ABSTRACT BACKGROUND AND OBJECTIVES Urinary tract infections and the presence of stones in the urinary tract are common diseases among people . Many factors caused urinary tract infections and urinary tract stones. to prevent and even treat the disease early, screening in each area can be helpful. MATERIALS AND METHODS In this study, 370 urine samples from the Noorabad region of Lorestan were analyzed in terms of biochemistry, microbiology and, microscopy. Culture media and subtractive tests were used to detect the type of contaminating bacteria. RESULTS AND DISCUSSION Finally, by analyzing the data, 21.35% of people were involved in urinary infection, which included Gramnegative bacteria, Escherichia coli (73.4%), Klebsiella (10.5%), Citrobacter (5.7%), and Gram-positive bacteria. They included Staphylococcus (7.3%) and Enterobacter (3.1%). The most common type of bacteria found was Escherichia coli. Also, 11.89% of people showed urinary crystal excretion, and the most common type of crystals observed were calcium oxalate (79.54%), amorphous urea (11.42%), amorphous phosphate (6.81%) and uric acid (2.27%). The total number of urine leukocytes and the total number of bacteria in the urine samples were higher in women than in men. The number of leukocytes and the presence of crystals were related to the presence of bacteria and this relationship was signicant for all two factors (p<0.05). CONCLUSION Bacterial infection was more in women than men and the most important reason of infection was Escherichia coli. The crystalluria was not different in men and women, and calcium oxalate was most important crystal in samples. Bacterial infection and the presence of crystals were not related to age.
