title: Clinical evaluation of urethral tumors based on a simple classification system.
abstract: A simplified classification for primary urethral tumors is proposed. The T stage for tumors of male or female and of the upper or lower urethra has been combined into a single system. The system has been applied to 104 cases of urethral tumors. Although the cases were not necessarily very well qualified, a retrospective survival study demonstrated a general trend to a poorer prognosis in higher stages. Such a unified system might be useful for a simple classification of urethral tumors, a rare neoplasm with various clinical manifestations depending on sex or tumor site.
