Common Procedures

If your child will be having the following tests done, it may be helpful for you and/or your child to know what to expect:

  • Urine Test- Patients with urinary complaints might have to give a urine specimen for testing. The patient will void in a cup during the clinic visit. Please ensure that the patient has a full bladder when arriving to the clinic and ask for a specimen cup as needed if the child needs to urinate before his/her appointment.
  • VCUG - (voiding cysto urethrogram): This is a bladder test that is done by placing a small tube in the bladder through the urethra. The bladder is filled with an X-ray dye.
  • Ultrasound: This is a non-invasive test that allows visualization of the bladder and kidneys. Sound waves are sent through the patient's body and the results give 2D images of the urinary tract. This test takes about 20 minutes.
  • DMSA Scan: This is a test that is used to determine kidney function. A special tracer is injected through an IV and when injected will light up the kidney. The results of this test show areas of kidney infection or kidney damage. This test takes about one hour.
  • Renogram: This is a similar test to a DMSA scan, except it also allows us to determine if there is any blockage. The tracer is put into the urine and can be followed as it goes down into the bladder. In patients who have any blockage or obstruction in the urinary tract, the test shows that the tracer does not drain. This test can take up to an hour and a half.
  • KUB: this is a simple x-ray of the kidneys, ureters, and bladder. This test is usually done to find kidney stones or severe constipation.
  • Post Void Residual (PVR): this is a quick scan of the bladder right after the patient has emptied the bladder. This test is used to show us if there is any urine remaining in the bladder. This test is usually performed in the exam room in clinic.

  • Uroflow: This is a study used to determine the flow rate of your urine during voiding. This test is sometimes done to look for the cause of incomplete bladder emptying, slow stream, burning with urination, bladder pain, or other symptoms. To learn more about this test, click on the "Specialty Clinics" tab on the left and go to "Urodynamics".

  • Urodynamics: This study is used to assesses how the bladder and urethra are performing their job of storing and releasing urine. Urodynamic tests help your doctor see how well your bladder and sphincter muscles work. To learn more about this test, click on the "Specialty Clinics" tab on the left and go to "Urodynamics".
