Abstract
Introduction
TVT-Secur (TVT-S) was the first single-incision sling available on the market and was soon found to have less efficacy than mid-urethral slings. Our aim was to assess the position and tape descent following TVT-O and TVT-S H in a U procedure and, based on this evaluation, to find the possible reason for lower TVT-S surgery efficacy.
Methods
We conducted an ultrasound study of a randomised trial with a 3-year follow-up that took place between 2007 and 2009 and included 197 women with urodynamic stress urinary incontinence. Of these, 67 were allocated to receive the TVT-O procedure, 64 to TVT-S in the H position, and 65 in the U position. Patients underwent a complete urogynaecological and ultrasound examination. The positions of the bladder neck and the tape after surgery were assessed and the data obtained compared between groups.
Results
Our primary study showed a significantly higher rate of positive stress tests in the TVT-S groups compared to the TVT-O group. After surgery, there was no difference between the position of the tape at rest and at maximal Valsalva between the groups. In TVT-O patients, the mean length of the upper tape margin descent increased from 6 mm on the 1st day after surgery to 9 mm 3 months after surgery and remained stable afterwards. For TVT-S patients, there was a further increase of up to 15 mm in tape descent after 3 months.
Conclusions
Our results show that the lower efficacy of TVT-S might be due to inadequate fixation and increasing tape descent.
