Abstract

Decisive for urethral closure under stress is an increase in intraurethral pressure. This pressure increase is significantly affected by urethral tonus, passive pressure transmission and reflex pressure transmission. Approximately half of the urethral tonus is produced by the striated sphincter muscles (Rud et al. 1981; Tanagho 1979).
