Medullary sponge Kidney is a clinical disease entity, which became apparent only when IVPs are done and may be uncovered when hematuria, urinary infection, nephrocalcinosis or frank stones come under investigation. The treatment is limited to the complications, chiefly infection and calculi. We have experienced 8 cases of medullary sponge kidney from 1964 to 1976, and following data were obtained. 1) Clinically, we observed hypertension in 3, flank pain in 4, gross hematuria in 4, renal calculi or calcification in 6 cases, and positive family history or congenital hemihypertrophy were observed in none. 2) In laboratory findings, anemia was present in 1, azotemia in none, hematuria in 5, proteinuria in 3 and urinary tract infection in 4 cases.
