MANAGEMENT OF UNILATERAL RENAL CYSTINE CALCULI VIA PERCUTANEOUS NEPHROLITHOTRIPSY IN A CHILD WITH A CONTRALATERAL NON-FUNCTIONAL KIDNEY

A Case Report

Abstract

A 2-year old boy visited our clinic with a chief complaint of high fever. A past history of acute renal failure due to cystine stones and cystinuria was expressed. Abdominal rentogenograms and CT demonstrated a right ureteral stone and a left renal stone. Furthermore renogram evaluation indicated non-function of the right kidney and dysfunction in the left kidney. Since right ureteral stone moved into bladder seven days post-admission, right ureteroscopy, left PNL, and cystolithotripsy were performed. Considering that right ureteral stenosis was determined by ureteroscopy, balloon dilation against the stenotic ureteral wall was performed. Left PNL and cystolithotripsy were successfully performed. No intraoperative complications occured and no symptoms of signs of recurrence of the underlying metabolic disease were evident four months postoperatively.
