and Boney test, supine stress test, and urination diary, 24-hour pad test, cystoscopy and urodymanics measurements (cystometry and Valsalva leak point pressure) were recorded for each patient. The patients filled out ICIQ-SF and Korman questionnaires for urinary incontinence.The data of the patients and the success of the operation were evaluated based on 24hr pad test, ICIQ-SF scoring,and Korman questionnaire analysis. Results: The mean age of the patients was 49.7 ± 8.7 years (range: 31-75 years). None of the patients suffered intraoperational complications. In all of the patients, the postoperative 6th,12th, and 48th months ICIQ-SF scores, pad counts and pad test were reached to the statistically significant lower than those of the preoperative period (p<0.05)Postoperatively, in the 48th month, 135 patients (93.75%) had continence rate and the patient satisfaction rates for all patients were as 125 patients (86.8%). Four patients (2.77%) had vaginal extrusion, and 2 patients (1.38%) had urethral extrusion. Four patients (2.77%) had suture granuloma and ten patients (6.94%) had de novo urgency. Discussion: Broad based double forced sling is an effective technique in the treatment of stress urinary incontinence and type of the mesh used in sling surgery is very critical point and further clinical and experimental studies are needed.
