Abstract

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.
