Determine stone composition, risk factors, and optimal treatment

The presence of stones within kidneys, or nephrolithiasis, is the most common condition affecting the urinary system.¹ Kidney stones correlate with an increased risk of chronic kidney disease, end-stage renal failure, cardiovascular diseases, diabetes, and hypertension.

To optimize patient care, our kidney stone services will identify the physical compositions of stones. Mayo Clinic Laboratories’ comprehensive approach and concise report supports your practice with accurate interpretation to guide clinical decisions.

Guiding patient therapy

Mayo Clinic Laboratories’ kidney stone analysis evaluates the urinary stones’ crystalline complexes for insights that can be useful to facilitate treatment decisions. Knowledge of stone composition is particularly useful for individuals with recurrent stone formation.

Key testing

When to consider testing

• After first collected stone.
• After subsequent stones, depending on the clinical situation.
• In conjunction with a metabolic evaluation.
