Urinary diversion to the colon may produce a metabolic encephalopathy with elevated blood ammonia levels. The condition resembles hepatic encephalopathy but can occur without obvious liver disease. The patient described herein also had a computed tomographic scan showing diffuse brain swelling and superficial contrast enhancement. The condition responds rapidly to lowering of the blood ammonia level and requires a high level of suspicion for diagnosis in the patient who has undergone urinary diversion and has an unexplained metabolic encephalopathy.
尿液转流至结肠可能会导致代谢性脑病，血氨水平升高。这种情况类似于肝性脑病，但可在无明显肝脏疾病的情况下发生。本文所述患者的计算机断层扫描显示弥漫性脑肿胀和表面强化。该病症对血氨水平降低反应迅速，对于接受尿液转流且患有不明原因代谢性脑病的患者，诊断时需要高度怀疑。
