AbstractThe current study involved isolation and identification of bacteria from (50) urine samples of patients suffering from renal stones and urinary tract infections (UTIs) Sixteen bacterial isolates were obtained from urine samples (32%), Proteus mirabilis and Escherichia coli being the most frequent among isolates, forming 37.5% (6 isolates) and 31.5% (5 isolates) respectively while Klebsiella pneumoniae isolates 12.5% (2 isolates) then Enterobacter aerogenes, Pseudomonas aeruginosa, Staphylococcus aureus were isolated at a rate of (6.25%).
The study showed that 32 (64%) of urine samples were from patients having calcium stone, 10 (20%) with uric acid stone and 8 (16%) with struvite stone but cystine stones were not identified. Furthermore, this study showed that there is a relationship between type of stones and the type of bacterial isolate .
The effects of some factors such as sex and age on the rate of infection with different stone types were investigated ,the results revealed that among (32) calcium stones, 71.9% were males and 28.1% were females. From (8) struvite stones, males represent 37.5% while females were 62.5%, for uric acid stone 60% were males and 40% were female.
The incidence of renal stone seem to be the highest in the age group(30_53) years comprising 48% of the total patients followed by the age group (54_77) years 32% and the least incidence was in the age group (6_29) years 20% .
