I had the urodynamics procedure and it was more of a discomfort than painful. The PA and nurse who performed it were so nice and made me comfortable. I did not have it done lying down but rather on a special chair with a cutout so if you gush, which at a point I did, it goes on the floor onto towels. It's sterile water that they keep putting in to see if it comes out when you cough. Although fake coughing is nothing like real coughing. But I eventually failed the test and the water came flooding out. So now the surgeon is wanting to put in a mesh mid urethral sling at the same time as my hysterectomy and colpocleisis surgery. I'm not sure if I want to have mesh put in due to it's ability to corrode. Hoping some women will post if they have had to make the decision to have the mid urethral sling and how long has it lasted.
