[Urodynamic findings in females following urinary incontinence operations. I: Anterior colporrhaphy (author's transl)].

In a retrospective study the effect of anterior colporrhaphy (mainly combined with vaginal hysterectomy) was analyzed using urodynamic and clinical data which were available in each patient before and after the operation. Two main samples were chosen: 106 patients with complete relief after the intervention (group I) and 43 women with recurrent incontinence (group II). Functional urethral length and maximum closure pressure were not significantly influenced by this operative procedure. However, in women belonging to group I--i.e. successfully treated--the urodynamic findings showed a clear tendency to more favourable values when compared with patients suffering from recurrent incontinence (alpha < 0,025). Our data indicate that urodynamic analysis of each patient before any vaginal operative procedures seems to be of clinical value to quantitate the success-rate of vaginal repair; patients with an unusual short urethra and low maximum closure pressure are not expected to be continent after anterior colporrhaphy.
