title: [ESWL for urolithiasis in a patient with transileal ureterocutaneostomy].
abstract: We present a case of urinary stone originated in the upper urinary tract and impacted within the ureteroileal anastomosis, in a patient with ileal conduit urinary diversion. Extracorporeal shock wave lithotripsy (ESWL) showed itself resolutive. Patients with urinary diversion have multiple risk factor for calculi formation (acidosis with concomitant hypercalciuria, upper urinary tract infections with urease producing bacteria, urostasis due to ureterointestinal anastomosis or ureteral narrowing), as well as predisposing conditions for stones to impact along the ureter or within the ureterointestinal anastomosis. Follow-up of these patients has to be very careful in order to avoid obliterative pyeloureteritis, the major complication of stone disease in patients with urinary conduit diversion.
