title: [Bilateral hydronephrosis with papillary polypoid cystitis].
abstract: OBJECTIVE
  A case of papillary polypoid cystitis with bilateral hydronephrosis and an intravesical mass is presented.
  
  
  RESULTS
  A routine ultrasound evaluation performed in a 64-year-old diabetic female revealed an intravesical mass and bilateral hydronephrosis. There was extensive bladder involvement and the ureteral orifices could not be visualized during endoscopy. Transurethral resection of the lesion was performed. The histological examination showed papillary polypoid cystitis. The urinary cultures were positive, antibiotic therapy was instituted and the hydronephrosis, disappeared.
  
  
  CONCLUSIONS
  Papillary polypoid cystitis, although a benign and superficial lesion, can be diffuse, involve both ureteral orifices and cause hydronephrosis.
