Renal (Kidney) Ultrasound
What Is a Renal Ultrasound?
Patients with lower back and flank pain often need a kidney ultrasound to rule out kidney stones and other kidney diseases. During a kidney ultrasound, we are looking for changes in the shape, size or location of the kidneys, as well as abnormalities in blood flow or unusual masses. More specifically, an ultrasound of the kidneys can detect:
- Cysts and tumors
- Stones
- Changes due to infections
- Obstructions
- Fluid collection
Preparing for Renal Ultrasound and what to expect during the exam
Proper preparation is a critical point in your renal ultrasound. Your urinary bladder should be full for this exam. You should finish drinking 32 ounces (four glasses) of water one hour before your examination time. Please, keep your bladder full till the ultrasound. After the sonographer assesses and measures your bladder they let you empty it completely and measure again in order to see your ability to empty it.
After Your Kidney Ultrasound Exam
The radiologist will make a written report and forward it to your referring doctor in two business days. Your doctor will call you to discuss the results, usually within two-three days. In an emergency, results are available in 2 hours.

Can a renal ultrasound detect kidney stones?
Kidney stones can be detected via ultrasound. Ultrasound is the modality of choice for pregnant patients with flank pain. Sometimes, CT scan,and urine tests are needed to confirm the diagnosis.
Does renal ultrasound help to diagnose UTI (Urinary Tract Infection)?
UTI is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra.Women are at greater risk of developing a UTI than are men since their urethra is shorter. Infection limited to your bladder can be painful and annoying. However, serious consequences can occur if a UTI spreads to your kidneys.Urinary tract infections don't always cause signs and symptoms, but when they do they may include:
- A strong, persistent urge to urinate even when the bladder is empty
- A burning sensation when urinating
- Passing frequent, small amounts of urine
- Passing urine that appears cloudy
- Pelvic pain, in women — especially in the center of the pelvis and around the area of the pubic bone
A UTI is generally diagnosed with a urine test and culture, but ultrasound helps detect if there is an anatomical reason for a UTI (stone, narrowing), and in rare occasions it can also distinguish if the urge to urinate and passing a small amount of urine is due to the inability to urinate or because of a UTI.
Are there any risks with a renal ultrasound?
A renal ultrasound is a safe procedure that uses sound waves, so there is no risk associated since no radiation is used.
