To the Editor,

In the recent past, there has been renewed interest in incorporating point-of-care ultrasonography (POCUS) into day-to-day clinical practice. In fact, some authors describe the use of POCUS as a fifth pillar of bedside physical examination in addition to the four traditional pillars, namely, inspection, palpation, percussion and auscultation [1]. POCUS performed at the bedside is primarily intended to provide answers to focused questions such as: “Does the patient have urinary retention?”, “Is there a pericardial effusion?”, “Is the patient hypervolemic?” and narrow the differential diagnosis. In specialties such as emergency medicine, POCUS has become an integral part of post graduate training and more recently, medical schools have been incorporating POCUS training into their undergraduate curricula [2]. In this context, internal medicine and subspecialties including nephrology have been relatively slow to embrace this much needed skill. However, the nephrology...
