Abstract
The aim of the study was to determine Monarc (American Medical Systems) sling position after surgical treatment of stress urinary incontinence (SUI) through the transobturator approach. A total of 54 consecutive women with SUI were evaluated post-operatively with transvaginal ultrasound. A concomitant hysterectomy was performed in ten cases and a concomitant prolapse surgery in six cases. Ultrasound measurements include urethral length, the distance between the upper edge of the sling and the bladder neck (BN–S) and the BN–S/U ratio. The mean distance between the transobturator tape and the bladder neck was found to be 12.6 ± 3.2 mm in the group of patients who underwent the transobturator procedure alone, 13 ± 3.1 mm in the transobturator plus hysterectomy group and 12 ± 2.8 mm in the transobturator plus prolapse group. The superior tape margin was at the mid-urethra in 81.5% of patients and always at a distance greater than 7 mm from the bladder neck. Eight patients did not have satisfactory results after the surgery. Only in one out of these eight patients was the transobturator sling not found to be at the mid-urethra. The superior tape margin of the Monarc sling remained at the level of mid-urethra in the majority of cases. It was never located too proximally beneath the bladder neck.
