What is Ultrasonography (also called ultrasound or sonogram)?

Ultrasound uses high-frequency sound waves to create real-time images. It is a simple and painless way for urologists to look at many organs. It is flexible and offers helpful information, without using dyes or radiation.

A small probe and gel are placed on the skin. The transducer can then collect the sound waves from organs to create an image. The images look like thin, flat sections of the body on a computer screen. Newer technology can create three-dimensional (3-D) ultrasound images.

These exams help your doctor diagnose many things, including organ damage. It can see the bladder, ureters and the lower part of the kidney. It is used to evaluate symptoms like:

  • Pain
  • Swelling
  • Infection

Ultrasound is painless, safe and generally risk-free.
