Abstract | ||||
Background: The correlation between stone disease and bacteria was restricted to the association with struvite stones. Few studies shed light on the association between bacterial infection and non-infectious stones. Objective: To identify the bacteria isolated from preoperative urine, pelvic and urine kidney stone samples. Methods: Fifty preoperative urine, pelvic and urine kidney stone samples were collected from nephrolithiasis patients. The stones̕ chemical composition was tested by Fourier-transform infrared spectroscopy (FTIR). The three type of samples were subjected to microbiological analysis. Results: The 50 patients consisted of 22 males and 28 females. The mean age of the patients was 48.7±14. The most common type of stone was uric acid in 27 (45%). s.aureus was the most predominant pathogen in stone and pelvic urine samples with 7 (35%) and 4 (66.6), respectively. E-coli was the most common pathogen in the preoperative bladder urine with 7 (50%). Conclusion: Gram-positive bacteria were the predominant pathogen associated with stone and pelvic urine. The preoperative urine culture did not reflect the upper urinary tract infection. | ||||
