| Objective:To explore a economical, simple and effective measure that can ensure the safety of upper tract calculus complicated with pyonephrosis patients with the first stage mini-percutaneous nephrostolithotomy, and also reduce the number of operations, lighten the burden of patients.Methods:This was a prospective trial of group control study, the trial of the patients who undergoing first stage mPCNL between December2011and April2013in xiangya hospital of central-south university. and the patients must correspond with group measure. The patients are divided into The experimental group and The control group. The experimental group was patients with pyonephrosis are flushed with dilute complexing iodine; The control group was the common patients. Compare two groups of patients with postoperative fever (routine blood、degree of fever、days of fever)、culture results of puncture fluid after washing、hospital stays of postoperation. The first two results were mainly compared. The data was analyzed by SPSS19.0.Results:Fifty-one patients in this topic were performed mPCNL successfully, twety-two patients were diagnosed pyonephrosis during operation and then accepted the first stage mini-percutaneous nephrolithotomy after flushed with dilute complexing iodine, There were twenty-nine patients in the control group. In experimental group, the cultivate results of punctured fluid before and after flushed were statistical significance(by chi-square test, p<0.05), the averaged postoperative fever days of experimental group were1.52±0.59days,The control group were1.00±1.01days, there were no statistical significance(by one-factor analysis of variance,p>0.05), the postoperative leukocyte of experimental group were9.05±2.95(*10^9/L) and the control group were8.68±2.81(*10^9/L), there were no statistical significance(by one-factor analysis of variance,p>0.05), the postoperative neutrophils ratio of experimental group were83.65±9.83%and the control group were86.04±7.87%, there were no statistical significance(by one-factor analysis of variance,p>0.05), The average length of hospital stay after surgery in experimental group were8.84±0.37days and the control group were8.14±1.82days, also there were no statistical significance(by one-factor analysis of variance, p>0.05).Conclusion:Patients with intraoperative biopsy diagnosed with pyonephrosis were safe and reliable that accepted the first stage mPCNL after flushed with dilute complexing iodine, The postoperative complications rarely appeared, Patients recovered quickly. |
