Autosomal dominant polycystic kidney disease

Autosomal dominant polycystic kidney disease (ADPKD) is relatively a common genetic disorder, occurring in approximately 1 in every 400 – 1000 live births. It is generally an adult-onset, multisystem disorder […]

Bladder ultrasound: calculation of volume

It is crucial to take a look at the urinary bladder when performing kidney POCUS, especially in patients with a dilated collecting system or recurrent urinary tract infections, especially in […]

Parapelvic cyst mimicking hydronephrosis

Parapelvic cysts can mimic hydronephrosis because of their anechoic nature (like urine, clear fluid in the cysts is also black on ultrasound) and close proximity to the collecting system. Hydronephrosis […]

Pleural effusion: The ‘Spine sign’

Spine sign: visualization of the vertebral bodies in the thoracic cavity above the diaphragm – indicative of pleural effusion. In the absence of pleural effusion, the spine is obscured by […]

Lung ultrasound: A and B-lines

Lung ultrasonography can be used alone or in conjunction with limited echocardiography and sonographic assessment of the inferior vena cava to determine a patient’s volume status in day-to-day nephrology practice. […]

Hydronephrosis

On the sonogram, hydronephrosis appears as branching, interconnected areas of decreased echogenicity (anechoic or black in general, indicating the presence of fluid) in the renal collecting system. The source of […]

Obstructed Foley catheter

A normal urinary bladder filled with urine typically appears as a thin-walled, anechoic structure. In contrast, when a bladder is decompressed by a Foley catheter, it is almost empty, and […]
