[Functional results following transobturator and retropubic mid-urethral sling]

To compare functional results following retropubic and transobturator mid-urethral sling procedures.

Multicenter randomized controlled trial. Power calculation was based on the rate of bladder injury. The current study concerns an analysis of secondary judgment criteria.

One hundred and forty-nine patients were randomly allocated to either TVT (n=75) or TVT-O (n=74). Among them, 132 women completed a 24-month follow-up. There was no significant difference between the two groups, concerning urodynamics data (excluding uroflowmetry) at 12 months follow-up, functional and sexual results at 6, 12 and 24 months follow-up. Concerning sexual results, an improvement in visual analogue scale scores was observed in both groups at 24 months follow-up with no difference between the two groups: median score increased from 70 (IQR: 50-80) pre-operatively to 90 (IQR: 70-100) at 24 months follow-up (P=0,0004) in TVT-O group and from 70 (IQR: 50-80) to 85 (IQR: 70-100) (P=0,0009) in TVT group.

TVT and TVT-O procedures are both associated with an increase in quality of life with no significant differences in functional results at 2 years follow-up.
