title: [A case of medullary sponge disease associated with horseshoe kidney].
abstract: A 60-year-old man visited our hospital with complaints of micturition pain and interruption of urinary stream. X-ray examinations were performed, showing no bladder and urethral stone. However, KUB revealed bilateral multiple renal stones. Excretory urography showed a horseshoe kidney and a concentration of the contrast medium in the ectatic tubules at the pyramidal apices. Calculi were also located in these ectatic tubules. Thus, we considered that this was a very rare case of medullary sponge disease associated with horseshoe kidney. So far there has been no case report of medullary sponge disease with horseshoe kidney in our country.
