Renal (Kidney) Ultrasound
Ultrasound or sonogram of the kidneys is a test that is commonly performed in the urology office. High frequency sound waves are used to produce an image of the kidneys to look for obstructions, stones, or suspicious masses.
The procedure is noninvasive and is not at all painful. A technician applies a transparent gel to the skin over the flank or abdomen and scans the kidneys with a hand held wand. The recorded images are then interpreted by a qualified radiologist. Results are available within several days after the exam.
