Kidney Ureteral Stones

Metabolic Evaluation

Metabolic evaluation kidney ureteral stones

If you have a high risk of forming more stones (See Causes of Kidney and Ureteral Stones), your doctor will do a metabolic evaluation. This is a series of blood and urine tests to determine which additional treatment you may need.

Depending on the test results, you may get medication. Generally, the medication will cause little or no side effects. In addition, it may be helpful to consider lifestyle changes (See Prevention of Stone Recurrence). Your doctor will discuss your individual situation and treatment options with you.

As part of the metabolic evaluation your doctor will ask you to collect your urine in 2 separate periods of 24 hours. This is done some 3 weeks after your stone has passed or has been removed. The amount of urine is measured and so are the levels of different substances in the urine.

Interesting Fact

Urine substances include calcium, magnesium, oxalate, and uric acid.

Two to three months after you start medication, the doctor will take another urine sample to check if the dosage should be adjusted. For a large part, treatment depends on the kind of stone you had.
