That way when you sneeze/cough/increase abdominal pressure you don't leak urine. Is this what you mean? If so, feel free to ask more as I have experience with it. Middle aged woman with one vag birth here. I can tell you some pros and cons, and no, MrUP can't feel any mesh, neither can I.
I had the sling, like on this website (good picture and explanation there.
http://www.mayoclinic.com/health/urinary-incontinence-surgery/WO00126Pros: don't leak when cough/sneeze/etc. Which is nice during cold seasons. I could probably jump on a trampoline again also.
Con: bladder is more sensitive, meaning I need to pee more often, have more urgency than before (if I gotta go, I gotta go). We hoped this was due to general surgical irritation, and would pass in time, but so far it hasn't (1 yr out). I am going to check into some physical therapy (ins won't pay for, but I will) soon for pelvic floor retraining.
I'd recommend anyone considering this to get P.T. first if possible, to learn how to control related muscles better. And get a second opinion from another doctor also.
I'm glad the stress incontinence is gone, but do not like the urgency issue. Pros and cons.
Probably more than anyone here wants to know about me, but oh well. Sharing info is good as there is lots of info (both ways) on the internets.
