt fiel radiologisch eine Deformation des proximalen Stentanteils auf. Weitere Komplikationen ergaben sich während des einjährigen Beobachtungszeitraums nicht. Zukünftig könnten urethrale Stents eine operative Strikturversorgung mittels Resektion des betroffenen Harnröhrenabschnitts und Reanastomosierung der Urethra ersetzen.

Summary

In a 1.5-year-old male hunting dog, a urethral defect distal to the pelvic flexure and the resulting urethral fistula were treated with a mucosal graft and a transurethral catheter. Six months postoperatively a stricture of the urethra occurred. Following balloon dilatation, urination was normal. One month after dilatation, urethral narrowing relapsed and was treated using a combination of balloon dilatation and urethral stent implantation. Ten months following stent implantation the dog continued to show normal urination, although a deformation of the proximal part of the stent was diagnosed radiographically. During the 1-year follow-up no additional complications were observed. In the future, urethral stents may replace surgical resection of the narrowed urethral region and re-anastomosis of the urethra.
