ACQUIRED CYSTIC KIDNEY-DISEASE

Patients with end-stage kidney disease, particularly those treated wit h dialysis, develop proliferative processes in their native kidneys th at result in the formation of multiple acquired renal cysts, renal ade nomas, and carcinomas. Cyst hemorrhage and perinephric hemorrhage are important complications of acquired cystic disease. Patients may succu mb from metastatic renal cell carcinoma. CT scans, ultrasound, and MR imaging may all be used for evaluating acquired cystic kidney disease and its complications. Guidelines for monitoring the native kidneys of dialysis patients and of renal transplant recipients for the developm ent of carcinoma are provided.
