Transvaginal mesh is a surgical net-like implant, manufactured by various companies such as Ethicon, C.R. Bard, American Medical Systems, Boston Scientific, Coloplast, Cook Medical, Neomedic. It is used in the form of a sling to treat Stress urinary incontinence (SUI) and Pelvic organ prolapse (POP) in women since the 1990s. Abdominal hernias have also been treated with a surgical mesh since the 1950s. The insertion of this mesh or a bladder sling through the vagina is known as a transvaginal mesh. The Food and Drug Administration (FDA) approved the first surgical mesh specifically designed for SUI in 1996. Later, in 2004, FDA approved the first surgical mesh specifically for use in POP.
Analysis of the market data by the manufacturers points out that as of 2010, a mesh was used in one out of three POP surgeries. Moreover, a transvaginal mesh was used in over 80% of the SUI surgeries.
Popular bladder slings are the following types:
Tension-free vaginal tape (TVT): TVT is a polypropylene mesh tape that is placed under the urethra and the patient’s body holds it in place.
Transobturator tape (TOT): This is less invasive than TVT because there is no need to use a large needle when inserting it.
Mini-sling: Through an incision in the vagina, a mesh tape is placed with the help of a metallic inserter that safely avoids the need for any incisions in the abdomen.
