The role of bladder instability in pathogenesis of stress-incontinence in women
After having held urodynamic examination of 700 women complaining of stress-incontinence 292 cases of bladder instability were revealed. Bladder instability is characterized by spontaneous or provoked detrusor reactions of hypertensive type. They appear involuntarily and are followed with simultaneous urethra relaxation. Heavy increase of intravesical pressure along with the decrease of obturative one under physical stress may lead to urine loss in case of abnormal transmission of increased intraperitoneal pressure impulse. Forming of functional cystourethral funnel and relaxation of urethral cross-striated sphincter cause these disturbances. Bladder instability may lead to the development of stress incontinence or complicate its running.
