A Randomized Controlled Study Comparing Three Single-incision Devices for Female Urinary Stress Incontinence

Phase 4
Completed
Conditions
Urinary Incontinence
Interventions
Procedure: Ajust positioning
Procedure: MiniArc positioning
Procedure: TVT secur system positioning
Procedure: Tension free vaginal ttape
Registration Number
NCT00751088
Lead Sponsor
University Magna Graecia
Brief Summary

The prevalence of urinary stress incontinence in middle age women is rated at about 30%. To date, there is an increasing use in the clinical practice of new techniques for the treatment of this condition and several surgical devices, characterized by minimally invasive approach, are commercialized.

Recently, single-incision devices have been proposed. One of the most relevant potential advantages of these devices is the possibility of performing their positioning under local anesthesia, thus, in ambulatory regimen. The employment of these devices is particularly useful in two subgroups of patients with urinary incontinence, i.e. women with genuine stress incontinence not associated to pelvic organ prolapse (POP) and women whose stress incontinence raised after surgical correction of (severe) POP.

Poor data coming from randomized controlled trials (RCTs) are available regarding single-incision devices for the treatment of stress incontinence, and there are no conclusions in terms of their feasibility, efficacy and safety. Finally, to our knowledge no randomized controlled trial is actually available in literature comparing different single-incision devices.

Detailed Description

Women with genuine urinary stress incontinence not associated with POP will be enrolled and randomized in three groups (arm 1, arm 2 and arm 3). All patients eligible will undergo baseline assessment consisting of anthropometric, clinical, hormonal, ultrasonographic and urodynamic evaluations. At time of surgery, all patients will be randomized in three surgical treatment groups (arm 1, 2 and 3). Patients of arm 1 will be treated with positioning of Ajust (Bard Urological Division, Covington, GA, USA), patients of group 2 will be treated with positioning of MiniArc (AMS, Minnetonka, MN, USA) and patients of arm 3 will be treated with positioning of TVT Secur System (Ethicon, Somerville, NJ, USA).

During the study, the clinical outcomes, and the adverse experience will be evaluated in each patient.

Data will be analyzed using the intention-to-treat principle and a P value of 0.05 or less will be considered significant.
