POCUS for Nephrologists: Basic Principles and a General Approach

Area of Science:

• Nephrology
• Medical Imaging
• Point-of-Care Diagnostics

Background:

• Point-of-care ultrasonography (POCUS) is increasingly adopted across medical specialties.
• POCUS training and scope of practice are not well-defined within nephrology.
• The diagnostic utility of POCUS beyond renal and vascular access is underappreciated.

Purpose of the Study:

• To review the rationale for nephrologists utilizing POCUS.
• To illustrate POCUS principles with clinical examples.
• To propose a framework for institutional POCUS training programs.

Main Methods:

• Literature review on POCUS in nephrology.
• Discussion of clinical scenarios demonstrating POCUS application.
• Experience-based recommendations for training program development.

Main Results:

• Multiorgan POCUS can improve fluid status assessment sensitivity compared to physical examination alone.
• POCUS can reduce care fragmentation, enable timely diagnosis, and expedite management.
• POCUS utility is operator-dependent, emphasizing the need for quality training.

Conclusions:

• POCUS is a valuable adjunct for nephrologists, particularly for fluid status assessment.
• Standardized training is essential to optimize POCUS performance and integration.
• Further development of POCUS training programs is recommended for nephrology.
