Abstract

The clinical picture and prognosis are usually indolent, however, it may be associated with urinary tract infections, nephrolithiasis and, less frequently, hematuria and low back pain. We present below the case of a patient with persistent macro hematuria of 9 years of evolution, with multiple inconclusive studies during those years, with a final diagnosis of medullary sponge kidney.
