[Management of Cast Nephropathy].

Myeloma cast nephropathy is the most common cause of acute kidney injury in patients affected by multiple myeloma. The mainstay of management of cast nephropathy is the clone-based therapy by reducing production and thereby precipitation of light chains. Adjuvant therapy consists of inducing high urine volume flow and alkalinisation, where possible. Extracorporeal removal of light chains is still debated and the advantages of these procedures are not established. The use of safe and low expensive membranes may encourage their use and address their utility.
