title: Ammoniagenic coma following ureterosigmoidostomy.
abstract: Ammoniagenic coma or episodic stupor is a rare complication of ureterosigmoidostomy. We report a case with the unusual features of normal liver function and normal liver biopsy. With extremely rare exception, ammoniagenic coma will not occur in the presence of normal ornithine-urea cycle synthesis in the liver.
