Summary:When urinary tract infections (UTIs) preexist, in terms of composition the calculi can contain magnesium ammonium phosphate, variable amounts of calcium, cystine, calcium oxalate monohydrate or uric acid. The preoperative uroculture was negative in 106 patients and positive in 54 cases According to Moores O'Boyle classification, the stones were: 53 type A, 21 type B, 56 type C and 30 type D. After PCNL, stone fragments were analyzed identifying a number of 47 infectious calculi and 113 metabolic lithiasis (calcium carbonate, oxalate, phosphates, uric acid). Type A and C (Moores O'Boyle classification) staghorn stones were the most frequent, predominantly with a mixed structure containing variable proportions of calcium carbonate, oxalate, phosphates, uric acid and for the most part of the cases without being accompanied by urinary tract infections.
