[Improvement of methods of surgical correction of congenital hydronephrosis in children].

The analysis of the authors' own results of surgical treatment for hydrohephrosis in 81 children after the Anderson-Haines-Kucher has revealed that the most common complication is stenosis of the anastomosis made. The authors' modified operation has indicated that the use of a less traumatic access to the pelvioureteral portion, of optic magnification, a microsurgical instrument, 7/0 synthetic suture material, drainage of the renal collecting system with a pyelostomic tube of original design allows the optimal conditions to be created for formation of the pelvioureteral anastomosis and the good results of hydronephrosis treatment to be obtained in children.
