Clinical Information
  • A developmental disorder of the kidney characterized by cystic dilatation of the medullary collecting ducts, resulting in a spongy gross appearance of the kidney. It may be asymptomatic or complicated by hematuria, infections, or renal stones.
  • A non-hereditary kidney disorder characterized by the abnormally dilated (ectasia) medullary and inner papillary portions of the collecting ducts. These collecting ducts usually contain cysts or diverticula filled with jelly-like material or small calculi (kidney stones) leading to infections or obstruction. It should be distinguished from congenital or hereditary polycystic kidney diseases.
