RESUMO
@#Management of nephrolithiasis in patients with urinary diversions pose a unique therapeutic challenge for the following reasons: 1) retrograde ureteral access is difficult to perform through a bowel diversion and 2) percutaneous renal access becomes challenging because of inability to do a retrograde pyelogram. For this reason, image-guided access through a combined ultrasound and fluoroscopic guidance are both necessary. This clinical problem becomes even more complicated when dealing with a solitary functioning kidney. Treatment should be precise in order to avoid any complications that may progress to renal failure. Presented here is a 15-year-old male adolescent who had previously undergone a radical cystectomy with an ileal conduit for a rhabdomyosarcoma of the bladder last 2008, and complained of flank pain, fever and foul-smelling urine. Imaging studies showed left obstructive hydronephrosis with ureterolithiasis and nephrolithiasis, and an atrophic contralateral kidney. A preliminary nephrostomy tube drainage was done to recover renal function, followed later by percutaneous endoscopic stone management. Discussed here are the challenges involved in his therapy as well as the advantages of a stepwise approach including the short-term outcomes.
