Abstract：Objective To explore the clinical characteristics of after percutaneous nephrolithotomy in middle-aged and elderly female patients with upper urinary tract calculi of Hani Yi nationality in the Red River Basin.Methods 392 cases with upper urinary tract calculi after percutaneous nephrolithotomy treated by Department of Urology,the Fifth Affiliated Hospital of Kunming Medical University/Diannan Central Hospital of Honghe Prefecture from July 2013 to September 2016 were retrospectively analyzed.Middle urine bacterial culture performed in all patients before surgery, bacterial culture was conducted inrenal pelvis urineand collected calculi during operation and blood bacterial culture was added for patients with acute systemic inflammatory response syndrome after operation.The positive rate of a variety of culture result was counted.Incidence rate of systemic inflammatory response syndrome in middle-aged and elderly female and male group,young boys and girls group was respectively compared.Drug resistant strain of urinary tract infection after operation and antibiotic susceptibility of common pathogens in middle-aged and elderly female patients was analyzed.Results The incidence rate of systemic inflammatory response syndrome after percutaneous nephrolithotomy in middle-aged and elderly female patients(36.4%) of Hani Yi nationality was obviously higher than that of middle-aged and elderly male patients(17.1%)and young boys and girls group(12.7%),and there was astatistical difference(χ2=9.144,P=0.002;χ2=24.255,P<0.01).Among the strains isolated from the population,the population carrying multiple drug resistant strains accounted for 58.7%,among them,the middle-aged and elderly female women were as high as 75.0%.The main pathogens of Gram negative bacteria,and antibiotic resistance was highforpenicillins,quinolones and cephalosporins and it was sensitive to compound beta lactamase inhibitors,Amikacin,Imipenem and so on.Conclusion Infection rate of urinary tract infectionafter percutaneous nephrolithotomy in middle-aged and elderly female patients of Hani Yi nationality in the Red River Basinis high,and multiple drug resistant bacteria infection is more common,and it should be paid attention to.
