Twelve months effect on voiding function of retropubic compared with outside-in and inside-out transobturator midurethral slings

Introduction and hypothesis The purpose of this study is to compare retropubic tension-free vaginal tape (TVT) with transobturator out-in TOT and in-out TVT-O for female stress urinary incontinence. Uroflow rate was primary; continence rates, quality of life (QoL) and complication pattern were secondary endpoints. Methods A prospective randomised trial with 2:1:1 randomisation at two Swiss teaching hospitals. Patients were followed up at 12 months. Results Eighty TVT, 40 transobturator tape (TOT) and 40 TVT-O were randomised. At 12 months, there was no difference in Qmax among the groups. Continence was comparable (≥89%). QoL was improved significantly in all groups ( P
