ABSTRACT
The organs of the male and female urinary tracts and the male genital tract represent two composite biological systems which are readily described in their anatomical relationships and their physiological functions. In the clinical reality of urological practice, these broad descriptions must be narrowed to suit the physically constricted world of surgical anatomy and the, necessarily narrow, application of surgical physiology. In the operating theatre, the standard textbooks of human anatomy and physiology are sometimes relevant.
