Percutaneous Dilation and Stenting of Neoinfundibulum in Treatment for Calyceal Diverticulum in an Adolescent Male

Abstract

ABSTRACT

Calyceal diverticula are eventrations of the upper collecting system lying within the renal parenchyma and communicating with the main collecting system through small infundibuli. If they are left untreated, stasis of urine can promote infections or stone formation. Traditionally, these diverticuli have been managed with open techniques and more recently with percutaneous or endoscopic techniques. This report describes a modification of the percutaneous technique used successfully in the treatment of a 14-year-old boy in whom a neoinfundibulum was created, dilated, and temporarily stented to provide drainage of the diverticulum.
