Brief Summary
Introduction: Minimally invasive procedures TOT (tension-free suburethral tape using transobturator approach)have been the standard for correction of SUI. However, around 28% of these patients exhibit alteration of urinary flow. Recently, in 40 patients who underwent open surgery, an abdominal fascia tape was placed in a subtrigonal position with a success rate of 87.5% without obstruction. Our intention is to make the most of the idea of subtrigonal position in minimally invasive procedures with transobturator polypropylene vaginal tape (S-TOT). Object of the Study: To evaluate the efficacy and security of S-TOT compared with TOT. Materials and Methods: Study Population: Patients of the Mexican Institute of Social Security (IMSS) with an SUI diagnosis. Eligibility requirements: history of at least 3 months with symptoms of isolated SUI or symptoms of SUI associated with urge urinary incontinence (mixed UI). The size of the sample was estimated 34 subjects are required per group. Study Design: It is a parallel group randomized clinical trial. Success (efficacy) will be defined as when the SUI has been corrected with negative pad test and normal urinary flow. The results (efficacy) will be compared between the two groups using chi2 (group a/b versus success/lack of success). In all cases, p \<0.05 will be considered significant. The data will be obtained with clinical evaluation, laboratory and radiological/imaging tests and the respective questionnaires during the visits before surgery, and at 2 and 6 weeks, and 6, 12, and 24 months after surgery.

Outcome Measures
Primary Outcomes (1)
Stress urinary incontinence resolution, without postoperative obstruction
Resolution of SUI: Negative 1/h pad test and regular urination (without change or obstruction in the Blaivas Nomogram and/or the Female Urinary Symptom Score). Negative pad test, \<3g/1 hours. -Postoperative Obstruction: Female Urinary Symptom Score (FUSS): 1-7 points = mild obstruction, 8-18 = moderate obstruction, and \>19 = severe obstruction AND/ OR Ascending change in the level of obstruction provided that there is an increase of ≥ 5 points compared to the baseline AND/ OR Qmax: ≤20ml/s, provided there is a reduction compared to the baseline AND/ OR Blaivas Nomogram: The intersection of Qmax (abscissa) and maximum contraction of the detrusor (ordinate) will fall in one of four possible areas: not obstructed, mild obstruction, moderate obstruction or severe obstruction

Interventions
Minimally invasive surgery for placement of suburethral polypropylene tape (TOT), which is widely used around the world and considered the standard of treatment at present, has very limited efficacy when considering the correction of SUI without affecting normal micturition. There is evidence that the placement of autologous fascia tape in subtrigonal position has higher efficacy. Thus, the subtrigonal placement of polypropylene mesh tape through minimally invasive procedures could have higher efficacy.
Minimally invasive procedures in which needles are inserted via transobturator approach for the placement in mid-urethral position of polypropylene tape that is 1.5cm wide for the treatment of SUI
