Summary

Background: Polycystic kidney disease (PKD) is the most common hereditary kidney disease. Peritoneal dialysis (PD) in such patients is restricted because the significantly enlarged kidneys and liver may lead to the increase of intraperitoneal pressure (IPP). Increased IPP points to higher risk of abdominal wall complications and limited infusion volume that cause insufficient dialysis adequacy. Therefore, monitoring IPP is especially important in patients with polycystic kidney disease. However, the standard measurement of IPP is limited due to its cumbersome procedures, the application value of equation for estimating IPP among general peritoneal dialysis patients is not clear in the PKD population and the variables influence the IPP is yet to be explored..

Objective: The main purpose of our study was to validate the existing IPP equations in the PKD patients. Further, more relevant variables were included to optimize the IPP equation. Monitoring IPP can guide the formulation of peritoneal dialysis prescription for ADPKD patients, reduce the occurrence of abdominal wall complications, and the clinical utility and efficiency of PD was expanded.

Methods: A multi-center cross-sectional study. The IPPs were measured using the Durand method, with whole-body and abdominal anthropometry indices, the volume of abdominal cavity, the total kidney volume and liver volume were collected. New equation for estimate IPP in PKD patients were generated by stepwise linear regression modeling. The eIPP were calculated using two developed equations previously. Then The bias, accuracy and precision of eIPP derived from new equation were compared with actual IPP by Durand method respectively.
