Abstract
Renal replacement lipomatosis (RRL) is a rare benign condition of the kidney in which there is proliferation of fat within renal sinus, hilum and peri-renalspace, thus replacing the renal parenchyma. The pathogenesis of RRL is unknown, although it is generally associated with aging, renal atrophy, long-standing chronic urinary infections. We report two cases of RRL, one of right kidney and other left, both of them associated with kidney stones. The patients were 45 and 65 years old respectively andwere admitted with fever and pain in abdomen. Autopsy performed showed right RRL associated with staghorn calculus and pulmonary tuberculosis in the first patient and left RRL with renal calculus in the pelvis and left pyelonephritis with perinephric abscess and right sided pyelonephritis in the second patient.
