Abhilash Koratala, MD – Point of care ultrasonography (POCUS) is a non-invasive bedside diagnostic tool that aids in clinical decision-making process. In addition, it allows to monitor the efficacy of therapeutic interventions in real time. As such, nephrologists can enhance patient care by adopting this skill, especially in those with simultaneous cardiac dysfunction and difficult to manage fluid status.

Evaluation of Venous Congestion Using Beside Ultrasonography by the Nephrology Consultant: The VExUS Nexus
Abhilash Koratala, MD – In patients with heart failure and cardiorenal syndrome, lingering congestion is associated with worse outcomes. As such, titrating diuretic or ultrafiltration therapy based on objective assessment of volume status plays a crucial role in the management of these patients. Conventional physical examination findings and parameters such as daily weight measurement are not always reliable in this setting. Recently, point of care ultrasonography (POCUS) has emerged as an attractive enhancement to bedside clinical examination in assessing fluid volume status.
Massive Lymphocele Associated with Allograft Hydronephrosis: An Ultrasound Case Study
Harini Bejjanki, MD; Kawther F. Alquadan, MD; Abhilash Koratala, MD – nsplantation. While small collections resolve spontaneously, larger, symptomatic ones may cause obstructive nephropathy requiring percutaneous or laparoscopic drainage.
POCUS Allows for Rapid Elucidation of Acute Kidney Injury in a Patient with Progressive Multiple Myeloma
Liann Abu Salman, MD; Nathaniel Reisinger, MD – A 63-year-old man with past history of multiple myeloma recently started on a regimen of daratumumab, carfilzomib, and dexamethasone was referred to our emergency department for a rapidly rising serum creatinine as high as 10 mg/dL. He complained of fatigue, nausea, and poor appetite. Exam revealed hypertension, but no edema or rales.
Ultrasound Imaging of Quadriceps Tendon in a Recreational Golfer
Shawn D. Felton, EdD, LAT, ATC; Arie J. van Duijn, PT, MScPT, EdD – The patient was a 69-year-old recreational golfer who injured his right . While walking between the 9th and 18th holes, he slipped on pine straw. Ultrasound images of the quadriceps tendon post-injury revealed a full-thickness tear of the Quadriceps tendon, Rectus Femoris and Vastus intermedius.
Pseudoaneurysm of the Dorsalis Pedis Artery Diagnosed on Point-of-Care Ultrasound
Nathan A. Friedman, MD; Caleb P. Canders, MD; Alan T. Chiem, MD, MPH – A 46-year-old man presented with a painless mass on his dorsal right foot one week after striking it on a door. A traumatic hematoma was suspected, and needle aspiration of the mass is considered. However, point-of-care ultrasound performed by the emergency physician identified a pseudoaneurysm of the dorsalis pedis artery, a rare condition that can occur after minor trauma or iatrogenic intervention.
Hematocrit Sign Elucidates Cause of Abdominal Pain
Jeffrey Lam, MD; Steven Montague, MSc, MD – A 78-year-old male with chronic kidney disease on peritoneal dialysis developed unprovoked bilateral pulmonary embolisms. He was started on IV unfractionated heparin, but shortly thereafter developed severe pain and a small firm abdominal nodule near his dialysis catheter site.
Seven Year Old Male with Tricuspid Endocarditis
Omar Damji, BHSc, MSc, MD; Russ A. Lam, BSc, MD; Mark Bromley BSc, MD; Melanie Willimann BSc, MD – Pediatric endocarditis, a rare entity in developed countries, remains a challenging diagnosis to make in children. We present an uncommon etiology of shortness of breath on exertion (SOBOE) in a 7-year-old male presenting with two weeks of nocturnal fever, malaise and fatigue following a viral prodrome.
Diagnosing Early Cardiac Tamponade in Patient with JAK2+ Myeloproliferative Syndrome with Point of Care Ultrasound
Evan Cameron, MD; Lawrence Istrail, MD – Herein is a case of POCUS diagnosing life threatening cardiac tamponade in a patient with a new diagnosis of JAK2+ myeloproliferative syndrome prompting urgent intervention with pericardiocentesis. This case illustrates the utility of POCUS through its ability to serve as a quick diagnostic tool that can hasten intervention for potentially life-threatening conditions.
Hiding in Plain Sight: A Case of Perinephric Abscess Diagnosed by POCUS
David Haughey, MD; Tai Truong, MD – An 87 year old male with obstructive uropathy was initially diagnosed with acute kidney injury (AKI), a new renal mass and hydronephrosis. When transferred to a facility with a hospital medicine POCUS program, the renal mass was correctly identified as a perinephric abscess, which was percutaneously drained leading to resolution of AKI and the underlying infection. Renal POCUS is readily taught via brief educational interventions and empowers providers to identify common (hydronephrosis) and uncommon (perinephric abscess) renal pathology at the bedside.
