Five-year follow-up study of Monarc transobturator tape for surgical treatment of primary stress urinary incontinence

INTRODUCTION AND HYPOTHESIS: We hypothesized that transobturator tape (TOT) is safe and efficacious for the treatment of urodynamic stress incontinence in the long term.

METHODS: We conducted a prospective study of patients with confirmed urodynamic stress incontinence (USI) who underwent a Monarc(TM) TOT procedure in a tertiary center between February 2006 and March 2009 without other concurrent surgical procedures. Urodynamics were conducted at 1 and 3 years postoperatively. Subjective evaluation included Incontinence Impact Questionnaire (IIQ-7), Urinary Distress Inventory Questionnaire (UDI-6), and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Objective cure was defined as no urinary leakage demonstrable on provocative filling cystometry and/ or 1-h pad test of <2 g. Subjective cure was based on a negative response to question 3 in UDI-6. Paired-samples t test, chi-square, and Fisher exact tests were applied; p
