Naumann 2006.

Methods	RCT of classic TVT tape by Gynecare compared with LIFT by Cousin Biotech, with the distinctive feature of a suburethral pad (assumed to be inserted as classic TVT)
Participants	254 women with SUI
Interventions	Group A: TVT (n = 123) Group B: LIFT (n = 125)
Outcomes	Subjective cure or improvement: assessed with VAS Subjective evaluation of QoL Objective cure: evaluation of preoperative and postoperative urodynamic measurements, or results of a pad or clinical stress test Subjective cure, 6 months and 12 months Subjective cure or improvement, 6 months and 12 months Bladder perforation Excess bleeding Need for division of tape Tape erosion into bladder or urethra Vaginal mesh erosion
Notes	Follow‐up 12 months LIFT is a woven monofilament polypropylene tape that can be passed through the transobturator and also the retropubic routes The study seemed to compare the 2 tapes (TVT and LIFT), which have similar characteristics and were both passed through the retropubic routes
