Future technologies and techniques in peritoneal dialysis-opportunities and challenges ahead

Area of Science:

• Nephrology
• Biomedical Engineering
• Clinical Trials

Background:

• Emerging technologies in peritoneal dialysis (PD) offer potential patient benefits.
• These innovations include biocompatible solutions, glucose sparing, low-sodium formulations, bimodal solutions, and continuous flow PD (CFPD).
• Current clinical evidence and multicenter study confirmation are often lacking for these advancements.

Purpose of the Study:

• To review the potential benefits of novel PD technologies.
• To analyze the challenges hindering their establishment in clinical practice.
• To assess the feasibility of demonstrating clinical endpoints for these technologies.

Main Methods:

• Literature review of recent technological advancements in peritoneal dialysis.
• Analysis of potential benefits and challenges associated with each technology.
• Evaluation of endpoint demonstration feasibility for clinical validation.

Main Results:

• Several new PD technologies show promise, including biocompatible solutions and CFPD.
• Significant challenges exist in achieving widespread clinical acceptance and validation.
• Demonstrating preservation of residual renal function (RRF) is feasible, but preserving ultrafiltration (UF) capacity is more challenging.

Conclusions:

• Novel PD technologies hold potential for improving patient outcomes.
• Robust clinical demonstration through multicenter studies is crucial for establishing these technologies.
• Endpoint selection significantly impacts the feasibility of demonstrating efficacy, with RRF preservation being more attainable than UF capacity preservation.
