Objective: To evaluate the clinical factors that influence the outcome of endoscopically treated primary grade III and IV vesicoureteral reflux (VUR).

Materials And Methods: Excluding secondary VUR and patients with incomplete follow up, a retrospective and prospective cohort observational study was performed on 90 children (130 renal units) with primary grade III or IV reflux treated endoscopically with Polytef or Macroplastique from March 1997 to January 2004. All patients underwent voiding cystourethrography (or galactose-based sonocystourethrography), dimercaptosuccinic acid (DMSA) scan, renal ultrasound and clinical exploration of micturition.
