About

Intraperitoneal Pressure is associated with the complications of increased intra-abdominal pressure in peritoneal dialysis patients. Due to the complicated operations, routine measurement of hydrostatic intraperitoneal pressure is not used routinely in adult peritoneal dialysis patients. There ars some limitions in equations from previous studies, such as the sample size was small , and the study population was limited. In the study, we aim to develop and validate an equation for estimating intraperitoneal pressure in peritoneal patients.
