[Urodynamic findings in women after surgery for stress incontinence: urethrovesical suspension according to Pereyra (author's transl)].

The effect of the urethrovesical suspension according to Pereyra (combined with vaginal repair and hysterectomy) was analyzed using urodynamic and clinical data of 30 stressincontinent women before and 1 year after the operation. Parameters of 149 patients also suffering from stress incontinence treated by anterior colporrhaphy were studied in a similar way. The comparison showed that women with an unusual short urethra ( less than 22 mm) and a low urethral closure pressure (less than 45 cm H2O) are not expected to be continent after anterior colporrhaphy. In these cases the Pereyra suspension could be indicated to reduce the risk of recurrent incontinence.
