About

Prospective, single-arm, non-sponsored, observational single centre trial in a cohort of patients undergoing stress urinary incontinence surgery with ALTIS® procedure. All patients were diagnosed according to clinical reports, physical exploration and urodynamics. Body mass index(BMI) was categorized according to World Health Organization classification. Valsalva leak point pressure was categorized in three groups <60 cmH2O, 60-90 cmH2O and >90 cmH2O). Participants were evaluated post-operatively at 1, 6, 12 and 24 months with physical examination, ICIQ-SF, visual scale of satisfaction(SVS)(0-10). Adverse events were reported in each visit. Multivariate analysis for risk factors of surgery failure was performed.

Full description

This is a prospective, single -arm, non-sponsored observational single centre trial in a cohort of patients undergoing stress urinary incontinence surgery with ALTIS® procedure. Two urologists, experts in female incontinence surgery, performed all procedures. Safety and efficacy were evaluated. All participants provided written informed consent prior to enrolment.

The investigators recruited female patients aged 35 years or more with urodynamically proven stress urinary incontinence and who had failed to 6 months of non-surgical therapies including behavioural changes and drug therapy. Exclusion criteria were pelvic infection, pelvic organ prolapse ≥Stage 2, prior stress urinary incontinence surgery, neurogenic bladder incontinence, previous pelvic radiotherapy, high post-voiding volume (100 mL in two times) or being pregnant.

Demographic variables (age, number of vaginal deliveries, prior stress urinary incontinence surgery, menopause status, BMI and presence of urge incontinence) were collected. BMI was categorized according to World Health Organization in normal (18,5-24,9 Kg/m2), overweight (25-29,9 Kg/m2) and obese (≥ 30 Kg/m2) patients. For statistical purpose the investigators divided patients into two groups, non-obese (18,5-29,9) Kg/m2) and obese (≥ 30 Kg/m2) patients.

Preoperative assessment included urogynecological history, cough test (stress test with at least 300 mL of bladder volume measured by ultrasound), Spanish validated version of the International Consultation on Incontinence Questionnaire sort form (ICIQ-SF) and urodynamic test (Urodynamic parameters as Valsalva leak point pressure (VLPP), non-inhibited detrusor contractions and post-voiding volume were reflected. VLPP was categorized into three groups <60 cmH2O, 60-90 cmH2O and >90 cmH2O).

Follow up was carried out with physical examination, ICIQ-SF, visual scale of satisfaction and physical examination including cough test. Subjects were evaluated post-operatively at 1, 6, 12 and 24 months. Adverse events, such as vaginal erosion or pain related to the procedure or the device were evaluated at each visit.

The primary efficacy measures were objective cure, defined as negative cough test, and subjective cure, defined as ICIQ-SF=0.
