[ОPTIMIZATION OF EXAMINATION ALGORITHM FOR PATIENTS BEFORE AND AFTER OPERATIVE INTERVENTION FOR HYDRONEPHROSIS]

Algorithm of the patients examination, suffering hydronephrosis, caused by obstruction of different etiology, was optimized, what permitted, using qualification of rational volume and sequence of diagnostic methods, owing high sensitivity and specificity, as well as morphological diagnostic coefficients (parenchymal—stromal, dysbalance of collagens) and the risk criterion for recurrence occurrence, to estimate renal structure— functional state, to determine the disease stage, its course severity and to substantiate a volume and duration of preoperative preparation needed, the operative intervention kind and postoperative management of the patients.
