Point-of-Care Ultrasound in Nephrology: Beyond Kidney Ultrasound

Area of Science:

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

Background:

• Point-of-care ultrasound (POCUS) is increasingly adopted in clinical practice, especially in nephrology.
• Its application extends beyond renal assessment to comprehensive multi-organ evaluations.
• Challenges like limited training and equipment access persist, particularly in low- and middle-income countries.

Purpose of the Study:

• To review the expanding role of multi-organ POCUS in nephrology.
• To explore applications including congestion, cardiorenal syndrome, and hemodynamic acute kidney injury (AKI).
• To highlight POCUS's utility in evaluating arteriovenous fistulas and electrolyte disorders.

Main Methods:

• This narrative review synthesizes current literature on multi-organ POCUS in nephrology.
• It examines applications in fluid status, cardiac function, and hemodynamic assessment.
• Integration of lung ultrasound, venous Doppler, and focused cardiac ultrasound is discussed.

Main Results:

• POCUS enhances clinical decision-making through rapid, bedside evaluations.
• Studies confirm its utility in managing heart failure, cirrhosis, and volume overload in end-stage renal disease.
• POCUS aids in assessing hemodynamic alterations contributing to AKI.

Conclusions:

• Multi-organ POCUS significantly improves the diagnosis and management of various nephrological conditions.
• Integrating diverse ultrasound techniques guides fluid management and enhances patient outcomes.
• Advancements in technology and training promote POCUS as a global standard in nephrology.
