title: [Modelling longitudinal ureteroplasty in children].
abstract: On the basis of their personal experience acquired in the total of 29 modelling interventions in the ureters of 16 children, the authors discuss the value, the technique and the indications of modelling longitudinal ureteroplasties--or the Hendren operation. This intervention was performed in 8 patients for secondary megaureter, and in another 8 patients it was performed for primary megaureters. When it was necessary modelling was performed simultaneously on both sides. In patients without previous derivations systematic use was made of ureter splintering after modelling--when it was re-implanted. Some technical details are discussed. The authors stress the necessity to know exactly before the intervention, the true functional value of the kidney the ureter of which will undergo modelling. Otherwise inutile modelling interventions will be performed (one case). In 3 of the patients, at 4--6 months after surgery, modelling of the upper segment of the ureter was necessary, together with pyeloplastia. The series analysed confirmed the value of this technique aimed at direct correction of the large dilatations of the ureters.
