The purpose of this report was to describe an uncommon congenital anomaly in a dog. An 8-year-old, mixed-breed, male dog, was referred because of progressive difficulties on defecation. A complete diagnostic work-up (hematological analysis, radiology, ultrasound, and computed tomography), followed by surgery and histopathology, allowed us to diagnose the condition as unilateral urogenital disontogeny. The disorder was characterized by unilateral anomalies of the urinary tract (ectopic and dilated hydroureter, hydronephrosis, and renal dysplasia) associated with ipsilateral anomalies of the genital system (partial permanence of the duct of Wolff evolved into an epididymal-like structure and testicular agenesis). En bloc surgical excision of the complex of urogenital anomalies was performed with no complications during or after surgery. Surgery was considered to be effective in this dog since he no longer showed clinical signs of illness.
本报告的目的是描述一只犬类罕见的先天性异常。一只8岁的混种雄性犬因排便逐渐困难而前来就诊。经过全面的诊断检查（血液学分析、放射学、超声和计算机断层扫描），随后进行手术和组织病理学检查，我们将该病症诊断为单侧泌尿生殖系统发育不全。该病症的特征为泌尿系统的单侧异常（异位和扩张的输尿管积水、肾盂积水和肾发育不全），伴有生殖系统同侧异常（沃尔夫管部分残留并演变成类似附睾的结构以及睾丸发育不全）。对泌尿生殖系统异常复合体进行了整块手术切除，手术期间及术后均无并发症。由于这只犬不再表现出疾病的临床症状，手术被认为是有效的。
