22403 Calculi Analysis

Calculi Analysis
Test Code: MISC
Synonyms/Keywords
​Stone Analysis, Renal Stone Analysis
Useful For
​Analysis of urinary calculi is an essential step in the examination and initial treatment of the patient with kidney stones (urolithiasis). Knowledge of the composition of calculi yields fundamental information concerning the pathogenesis of the disease, including metabolic abnormalities, presence of infection, possible artifacts, and even drug metabolism. Our report to the physician notes the weight, size, and shape of stones, the constituents of the stone and their order of deposition, the presence of a nidus and its composition, the presence of foreign bodies or artifacts, and the presence and identification of unusual components, such as drugs and drug metabolites. The need for specific analysis increases as progress is made in treating various forms of urolithiasis and as interrelationships among predisposing factors become evident.
