blot as much urine up as you can- if it's still wet (doesn't matter) mix vinegar & water in a spray bottle (40/60 or any strong combo will do)- soak entire area. let sit a while then coat with baking soda- let sit again. scrub with hand brush- take up with paper towels.
Hernia mesh is a product which is used in hernia repair. It is made from implant-grade plastics which are formed into a grid which can be used at the site of a hernia to hold herniated organs in place and provide a lattice for new tissue to grow on, effecting a long term repair at the site.
Surgical mesh is also widely used in hernia repairs and to treat stress incontinence. In 2010, there were at least 100,000 pelvic organ prolapse repairs that used surgical mesh, and about 75,000 of these were transvaginal. These are the only procedures that the new FDA mesh warning applies to.
