Management of Upper Tract Calculi in Patients with Tubularized Urinary Diversions

In a retrospective review of patients with urinary diversion who presented to our stone center during a 3.5-year period 9 underwent 20 procedures for suspected stone episodes. Eventual outcome was excellent in all but 1 patient. In particular, all attempts at retrograde trans-stomal manipulation were successful. We present our cases, and note the technical considerations and management principles. Frequently, these patients are best served by a combination of percutaneous antegrade, trans-stomal retrograde and/or extracorporeal shock wave lithotripsy.
