摘要: Objective To investigate the correlation between urinary calculi and upper urinary tract infections.Methods Twenty-six patients underwent lithiasis in upper urinary tract accompanied with infectious symptoms were enrolled in this study (test group).Blood culture was obtained in peak temperature before lithotrity,urine sample was obtained for bacterial culture.Thirty patients with calculi in upper urinary react accompanied no infectious symptoms in the same period were enrolled in control group.Calculi were pestled for bacterial culture and analyzed the components after the calculi were removed.Results In test group,the positive of blood,urine,calculi culture were 4,23,18 patients.The prominent component of calculi was hexahydrate magnesium ammonium phosphate.Bacteria in 13 positive urine sample had the same property with the calculi samples which came from the same cases.In control group,the positive of urine,calculi culture were 4,4 patients.The prominent component of calculi were calcium oxalate calculi and uricite calculi.The morbidity of upper urinary tract infections in test group was significantly higher than that in control group [69.2％(18/26) vs.13.3％(4/30)] (P ＜ 0.05).The coincidence of urine culture and calculi culture in test group was significantly higher than that in control group [72.2％(13/18) vs.25.0％(1/4)](P＜0.05).Conclusions Infectious calculi can easily result in upper urinary tract infections.Hexahydrate magnesium ammonium phosphate can make the prominent component in infectious calculi.
