Kidney ultrasound
Non-invasive sound-wave imaging of the kidneys.
Kidney ultrasound is a non-invasive imaging test that uses sound waves to visualize the kidneys in real time.
It evaluates for stones, obstruction (hydronephrosis), cysts, and solid masses, and is often used to monitor known kidney conditions.
The exam is painless, requires no intravenous contrast, and uses no ionizing radiation, making it appropriate even for patients in whom contrast or radiation is a concern.
It is often a first-line imaging study in urologic evaluation, with results guiding any further imaging or intervention.
