Clinical Information
- Abnormal enlargement of a kidney, which may be caused by blockage of the ureter (such as by a kidney stone) or chronic kidney disease that prevents urine from draining into the bladder.
- Abnormal enlargement or swelling of a kidney due to dilation of the kidney calices and the kidney pelvis. It is often associated with obstruction of the ureter or chronic kidney diseases that prevents normal drainage of urine into the urinary bladder.
- Collection of urine in the renal pelvis that results in dilatation of the renal pelvis and calyces. It is caused by obstruction of urine flow, nephrolithiasis, or vesicoureteral reflux. Signs and symptoms include flank pain, nausea, vomiting, fever, and dysuria.
- Distention of the pelvis and calices of the kidney with urine, as a result of obstruction of the ureter, with accompanying atrophy of the parenchyma of the organ.
- Water retention in the kidney
