Aim - to report the results of the ureteroneocystostomy in the treatment of the obstructive complications of the vesicoureteral reflux (VUR) endoscopic correction in children.
Materials and methods. The results of intra- and extravesical open ureteroneocystostomy (UCNS) variants (6 and 6 cases, respectively) in the treatment of the obstructive complications of the vesicoureteal reflux endoscopic correction were analyzed in 12 children (5 boys, 7 girls, aged 2- 8 yrs. In all cases UO was unilateral. The ultrasonographic (US) data and the results jf the intravenous pyelography (IVP) was considered as UO parameters. The renospecific enzymes activity levels (N-acetyl-β-D-glucosaminidase - NAG, its termostable isoform NAG B and β-galactosidase (β-Gal) were utilized as markers of kidney function deterioration degree. All mentioned above markers analyzed before and 6 months after surgery.
Results. In all 12 cases surgeries were performed successfully with no intraoperative or postoperative complications. The significant decrease in upper urinary tract dilation, increased parenchyma thickness were estimated as well as the renospecific enzymes activity levels in 6 months.
Conclusions. UCNS is a reliable technique in ureteral patency restoration in secondary UO after vesicoureteral reflux endoscopic correction in children. The lesser bladder trauma is considered to be the advantage in extravesical surgery.
The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of all participating institutions. The informed consent of the patient was obtained for conducting the studies.
