Renal (Kidneys)

The kidneys are a pair of bean-shaped organs located behind the upper abdominal cavity on each side of the body. The kidneys remove waste from the blood and produce urine.

What happens during the exam?
The patient lies on a table with the abdominal area exposed. The sonographer (technologist who performs the exam) will put a warm water-based gel on the skin surface. The gel helps to transmit the sound waves by excluding air. An instrument called a transducer, which is about the size of a microphone, will be moved over the skin surface by the sonographer.

How do I prepare for this test?
Please do not eat solid foods or drink anything but water or apple juice for six to eight hours before the exam. Routine medications may be taken. If you are diabetic consult with your doctor.

Note: If the urinary bladder ultrasound is requested by your physician, you should drink 32 ounces of water (two 16 oz bottles) before the exam. Star drinking one hour before the exam. Do not urinate before exam as your bladder must be full.

How long will it take?
About twenty minutes.

Will it hurt?

How will I learn the results?
