Primary Outcome Measures:
  • Cure rate [ Time Frame: 6 months postoperative ]
    The primary outcome of the TOT procedure will be assessed using a combination of objective and subjective criteria. Patients with a negative stress test, a negative 1-h pad test (less than 2 g) and the degree of subjective suffering improving to over 90% (VAS score of 0-1) at 6 months follow-up evaluation are classified as cured. All other patients are classified as treatment failure even if one aspect shows marked improvement from the preoperative condition.


Secondary Outcome Measures:
  • Urethral length [ Time Frame: Preoperative ]
    Urethral length will be measured by pelvic floor sonography.

  • Linear urethral dorsocaudal movement (LUDM) [ Time Frame: Preoperative ]
    Linear urethral dorsocaudal movement (LUDM) will be assessed by pelvic floor sonography.

  • Urethral tape position [ Time Frame: 1-3 days and 6 months postoperative ]
    The position of the TOT along the urethra will be determined by pelvic floor sonography and expressed as percentage of urethral length.

  • Distance between tape and longitudinal smooth muscle (LSM) complex [ Time Frame: 1-3 days and 6 months postoperative ]
    To characterize the location of the TOT, the shortest distance between the tape and the longitudinal smooth muscle (LSM) complex of the urethra will be measured by pelvic floor sonography.

  • Urodynamic testing [ Time Frame: Preoperative ]
    Urodynamic testing will be performed only for patients undergoing recurrent incontinence surgery.

Detailed Description:
This is a prospective, observational, multicenter study of women with surgically-correctable stress urinary incontinence who undergo a TOT-sling operative procedure. Data will be collected from preoperative urogynecological testing and medical histories. Outcome data will be collected 1-3 days and 6 months after procedure.
