ABSTRACT
<p><b>OBJECTIVES</b>To analyze the pathogenic bacterial's distribution and the drug resistance in the upper urinary tract stones, and to provide the information for choosing suitable antibiotics.</p><p><b>METHODS</b>Stone samples were taken for culture and for drug sensitivity test in 146 patients undergoing percutaneous nephrolithotomy between April 2007 and October 2008, and the results were analyzed.</p><p><b>RESULTS</b>Pathogens presented in 72 (49.3%) patients. There were 70 (86.4%) Gram-negative bacteria strains. Escherichia coli, Pseudomonas aeruginosa and Enterobacter cloacae were the predominant bacteria, accounted for 30.9%(25 strains), 23.5% (19 strains) and 12.3% (10 strains), respectively. There were 10 (12.3%) Gram-positive bacteria strains, the predominant bacteria was Staphylococcus epidermidis (6 strains), accounting for 7.4%. And there was 1 fungi strain (1.2%). Resistance to ampicillin/sulbactam (88.7%), ceftriaxone (81.3%) and ciprofloxacin (67.5%) was most commonly found in pathogen, and the rate of resistance to amikacin, imipenem and piperacillin/tazobactam were 8.6%, 10.0%, 10.0%, respectively. Erythromycylamine, teicoplanin, SMZ-TMP, nitrofurantoin were sensitive to Gram-positive bacteria.</p><p><b>CONCLUSIONS</b>Bacterial's distribution of upper urinary tract stones are multiple, and the majority pathogen is Gram-negative bacteria. A big variant resistance is found among different bacterium. The suitable antibiotics should be chosen according to the different bacterium in the patients who underwent percutaneous nephrolithotomy.</p>
