Renal

A renal vascular evaluation examines blood flow within the kidneys and renal arteries (arteries that supply blood to the kidneys). Renal artery stenosis (a narrowing or blockage of the renal artery) can contribute to hypertension (high blood pressure) and may be a major factor in the development of renal failure. To complete the exam, a technologist will pass a risk-free, painless non-invasive ultrasound transducer (probe or wand) over your abdomen and flank to image the kidney to evaluate the quantity and quality of the blood flow.

Indications

  • Suspected Nutcracker Syndrome (blood in urine or pelvic/abdominal pain)
  • Evaluation for kidney transplant
  • Hypertension
  • Increased creatine
  • Renal artery stenosis follow-up

Patient Preparation

Patients should fast for 6-8 hours prior to their exam. However, patients should take current medications as usual with a small sip of water.
