In approximately 25-40% of @entity1 presenting with @entity340 ( @entity340 ) @entity177 will develop before adolescence. In some these @entity1 , @entity8 , @entity1494 and mismanagement may precipitate @entity177 at even earlier age. The goals of this study were to determine whether long-term @entity1494 was more frequent in @entity1 who underwent early temporary pyelostomy than in those who underwent valve ablation, and to know if @entity1494 and mismanagement, in some @entity1 , could be responsible of early @entity177 . Urodynamic studies were performed in 59 @entity1 with severe @entity340 divided into two groups based on initial treatment. A) Valve ablation (30 p.); B) Cutaneous pyeloureterostomy (29 p.). At the end of the study 22 @entity1 had @entity177 . Of the 59 @entity1 , 42% (25 p.) had bladders with overdistended or normal behaviour, 58% (34 p.) had @entity1494 (instability 37%, low compliance 15%, myogenic failure 5%). The 89% of low compliance bladders, 66% of myogenic failure and 23% of those with instability were in @entity6192 . No difference at all was found in bladder function between @entity1 treated as neonates by high diversion or valve ablation. Of the group in @entity177 (22 p.), only 7 @entity1 (32%) had bladders with normal behaviour and in five of these @entity1 a mismanagement was directly related with a quicker @entity177 . The 58% of our @entity1 with severe @entity340 have some type of @entity1494 . Neonatal pyelo-ureterostomy does not increase long-term @entity1494 . Surgical mismanagement should be added to @entity1494 as contributors to earlier @entity177 .
