Published: May 20, 2024
Uric acid stones can be tricky to diagnose. Learn the tests doctors use to identify these stones and guide treatment.
The Role of CT Scans
CT scans are the gold standard for diagnosing uric acid stones. They can detect stones that are invisible on regular X-rays. This test is quick and doesn't require contrast, making it a preferred choice for many doctors.
Analyzing Passed Stones
If a stone is passed naturally, chemical analysis can determine its composition. Knowing whether a stone is made of uric acid or another substance helps guide treatment. This analysis can be crucial for preventing future stones.
24-Hour Urine Collection
A 24-hour urine test can help identify risk factors for stone formation. It measures urine pH and uric acid levels, providing valuable information for treatment plans. Though not always necessary, it can be helpful in recurrent cases.
