Recent randomized trials and studies with long-term follow-up have indicated that TVT procedure is safe and effective for the treatment of stress UI. In a randomized controlled study (n = 72), Paraiso et al (2004) concluded that the TVT procedure results in greater objective and subjective cure rates for urodynamic SUI than does laparoscopic Burch colposuspension. This is in agreement with the results those by Valpas et al (2004) and Ward et al (2004). In a multi-center randomized controlled trial (n = 128), Valpas and associates reported that treatment with TVT results in higher objective and subjective cure rates at 1 year than treatment by means of laparoscopic mesh colposuspension. In another multi-center randomized controlled study (n = 344), Ward and colleagues concluded that the TVT procedure appears to be as effective as colposuspension for the treatment of urodynamic stress UI at 2 years.
