  • Title: Successful colposuspension in stress urinary incontinence reduces bladder neck mobility and increases pressure transmission to the urethra.
    Author: Penttinen J, Lindholm EL, Käär K, Kauppila A.
    Journal: Arch Gynecol Obstet; 1989; 244(4):233-8. PubMed ID: 2782951.
    Abstract:
    Twenty-nine consecutive patients with stress urinary incontinence were investigated by bead chain urethrocystography (UCG) and single cough urethrocystometry before operation and 8-12 months after a Burch colposuspension producing clinical improvement. The operation significantly elevated the bladder neck and reduced its mobility during acute stress. The urethral inclination angle and the posterior urethrovesical angle also became smaller at rest and on straining. A significant negative correlation was found between the postoperative mobility of the bladder neck and the post-operative pressure transmission ratio (PTR), indicating that correction of the urethrovesical anatomical disorder eliminates the functional disorder in this disease and restores continence.
