Abstract:
Objective To discuss the risk factor of infection after intracavity lithotripsy in upper urinary tract calculi,and establish a pre-operation warming score system.Methods From Jan.2013 to May 2016,412 upper urinary calculi patients who underwent intracavity lithotripsy were analyzed to evaluate the associated risk factors before operation and infection after operationg by non-conditional logistic regression analysis.The pre-operation warming score system was established by giving those risk factor 1-4 point based on OR value.The best threshold was then determined by ROC curve.Results Diabetes mellitus,infection history,renal calculus and uretero-pelvic junction calculus,stone burden,the degree of hydronephrosis and the gender of female were high-risk factors contributed to infection after intracavity lithotripsy,which were given 3,3,3,2,2,2point respectively based on their OR value(8.660,7.046,3.723,2.675,2.256,1.891),and the patients who got high socre were more likely to suffered infection.The sensitivity and specificity of the wanning score system for infection after intracavity lithotripsy were 74.3％ and 84.0％ respectively when its truncation point was 7.5 point(total score was 15 piont).Conclusions Patients who got more than 7.5 point according to the wanning score system were high risk groups of infection after intracavity lithotripsy.
