Abstract:

Ultrafiltration failure is a common complication and an important cause of peritoneal dialysis failure. Ultrafiltration failure is defined as that the net ultrafiltration volume is less than 400 ml after a 4-hour dwell with 4.25% dextrose dialysis solution. According to its pathophysiological mechanisms, the ultrafiltration failure has been divided into 4 types: type 1 ultrafiltration failure is caused by increase of effective peritoneal surface area; type 2 ultrafiltration failure is caused by decrease of osmotic conductance to glucose; type 3 ultrafiltration failure is caused by decrease of effective peritoneal surface area; and type 4 ultrafiltration failure is caused by absorbance of a lot of water through the peritoneal lymphatic system or local tissue gap. Beneficial methods to prevent and treat ultrafiltration failure include rational use of high glucose dialysate, effective prevention and treatment of peritoneal dialysis-related peritonitis, protection of residual renal function, appropriate use of biocompatible dialysates, and application of drugs to improve peritoneal damage and fibrosis.

Key words: Ultrafiltration failure, Peritoneal dialysis, Diagnosis, Treatment
