Urinary Tract Videos
Point-of-care ultrasound (POCUS) of the urinary tract is a non-invasive bedside tool used to evaluate acute flank pain, hematuria, acute kidney injury, and urinary retention. It primarily targets renal obstruction (hydronephrosis), kidney stones, and bladder volume
Urinary Retention with Bilateral Severe Hydronephrosis
Urinary retention is typically a very painful acute problem for a patient. It is, however, the development from a more chronic problem. This is more common in male patients and is most often due to an enlarged prostate.
Ureterolithiasis at the Ureterovesical Junction (UVJ) with Twinkle Artifact
In this brief video we see a patient with ureterolithiasis located at the ureterovesical junction which is a common area that passing stones becomes lodged. In addition to identifying the ureterolithiasis we can see twinkle artifact which a a reverberation artifact when color doppler is utilized.
Basic Renal Ultrasound
In this video the basic renal ultrasound is reviewed and binary questions are discussed.
POCUS in Acute Renal Failure
POCUS can be used in the acute setting to determine if obstruction is contributing to an acute episode of renal failure. In this video the causes of unilateral and bilateral obstruction, including the degrees of hydronephrosis, will be reviewed.
