Thank you Jack for helping demonstrate #POCUS for nephrologists! #SWNC2026 As we discussed I'm posting your story to help you finds a donor! Please see the link on the image attached @NephroP

Consummate angler @NephroP (and world-leading #POCUS in nephrology expert) presenting another beautiful slide on the basics of Doppler US Marking the 10th year since the inception of the annual #POCUS in Nephrology Immersion Course at the #SWNC nephrology conference @nkf of AZ!

Happy to contribute a guest post to the @AJKDonline Blog this #NephMadness season, discussing the #POCUS region and the shift from guessing about volume status/hemodynamics to visualizing physiology at the bedside. Thanks @jrkott27 and team. 🔗 ajkdblog.org/2026/03/10/nep…

In adults with type 1 diabetes and chronic kidney disease with albuminuria, the decrease in the urinary albumin-to-creatinine ratio was significantly greater with finerenone than with placebo.

Delighted to contribute the renal and bladder ultrasound chapter for this excellent advanced #POCUS textbook with @ArgaizR and Dr. Beaubien Souligny. Grateful to the editors for the opportunity.

From knobology to #VExUS, from basics to advanced hemodynamics - it’s all happening at the @nkf Arizona #POCUS Immersion Course, March 12-13 2026! Perfect for nephrologists ready to level up their bedside skills 🎯Led by @nephrothaniel, featuring eminent experts in the field. #Nephrology #SWNC2026 Register here 🔗swnephrologyconference.org/poc-ultrasound…

Great proof of concept poster @DallasRenal OP #POCUS in kidney transplant clinic identified hydronephrosis, perinephric collections, vascular flow abnormalities, volume status issues, and bladder outlet problems, obviating hospitalization or ED referral in 90% #kidneywk

Baxdrostat in CKD + HTN: ~8 mmHg lower SBP and ~55% lower albuminuria vs placebo & consistent across subgroups. Aldosterone synthase inhibition looks promising. #Kidneywk #hypertension

Different types of kidney stones: Calcium Oxalate – the most common, harder, and spiky. Calcium Phosphate – smooth and white. Struvite – often large, branch-like stones. Uric Acid – smooth and orange-brown. #Ultrasound #sonologist #KidneyStones #MedicalImaging #Sonography

Finally getting to sit and listen to Dr. Beaubien’s #VExUS talk. I’m usually tied up with other workshop tasks when he or Eduardo Argaiz are presenting - feels good to share the stage today and actually enjoy the learning in peace. #KidneyWk

What a fantastic session at the #POCUS in Nephrology Early Program @ASNKidney #KidneyWeek! Amazing energy and insights — big shout-out to @nephrothaniel and @NephroP for leading such a great program 👏👏

This is hepatization of the right lung seen with #pocus. Note the liver on the right with the bright line of the diaphragm in the center. Above the diaphragm is a hepatized lung that appears very similar to the liver. Without locating the diaphragm, one may assume this is simply an elevated hemidiaphragm and completely miss a pneumonia.

.@ArgaizR on why we use IVC to guess right-atrial pressure instead of internal jugular vein: cardiologists don’t want to switch transducers #kidneywk

Prof. @ArgaizR delivering an outstanding session on integrative volume assessment at the #KidneyWk #POCUS precourse.

Professor @vandyniyyar sharing must-know kidney/bladder #POCUS pearls for nephrologists at the #KidneyWk precourse.

Front-row seats for a masterclass with @NephroP 👏
