Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Insertion of tension free vaginal tape (retropubic sling), trans-obturator suburethral sling. Surgery for sling insertion takes 15-20 minutes, theatre session time varies due to commonly performed concommitant prolapse surgery. The study has a 3 year follow up period after surgery was performed.
Intervention code [1] 2572 0
Treatment: Surgery
Comparator / control treatment
Monarc transobturator tape/tension free vaginal tape
Both treatments are suburethral sling procedure used in the treatment of stress urinary incontinence. The TVT tension free vaginal tape is the tape procedure that has been used the longest (since 1996) while the obturator tape is a newer technique requiring further evaluation/ and comparison with the established TVT
