The objective of this study is to evaluate the efficacy and morbidity of the new minimally invasive TVT-secur procedure. This was a prospective multi-centre trial. All patients with primary urodynamic stress urinary incontinence were prospectively selected to receive the TVT-secur procedure. The International Consultation on Incontinence-Short Form (ICIQ-SF), Women Irritative Prostate Symptoms Score (W-IPSS), Patient Global Impression of Severity (PGI-S) and Patient Global Impression of Improvement (PGI-I) questionnaires were used to evaluate the impact of incontinence and voiding dysfunction on quality of life (QoL) and to measure patient's perception of incontinence severity and improvement. The SPSS software was used for data analysis. From November 2006 to September 2007, 95 consecutive patients were enrolled in the study. At 1 year, 91 patients were available for the analysis. The subjective and objective cure rates were 78% and 81%, respectively. The ICIQ-SF and W-IPSS symptoms score showed a statistically significant decrease. Post-operative complications included voiding difficulty, recurrent UTI, de novo urgency incontinence and dyspareunia. Our data show that TVT-secur is associated with an 80% success rate at 1 year.
