title: [Evidence-based medicine in urology].
abstract: The quality of a therapeutic trial depends on several parameters. The ideal trial in prostate cancer should be a high-quality trial on a well-defined and significant population. The method used to calculate the number of subjects necessary should appear in the study. There should be a single and significant evaluation criterion and follow-up should be long given the natural history of the disease. Intention to treat is also a quality terion. Finally, the therapeutic class effect does not exist; therefore, the efficacy of inoma any new drug must be proven.
