title: [Cystic pyeloureteritis. A diagnosis to keep in mind].
abstract: OBJECTIVE
  Cystic pyeloureteritis is a disease entity of unknown etiology and unspecific symptoms. It is incidentally detected and is difficult to distinguish from other disorders showing filling defects on urographic evaluation. All the foregoing prompted us to report the present case.
  
  
  RESULTS
  We report a case of cystic pyeloureteritis that had been diagnosed during ureterorenoscopy in a patient with lithiasis and recurrent urinary tract infection. The etiopathogenesis, diagnostic and therapeutic aspects described in the literature are briefly reviewed.
  
  
  CONCLUSIONS
  We underscore the importance of confirming the diagnosis by endoscopic and cytological studies. Conservative management is advocated. Patient follow up should include urinalysis, urine culture and cytology twice yearly and intravenous urography once a year.
