Peritoneal dialysis is an important method of renal replacement therapy in cases of renal failure, which may be acute, categorized as prerenal, intrinsic or postrenal failure, and is usually reversible once the cause is rapidly identified and promptly corrected before kidney damage occurs. Dialysis is the alternative in cases where no donor for the transplantation can be found, which may be hemodialysis or peritoneal dialysis which may be acute or chronic, and in cases of the latter a permanent peritoneal catheter is fixed under general anesthesia. There are two main types for CPD, Continuous Ambulatory Peritoneal Dialysis and Continuous Cycler-Assisted Peritoneal Dialysis where a machine is used to fill the abdomen, not the patient himself. Both methods can sometimes be used in the same patient.
