Patients undergoing urinary diversion are at high risk for developing stone disease due to the metabolic and structural features intrinsic to the creation of a urinary reservoir. The utilization of shockwave lithotripsy as well as antegrade and retrograde endoscopic techniques in appropriately selected patients affords a relatively safe and effective means of stone removal. This review focuses on the etiology of stone formation in patients with urinary diversion and examines the most relevant and current reports on expulsive techniques and their associated outcomes for patients within this population who develop upper urinary tract calculi.
