Anuria due to bilateral ureterolithiasis after appendectomy in a child

We report on a boy who presented with acute renal failure and bilateral ureteral obstruction 5 days after an uneventful appendectomy. In contrast to the few cases described in the literature, bilateral ureterothiasis was the pathogenesis of ureteric obstruction. The clinical signs and diagnostic findings, and an overview of the literature are presented. The severity of permanent renal damage in a child underlines the importance of this report.
