METHOD FOR PREDICTING EFFICIENCY litholytic THERAPY IN ureteral stones

摘要

A method for predicting the effectiveness of therapy for litholytic ureteral calculi on the basis of fuzzy decision logic, characterized in that the composition dictionary informative signs, symptoms include 8, subjects are divided into two classes: ω- shown litholytic therapy, ω- contraindicated litholytic therapy comprising, calculated for each of the 8 characteristic values ​​accessories functions to these classes, synthesized a group of highly qualified specialists under the direction of engineer knowledge Is calculated confidence coefficients iterative rule inference with the determination to the above classes, the final output defuzzification method is determined by comparing the obtained values ​​with the threshold confidence coefficients equal, with formation of a clear O: IF (KU≥0,6) AND (KU 0, 6), then [ "expedient execution litholytic therapy"] ELSE [ "inappropriate execution litholytic therapy"].
