Unusual cause of irreversible acute kidney injury postgastrectomy

Abstract

A 56-year-old male was diagnosed to have carcinoma stomach following evaluation of lack of appetite and weight loss. He underwent neoadjuvant chemotherapy and gastrectomy. Following surgery he developed progressive renal failure. A renal biopsy led to the diagnosis of oxalate nephropathy. Despite treatment his renal functions never recovered. Oxalate nephropathy is an underappreciated cause of renal failure postgastrectomy. It can cause irreversible renal failure unless detected and treated early.
