This paper includes the preoperative, early (i.e. half a year) and late postoperative (on average 3.8 years) clinical, urodynamic and morphological findings of 145 stress incontinent women. An anterior vaginal repair was performed in 54 patients, while 91 received urethrovaginal fixation according to Burch. Early postoperative analysis of urodynamic parameters shows deterioration in the vaginal repair group and improvement of the colposuspension group. Comparison of early and late postoperative urodynamic findings indicates gradual deterioration as a function of time. Morphological findings prove that the abdominal operation elevated and attached the bladder neck better and more durably to the symphysis pubis, even though late postoperative examinations show impairment of these results with time. Follow-up showed that in the early postoperative period 91% of patients with urethrovaginal fixation were cured or improved, while the success rate for the vaginal repair was 76%; late postoperative results revealed 89% and 86% cure or improvement rates respectively. The results confirm that the success of operative repair is highly dependent on the selection of the correct procedure by proper preoperative diagnostic evaluation.
