[Clinical significance of profilometry of the pyeloureteral segment in congenital hydronephrosis in children]. / Klinicheskoe znazhenie profilometrii pieloreteral'nogo segmenta pri vrozhdennom gidronefroze u detei.

Examination of hydrodynamic condition of the upper urinary tracts with step-by-step pyelomanometry and profilometry of the pyeloureteral segment in 26 children at the age of 6 to 14 years with hydronephrosis provided topical diagnosis of the obstruction level. The priority role of the pelvis in development of obstructive urodynamic disorders was ascertained in 9 children. In the rest 17 children urodynamic disorders were determined by a different degree of obstruction in the prepelvic ureter. This urodynamic study may be essential for design of new approaches to choice of treatment method in the context of pathogenesis of hydronephrosis development.
