NONAbstract
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 .
