title: [Papillary renal carcinoma presenting as hydronephrosis].
abstract: BACKGROUND
  We describe a new case of incidental renal papillary carcinoma. We perform a bibliographic review.
  
  
  METHODS
  The papillary renal cell carcinoma is a variant of renal carcinoma. They classify in two subtypes that have relation with their prognosis. We presented one case of renal papillary carcinoma in a male of 76 years, play-acting as severe hydronephrosis.
  
  
  RESULTS
  We describe the findings and final pathological result associated with a synchronic metastasis in the ipsilateral ureter.
  
  
  CONCLUSIONS
  We describe the findings and final pathological result associated with a synchronic metastasis in the ipsilateral ureter.
