Imaging Uronephropathies in Children

  • Jeanne S. Chow

The principle that guides imaging of the pediatric genito — urinary tract is the same that guides imaging elsewhere in the body of the child: judicious use of imaging while minimizing ionizing radiation exposure [1] and unnecessary sedation. Ultrasound (US) is the main imaging modality of the genitourinary tract, providing excellent images of the kidneys and bladder. Also, at the level of these organs, an abnormally dilated ureter is easily imaged. Doppler provides additional information regarding vascular flow and is especially helpful in evaluating the main renal artery and veins as well as the arcuate vessels. US contrast agents are used to further evaluate the vascular flow of the kidneys, intrarenal masses, and vesico — ureteral reflux [2]. The main limitation of US is that it provides little functional imaging, instead mainly revealing the physical appearance of the urinary tract.
