The authors attempt to assess success of surgery in 44 women with stress incontinence treated with colporrhaphia ant. et post. with/without vaginal hysterectomy, by evaluating preoperative and postoperative findings. Examination comprised, after detailed anamnesis, besides general gynaecological examination and examination of urine for pathological constituents, the following methods: simultaneous urethrocystometry, cystometry, urethrocystography, electromyography of the sphincter system, as well as uroflowmetry. It was found that despite subjectively reported success of operation there was often no direct correlation to the actual, objective findings. This underlines once again that assessment of the result of surgery is possible only via application of a wide range of diagnostic procedures postoperatively with the same methods. The results obtained are discussed with reference to reports published in medical literature.
