['To evaluate the effectiveness and safety of the ambulatory, minimally invasive tension-free vaginal tape procedure in women scheduled for incontinence surgery.', 'A prospective open study with a standardised protocol for pre- and post-operative evaluation.', 'One hundred and sixty-one consecutive women with urodynamically proven stress incontinence. The mean age was 56 years; 45 women (28%) had recurrent incontinence, 59 women (37%) had mixed incontinence and 18 women (11%) had a low pressure urethra.', 'Subjective and objective cure rates, complications and length of hospital stay.', 'The average follow up time was 16 months. Ninety-four percent of the treated women were completely cured or significantly improved. Eighty percent of the women were released from hospital on the afternoon of the day of surgery. There were no major complications and 80.2% of the women had no complication at all. Seven women (4.3%) had no more than four days of urinary retention problems, five women (3.1%) developed de novo urge symptoms, ten women (6.1%) had urinary tract infection, six cases (3.7%) of intraoperative bladder perforation occurred and less than 3% had bleeding or infection problems. There was no difference in the cure rate between women suffering from primary, recurrent or mixed incontinence.'] Is the tension-free vaginal tape procedure successful in the majority of women with indications for surgical treatment of urinary stress incontinence?
