Kidney Stone Tests & Diagnosis
When patients have severe abdominal pain, doctors often use one or more of the following tests to determine if kidney stones are present. They also determine how large the stones are, where they are located and if they are causing damage to the urinary tract.
Computed Tomography (CT): This imaging scan is the preferred test for diagnosing kidney stone. It allows the doctor to see an image of the kidneys and the ureters (the tubes connecting the kidney and bladder).
Intravenous Pyelogram (IVP): This type of X-ray allows your doctor to see the size, shape and position of the urinary tract, including the kidneys and ureters. It is performed by injecting a dye into an IV so your doctor to more clearly visualize the area.
Retrograde Pyelogram: A procedure similar to IVP, the dye is instead injected directly into the ureters.
Urinalysis and/or Urine Cultures: Taking a sample of the patient’s urine, testing is performed to determine the presence of stones.
Ultrasound: Another imaging option, this procedure often is performed if you are pregnant.
History and Exam: Your doctor asks you about his/her medical history, diet and lifestyle.
Stone Analysis: Your doctor may ask you to collect the stone as it passes (using a special strainer device). Once the stone is collected, it can be analyzed to determine its type.
Blood and Urine Tests: Blood and urine samples are taken and analyzed to help determine the type of stone and the chance for future kidney stones
Once the team has determined the presence of kidney stones and the type of stones present, they will develop a treatment plan. and may create a plan for prevention of future kidney stones.
