[Choice of a drainage method in plastic reconstructive operations for congenital hydronephrosis in boys].

We analysed surgical outcomes in 41 boys aged 2.5 months to 17 years with congenital hydrohephrosis who were treated with external drainage (nephrostoma, intubation drainage, Gibbon's drainage) and by means of stenting. We discovered that stent drainage produces urethral traumas, orchitis, orchoepididymitis. Our study made us to recommend external drainage methods for boys with congenital hydronephrosis undergoing reconstructive plastic surgery to prevent injuries and inflammation in the urogenital system.
