Tension-free vaginal tape and autologous rectus fascia pubovaginal sling for the treatment of urinary stress incontinence: a medium-term follow-up.Med Princ Pract. 2008; 17(3):209-14.MP
To compare two different procedures, tension-free vaginal tape (TVT) and autologous rectus fascia sling, according to their medium-term subjective and objective outcomes and satisfaction rates in the treatment of urinary stress incontinence in women.
SUBJECTS AND METHODS
One hundred women with type II urinary stress incontinence were randomized to be treated with either TVT or autologous rectus fascia sling. They were evaluated by means of a cough-induced stress test, 1-hour pad test, Incontinence Impact Questionnaire (IIQ), and urodynamic study. They were reevaluated postoperatively every 6 months, and the collected data of more than 1 year's follow-up were compared with preoperative assessments.
All patients completed the full 6-month postoperative assessment. However, of the 100 patients, only 61 (25 in the TVT and 36 in the sling group) were followed for more than 1 year. Mean follow-up time was 38.5 and 40 months in the TVT and sling group, respectively. Objective cure was achieved in 22 (88%) of the TVT group and in 30 (83%) of the sling group (p = 0.78) using a cough-induced stress test, and in 76 and 75% of the women in the TVT versus sling group (p = 0.83), respectively, using a 1-hour pad test. Postoperative mean IIQ scores were 44.3 (range 35.5-61.5) and 48.5 (range 38.5-69.7) in the TVT versus sling group (p = 0.46). Five (20%) and 11 (30%) of the TVT and sling group, respectively, reported some changes in the voiding pattern or posture at more than 1 year's follow-up.
There is no significant difference between the TVT and autologous rectus fascia sling procedures in the treatment of urinary stress incontinence at medium-term follow-up. There were changes in the voiding pattern for patients in both groups at more than 1 year postoperatively, which were not evident at early follow-up.
