A 7-year-old castrated male Miniature Poodle had recurrent episodes of cystitis, perineal dermatitis, and urine leaking from the perineum during active micturition. Urethrorectal fistula, urethroperineal fistula, and urethral duplication were diagnosed by positive-contrast fluoroscopic retrograde cystography and voiding cystourethrography. The urethrorectal fistula was resected through an ischial-pubic flap osteotomy, and the urethroperineal fistula was resected by use of a perineal approach. The dog developed urinary incontinence that resolved by 48 hours after surgery. Cystitis and urine scald were not evident 6 months after surgery. Treatment of urethral duplication is not necessary, unless clinical signs of cystitis or urine leakage develop.
一只7岁去势的雄性迷你贵宾犬，在排尿时反复出现膀胱炎、会阴皮炎以及尿液从会阴处漏出的情况。通过阳性对比剂荧光透视逆行膀胱造影和排尿性膀胱尿道造影诊断出尿道直肠瘘、尿道会阴瘘和尿道重复畸形。通过坐骨耻骨皮瓣截骨术切除尿道直肠瘘，采用会阴入路切除尿道会阴瘘。这只狗术后出现尿失禁，但在术后48小时内恢复。术后6个月膀胱炎和尿灼伤不明显。除非出现膀胱炎或尿液漏出的临床症状，否则无需治疗尿道重复畸形。
