Objective: Report a case of a synchronous bilateral urothelial carcinoma of the upper urinary tract without bladder affectation.
Methods: We describe the diagnosis and treatment of a case of a bilateral upper urothelial carcinoma.
Conclusions: Synchronous bilateral urithelial carcinoma of the upper urinary tract without bladder affectation in an unusual occurance (1-5% of urothelial tumors) and radical surgery continues to be the treatment of choice, although it is possible to take a less aggressive approuch with selected groups of patient, in which we can achiese a survival rate similar to that which we obtain with radical surgery.
