C.M.C was the first hospital in North India to start Peritoneal Dialysis (P.D). Initially it was done by the Department of Surgery in the mid-sixties. In 1970-71 a 3 bed Renal Unit for Peritoneal Dialysis was started in the Department of Medicine. Since 1971 regular peritoneal dialysis and percutaneous kidney biopsies have been done. In January 1988 an independent Nephrology Unit was created with facilities for Haemodialysis and later on for Renal Transplantation. Currently in addition to these facilities, the Unit has been performing plasmapheresis, slow continuous therapies (continuous veno-veno haemodialysis, continuous veno-venous haemofiltration, continuous arterio-venous haemodialysis and charcoal haemoperfusion.
