Brief summary

This project will assess the success (cure rate) of two types of suburethral sling procedures in the treatment of women with urodynamic stress incontinence and intrinsic sphincter deficiency. This group of patients has a low urethral closure pressure and is a challenging subgroup of patients that has shown less success in their treatment with other surgical methods (e.g. Burch colposuspension). The suburethral sling procedures (e.g. TVT) have shown better results in this group. The Monarc sling is a new procedure that places the tape in a different way (through the obturator foramen) as the TVT, which has been established for some time in the treatment of intrinsic sphincter deficiency. Therefore we will assess and compare the success and other outcomes (complication rate, hospital stay, etc) of both procedures.

Interventions

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.
