title: [Inverted carcinoma of kidney pelvis coexisting with transitional cell carcinoma of the bladder. A therapeutic alternative].
abstract: OBJECTIVE
  To describe a case of inverted carcinoma of the right renal pelvis associated with transitional cell carcinoma of the bladder. The unusual nature of this condition and the incidence of tumor recurrence in some patients with bladder cancer and, at least initially, no histopathological evidence of infiltrating tumor prompted us to report this case.
  
  
  RESULTS
  A 65-year-old male consulted for prostatism. Several months earlier he had had an episode of hematuria. The difficulty in making the diagnosis is underscored and the possibility of conservative surgical management is discussed. Tumor recurrence at two sites distinct from that of the bladder tumor warranted TUR. Two years after the first surgical procedure the patient is disease-free.
  
  
  CONCLUSIONS
  Like most authors, we usually perform radical surgery in these cases. However, in the case described herein, the difficulty in making the diagnosis prompted us to use a conservative approach which, at the present time, appears to have been effective for the renal tumor. New treatment options, like endourological surgery, may have an important place in the management of this tumor type in carefully selected cases.
