FEATURES OF REGRESSION OF CONGENITAL HYDRONEPHROSIS IN THE LONG PERIOD AFTER SURGERY IN CHILDREN

Abstract

The features of regression of congenital hydronephrosis were studied depending on its stage and follow-up period in the long-term period after corrective plastic surgery in the area of ​​the ureteropelvic segment in 81 children, aged from 1 to 14 years, with stages I, II and III of congenital hydronephrosis with one ( 53) and on both sides (28), without postoperative complications. In patients with stage I congenital hydronephrosis 3-6 months after surgery, there was a rapid regression of congenital hydronephrosis. The renal cortical index has completely returned to normal, while in patients with stage II congenital hydronephrosis, the tendency to regression slows down sharply. A decrease in the renal-cortical index to normal values ​​was observed only after 1-2 years. In stage III congenital hydronephrosis, the renal-cortical index in the long-term period decreases by no more than 40%, and after 3 years by 50% compared with the preoperative period. In no case in stage III congenital hydronephrosis did we notice a reduction in the size of the pelvicalyceal system to a level corresponding to a healthy organ, regardless of the timing of the operation. Comparative studies of congenital hydronephrosis before and in the long-term period after surgery showed that the degree and intensity of the reduction in the size of the pelvicalyceal system was the higher, the smaller its initial dimensions were. The data obtained indicate the need for early diagnosis of congenital hydronephrosis and the implementation of surgical corrections in the early stages of the disease.
