title: Pattern of urolithiasis in Brooklyn, New York.
abstract: Crystallographic analysis of 261 upper urinary tract calculi from patients in Brooklyn is presented. Calcium oxalate, uric acid, and struvite stones predominate. We could not confirm the hypothesis that uric acid forms a nidus in calcium oxalate urolithiasis in spite of a percentage of uric acid calculi more than twice the national average.
