title: [Anterograde endopyelotomy].
abstract: OBJECTIVE
  To analyze the results obtained with antegrade endopyelotomy and compare them with those reported in the literature.
  
  
  METHODS
  16 patients with ureteropelvic junction (UPJ) obstruction treated by antegrade endopyelotomy were evaluated.
  
  
  RESULTS
  In our series the success rate was 81.3%. Avulsion of the UPJ was observed in one patient and required conversion into an Anderson-Hynes pyeloplasty. Two cases of re-stenosis were diagnosed within the first three months.
  
  
  CONCLUSIONS
  Long-term follow-up shows that antegrade endopyelotomy can be indicated as the treatment of choice for primary and secondary UPJ strictures.
