Anorexia nervosa and nephrolithiasis

Abstract

A patient with primary anorexia nervosa developed acute abdominal pain and hematuria. Cytoscopy and retrograde pyelography confirmed nephrolithiasis. A calcium oxalate stone was passed. The association between anorexia nervosa and nephrolithiasis has not been previously reported. Dietary factors and chronic dehydration are known to contribute to the development of renal stones; therefore, the association may not be coincidental.
