Extracorporeal shock wave lithotripsy for a ureteral stone in crossed fused renal ectopia.
BACKGROUND
A 63-year-old woman presented with right flank pain and macroscopic hematuria.
A plain film showed a calcific shadow on the right iliac bone. On excretory urography, the right kidney was seen in the normal position, but the left kidney was not. Bilateral retrograde pyelogram revealed the S-shaped kidney and mild obstruction from a 12 x 5 mm calculus in the proximal ureter of the crossed kidney. The patient was successfully treated with in situ extracorporeal shock wave lithotripsy (ESWL) treatment and is stone free at 1 month follow up.


CONCLUSIONS
We believe this is the first case of successful ESWL in a crossed kidney.
