[Pyeloureteral stenosis secondary to Schoenlein-Henoch purpura].

We present an 8-year-old male suffering from Schönlein-Henoch purpura with multisystemic clinical manifestations, which developed as a complication a pyeloureteral stenosis secondary to vasculitis. He was operated on and a ureteropyeloanastomosis was carried out according to the Anderson-Hynes technique with good results. We discuss the etiology, diagnostic methods and therapeutic possibilities. It is the eighth case in the literature requiring surgical correction as a result of this exceptional complication.
