[Urodynamic parameters before and following a vaginal incontinence operation].

We compared two groups of patients 14 months after vaginal hysterectomy and pelvic floor repair, group I (n = 20) postoperatively continent versus group II (n = 27) postoperatively incontinent. Preoperative urodynamic findings were of no prognostic value with regard to continence. There was no statistical difference in maximum resting urethral closure pressure (UCP), urethral functional length and dynamic and reflectoric vesico-urethral transmission factor, in spite of group I having a slightly higher resting UCP than group II. Group II showed a significant decrease of resting UCP postoperatively.
