title: [Complex vesicoureteral reflux. Our experience].
abstract: OBJECTIVE
  To analize the proportion of complex reflux in the whole amount of patients treated endoscopically of vesicoureteral reflux in our hospital. To determine the endoscopic treatment success in complex reflux, and the influence of reflux grade in it.
  
  
  METHODS
  We present our experience between 1992 and 2003 with three kinds of substances (polytetrafluoroethylene, polydimethylsiloxane and dextranomer-hyaluronic acid copolymer). We treated complex reflux in 74 patients with endoscopic injection. All patients were scheduled to have voiding cystourethrogram 3 and 9 moths after injection. A positive response was defined as grade 0 or I reflux.
  
  
  RESULTS
  Reflux was solved using the endoscopic procedure in 86.25% after first injection, 93.75% after second and 96.25% after third. The corresponding results for reflux grade II, III and IV were 88.9%, 83.3% and 100%.
  
  
  CONCLUSIONS
  We conclude that subureteral injection of different sustances (Teflon, Macroplastique or Deflux) is a useful treatment for most cases of vesicoureteral reflux. We propose it as first step of treatment.
