An Introduction to Point-of-Care Ultrasound: Laennec to Lichtenstein

Point-of-care ultrasonography (POCUS) is rapidly evolving as a noninvasive adjunct to physical examination among various specialties. POCUS increases the sensitivity of conventional physical examination by providing the answers to simple clinical questions at the bedside. As such, it can reduce fragmentation of care and expedite management. In addition, using bedside ultrasound as the first-line investigation may eliminate unnecessary radiation and contrast exposure. The advent of highly portable and affordable ultrasound devices has made the use of POCUS more practical and user-friendly, making it the stethoscope of the 21st century. This review will provide an overview of the rationale for integrating POCUS into nephrology practice. We also discuss the current scope of POCUS practice and state of training.
