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.
在一只1.5岁的雄性猎犬身上，对盆腔弯曲远端的尿道缺损及由此产生的尿道瘘进行了黏膜移植和经尿道导管治疗。术后6个月出现尿道狭窄。球囊扩张后，排尿正常。扩张1个月后，尿道狭窄复发，采用球囊扩张和尿道支架植入联合治疗。支架植入10个月后，尽管经X线检查诊断支架近端有变形，但该犬排尿仍正常。在1年的随访期间未观察到其他并发症。未来，尿道支架可能会取代狭窄尿道区域的手术切除和尿道再吻合术。
