Triamterene calculus.
Triamterene therapy is an unusual cause of nephrolithiasis and, when this agent is found in a stone, generally it is deposited in minor amounts. We report a renal calculus consisting mostly of triamterene and its 2 major metabolites in a patient taking a triamterene-containing drug, and discuss some implications.
