Standard peritoneal dialysis (SPD) requires four daily glucose-based continues exchanges, which increase oxidative stress (OS), inflammation, and loss of residual renal function (RRF), favoring peritoneal fibrosis and technique failure. Incremental peritoneal dialysis (IPD), guided by baseline RRF, uses fewer exchanges and reduces glucose exposure. This study aimed to compare OS and RRF preservation between IPD and SPD in incident peritoneal dialysis patients.
Valdivia et al. (2026) studied this question.
