Boston2018 post-market clinical study is a prospective, randomized, non-inferiority study to assess the efficacy and adverse events of the Solyx™ Single Incision Sling (SIS) System compared to the gold-standard Obtryx™ II Sling System, in patients with stress urinary incontinence (SUI) and long-term follow-up (5 years).
Randomized prospective non-inferiority study, in which we evaluate patients with stress urinary incontinence (SUI) who undergo surgical treatment consisting of a minimal incision in the suburethral area of the vaginal mucosa for a mesh insertion in order to:
Main Objective:
To compare the continence rate (objective) between Solyx and Obtryx II meshes in patients with SUI. This rate will be determined by an effort test.
Secondary Objectives:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| S (SOLYX) | Experimental | The Solyx™SIS System is an innovative mid-urethral sling single incision system consisting of a 9 cm long polypropylene mesh, whose mid-urethral portion (4 cm) is detanged to potentially resist deformation and to reduce irritation to the urethral wall. Snap-fit to delivery device tip allows for advanced placement control and, therefore, the tensioning through the forward and reverse functions performed with this delivery device. |
|
| O (OBTRYX II) | Experimental | The Obtryx II System (Halo) is a transobturator sling designed to allow inter-operative adjustability with minimal tissue disruption. It consists of two delivery devices (one patient right and one patient left) and one mesh assembly. The mesh assembly is comprised of a polypropylene knitted mesh with dilator legs and a center tab. At the distal ends of the dilator legs there are association loops designed to be placed in the needle slot of the distal end of the delivery device. The disposable delivery device consists of a handle with a stainless steel needle. The needle is designed to facilitate the passage of the mesh assembly through bodily tissues for placement through the obturator foramen. |

| Pad test |
1 hour pad test: After a spontaneous urination the patient will place a compress that will be weighed previously. After, the patient has to drink a half liter of water in 15 minutes sitting. Between the minute 15 to 45 has to walk and / or go up / down stairs. From minute 45-60 the patient has to get up and sit 10 times, cough 10 times, run 1 minute, lift an object from the ground 10 times and washes his/her hands 1 minute. According to the difference in weight of the compress, it will be cataloged as follows: ≤ 1 gram -> continent. 1.1-9.9 grams -> mild incontinence. 10-49.9 grams -> moderate incontinence. > 50 grams -> severe incontinence |
| Month 1, month 6, year 1, year 2, year 3, year 4 and year 5. |
