Kidney Stones Diagnosis (Cont.)

 
CT Scan or IVP
The doctor may decide to scan the urinary system using a special test called a CT (computed tomography) scan or an IVP (intravenous pyelogram). The results of these tests can help determine the proper treatment for kidney stones.
 

Urine Collection Test and Kidney Stones Diagnosis

Patients may be asked to collect their urine for 24 hours after a stone has passed or been removed. The sample will be used to measure:
 
  • Urine volume
  • Levels of acidity
  • Levels of calcium
  • Levels of sodium
  • Levels of uric acid
  • Levels of oxalate
  • Levels of citrate
  • Levels of creatinine (a product of muscle metabolism).
 
Your doctor will use this information to determine the cause of your kidney stones, and a second 24-hour urine collection may be needed to determine whether the prescribed treatment is working.
