Use of suspended catheters (stents) during surgery of hydronephrosis in children

: The application of hanging catheters (stents) in operations for hydronephrosis in children has considerable advantages over classical (open) methods of drainage. Bacteriological investigations of analyses of urea performed in open and closed closed systems of drainage have shown less incidence of infection of the upper urinary tracts with intrahospital gram-negative flora after operation on patients operated upon with using stents, which gave less amount of postoperative complications.
