A STUDY ON BACTERIA ASSOCIATED WITH KIDNEY STONE

Abstract

Result of studying 110 calculi taken from 110 patients showed that the male(80) more affected than females(30), the age group was the most affected followed by age group (31-40) yrs. It also showed that (74) patients with acid urine were having crystalluria , except for (18) patients with alkaline urine and (16) patients had pyuria .Calcium calculi made the greatest constitution of calculi in proportion of (76.35%) while uric acid calculi were only (9.09%). Infection stone made (14.53%) of the total renal stone. Males were the most affected with stone, whereas females were prevalent with infection stone. Five bacterial species were isolated from of all stone comprised the following: Pseudomonas aeruginosa ,E.coli ,Staphylococcus aureus ,Klebsiella pnemmoniae ,and Proteus mirabilis.However, Pseudomonas aeruginosa was making the greatest proportion (43.47%)of the total stone number, while (88) stones did not yield a growth of any bacteria .All bacterial isolates were multi-drug resistant ,generally Nitrofurantion, Nalidixic acid, Cephotaxime, etracyclin, and Rifampicin, while Ampicilline, Amoxicillin, Cefalotine, and Gentamicin were the most efficient in inhibiting bacterial growth .
