Detection and Resistance Analysis of Postoperative Pyeloid Pathogens in Elderly Patients with Urinary Stones
Objective:To analyze the detection and resistance of pyeluria pathogens in elderly patients with urinary calculi.Methods:The clinical data of 92 patients admitted to our hospital from January 2021 to August 2023 were included in the detection of pyeluria pathogens,and the resistance test and drug resistance results were analyzed.Results:A total of 87 strains of pathogenic bacteria were cultured from 92 patients with urinary calculi after operation.Among them,Gram-negative strains were the main ones,and Escherichia coli,Klebsiella pneumoniae and Pseudomonas aeruginosa were the main Gram-negative strains.Gram-positive bacteria were mainly Enterococcus faecalis and Enterococcus faecium.According to the drug resistance test,Escherichia coli,Pseudomonas aeruginosa and Klebsiella pneumoniae in Gram-negative bacteria were highly resistant to moxifloxacin,ciprofloxacin,amoxicillin,piperacillin,ampicillin,ticarcillin and compound sulfamethoxazole.The resistance rates of Enterococcus faecalis and Enterococcus faecium to oxacillin,penicillin,ampicillin and gentamicin were higher in Gram-positive bacteria.Conclusion:Gram-negative bacteria are the main pathogenic bacteria causing postoperative infection in elderly urinary calculi,monitoring their distribution,drug resistance and rational drug use.
