title: Secondary hydronephrosis to polyarteritis nodosa.
abstract: A case of secondary hydronephrosis to lesions from polyarteritis nodosa localized in a short segment of the mid-portion of the ureter together with sclerolipomatosis, periureteritis and functional stenosis is presented. Polyarteritis nodosa is a necrotizing vasculitis affecting small and middle-sized arteries of all organs but more particularly the kidney, heart, gastrointestinal tract, testicles, liver and the striad muscles. Localization in the fatty tissue surrounding the ureter with a periureteritis is not frequent, only 1 case has been published in the literature (1).
