Extracorporeal shock-wave lithotripsy in transplanted kidney.

Urolithiasis is the least described urologic sequela of renal transplantation. We describe a renal transplant patient who presented with painless gross hematuria. An intravenous pyelogram demonstrated a 4 x 7-mm calculi in the region of the ureteropelvic junction, causing moderate hydronephrosis. The patient was treated successfully with extracorporeal shock-wave lithotripsy (ESWL). Serum creatinine and twenty-four-hour creatinine clearance were unchanged from levels prior to ESWL.
