Minimally invasive methods for the treatment of obstructive ureterohydronephrosis in children

Abstract

Purpose of the study . To evaluate the effectiveness of minimally invasive methods of treatment in children with congenital obstructive ureterohydronephrosis. Material and research methods . We performed ureteral stenting in 78 (70.9%) children with congenital obstructive ureterohydronephrosis: I degree of ureterohydronephrosis -18 (23.0%), II degree -34 (43.6%) and III degree. -19 (24.3%), IV degree -7(9.0%). Children under the age of 16. Children with impaired urodynamics in the distal ureters underwent a complete clinical-biochemical laboratory and X-ray study. Results of the study and their discussion . Stenting of the ureters was carried out in order to dynamically monitor the contraction of the urinary system. In children, stenting is performed under general anesthesia by performing cystoscopy. After assessing the topographic location of the orifice from the side of the pathology of the vesicoureteral segment, the ureteral orifice is expanded by balloon dilatation, followed by stenting of the ureter. It turned out to be effective in 26 (23.6%) children. Conclusions . With neuromuscular dysplasia of the ureters in children of the first year of life, bougienage, balloon dilation of the ureterovesical fistula, followed by stenting of the ureter and pyelocaliceal system in 34.0% of patients lead to a significant improvement in urodynamics.
