Sterile peritonitis in the peritoneal dialysis patient.

摘要

Peritonitis is a serious and common problem in the peritoneal dialysis (PD) population. Abdominal pain, fever, and cloudy PD fluid usually heralds the onset of infective peritonitis. However, in up to 20% of cases, no organism is identified. In these situations, diagnosis can be made only by excluding a microbiological cause and performing a cytological examination of the PD fluid to determine the cellular or noncellular constituents. This review examines the differential diagnosis of sterile peritonitis and uses cytological examination to facilitate the appropriate diagnosis.
