This prospective, randomized, comparative longitudinal study evaluates PD catheter survival and functionality in adult patients with advanced chronic kidney disease undergoing planned PD catheter placement at Hospital Civil de Guadalajara "Fray Antonio Alcalde" from January 2024 to December 2025. Eligible patients are randomized 1:1 to receive either the conventional modified percutaneous catheter placement (Group A) or the Moncrief-Popovich technique with subcutaneous burial of the distal catheter segment until exteriorization (Group B). Data are collected from medical records and nephrology clinic follow-up visits. Outcomes include catheter survival time, functional status at baseline and during follow-up, early and late infectious (exit-site infection, tunnel infection, peritonitis) and mechanical complications, and requirement for dialysis modality change due to catheter failure. Statistical analyses compare rates and time-to-event outcomes between groups; significance set at p \< 0.05. Study procedures comply with institutional ethics oversight and informed consent requirements.
