title: [Intraureterocele transitional tumor synchronous with contralateral ureteral tumor: obstructive uropathy in panurothelial disease].
abstract: OBJECTIVE
  To present a case of urothelial tumor inside a simple ureterocele with a coexisting contralateral tumor that caused bilateral obstructive uropathy.
  
  
  METHODS
  Follow-up evaluation of a 74-year-old male patient with superficial tumor of the urinary bladder diagnosed 4 years earlier, revealed renal failure and bilateral obstructive uropathy. The complementary tests showed a simple left ureterocele containing a lesion suggestive of a tumor and a right ureteral tumor.
  
  
  RESULTS
  After biopsy confirmed coexisting urothelial disease at 3 levels (intraureterocele, contralateral ureter and in situ carcinoma of the bladder), the patient was submitted to cystoprostatectomy, nephroureterectomy and en bloc segmental ureterectomy.
  
  
  CONCLUSIONS
  Multicentric synchronous urothelial tumors warrant a close and long follow-up of the entire urinary tract. Among the possible sites of presentation, few cases of tumors inside a ureterocele have been reported. The case described herein, with this uncommon site of presentation, is an example of panurothelial disease.
