Renal Ultrasound: What to Expect
This test uses sound waves to study the renal system. The renal system includes the kidneys, bladder, and ureters. Ureters are the tubes that connect the kidneys to the bladder.
The test is done to look for:
- Changes in the kidneys, bladder, and ureters
- Changes in kidney size or structure
- Kidney stone, cyst, mass, or other obstruction in the kidney
- Stones in the urinary tract
- Changes in the ureters
The test is also done to look at:
- Kidneys before doing a renal biopsy, which removes tissue from the kidney for examination
- Blood flow to the kidneys using a Doppler ultrasound
