A 2-month-old male British Shorthair cat was referred with suspected atresia ani. Physical examination revealed an imperforate anus and dribbling of faecal discharge through the penis. Radiographic findings, along with a retrograde urethrogram, confirmed the diagnosis of type II atresia ani with a urethrorectal fistula. Surgical anoplasty was performed and the patient recovered well. At 8 months of age, surgical treatment for the congenital urethrorectal fistula was carried out via a single perineal approach, including fistulectomy and castration through the same incision. Postoperative short-term outcomes were excellent, with normal defecation and urination.
Atresia ani is a rare congenital anomaly, particularly in male cats. Despite advancements in surgical techniques, this case represents the first successful staged surgical management of urethrorectal fistula with type II atresia ani in a male kitten, potentially influencing future surgical approaches for similar congenital anomalies.
一只2个月大的雄性英国短毛猫因疑似肛门闭锁被转诊。体格检查发现肛门闭锁，粪便通过阴茎滴出。影像学检查结果以及逆行尿道造影证实了Ⅱ型肛门闭锁合并尿道直肠瘘的诊断。进行了手术肛门成形术，患者恢复良好。在8个月大时，通过单一会阴入路对先天性尿道直肠瘘进行了手术治疗，包括瘘管切除术和通过同一切口进行去势。术后短期效果极佳，排便和排尿正常。
肛门闭锁是一种罕见的先天性异常，在雄性猫中尤为少见。尽管手术技术有所进步，但该病例代表了首次成功地对雄性小猫的Ⅱ型肛门闭锁合并尿道直肠瘘进行分期手术治疗，可能会影响未来对类似先天性异常的手术方法。
