Surgical treatment of SUI Laparoscopic colposuspension Open retropubic colposuspension Suburethral slings Tension free vaginal tape Transobturator foramen tape Anterior vaginal repair (anterior colporraphy) Needle suspension
Cochrane DB, NICE guidelines, ICS guidelines Open retropubic colposuspension may be more likely to cure stress incontinence compared with anterior vaginal repair at 1-5 years. Complication rates are similar to those with other surgical procedures, but are higher than with non-surgical treatments. Suburethral slings, tension free vaginal tape (TVT), transobturator foramen procedures (TOT, TVT-O), and needle suspension may be as effective as open retropubic colposuspension in curing stress incontinence over 5 years. Complications of tension free vaginal tape include bladder perforation. Laparascopic colposuspension seems to be as effective over 5 years as open retropubic colposuspension or tension free vaginal tape. Cochrane DB, NICE guidelines, ICS guidelines
TVT golden standard by proving same effectiveness as colposuspension TVT became golden standard for SUI surgery in women after proving the same effectiveness as colposuspension. The study by Ward and Hilton was a milestone for TVT.

Analysis of TVT operation at the Obstetrics and Gynaecology Clinic of LUHS
Objectives Estimate the results and complications of TVT and TVT-O procedures
Study design A prospective study using a standardized preoperative and postoperative protocol
Material TVT operation TVT-O operation TVT Exact operation 114 women were operated and followed up during study period: 25 02 2000 – 01 07 2006 TVT-O operation 307 women were operated and followed up during study period: 20 03 2006 – 01 05 2011 TVT Exact operation 16 women were operated and followed up during study period: 03 01 2011 – 01 04 2011
Inclusion criteria All patients had typical medical history of stress incontinence The degree of the incontinence was 2-3 according to Ingelman-Sundberg scale Patients with urge symptoms were treated preoperatively with anticholinergics and HRT
Methods A medical history and urinary diary was taken of the duration and the severity of the stress incontinence A gynecological examination was performed A stress provocative test was performed in the supine and standing positions with a comfortably filled bladder (300ml) before and post operation A quality of life evaluation was undertaken
Methods II Urodynamic evaluation was performed by clinical indications for 30% of patients Foley catheter was left for 24 h after TVT operation and 6 h after TVT-O operation. The postoperative evaluation included operation time, complications, hospital stay and postoperative evaluation after 1 year was carried out.

Conclusions TVT and TVT-O operations are very effective procedures while curing female stress incontinence after 12 months of follow-up. TVT-O procedure has a shorter operation time and hospital stay. TVT-O had lower complications rate that TVT procedure. TVT Exact operation had 50% complications, but effectiveness after 2 months was 100%.
