During the robotic prostatectomy surgery, do they put the foley catheter in before or during the surgery?

Here are some ....: Insert one before the procedure to assist visualizing and "feeling" the urethra for transecting the urethra during the procedure. After that, the first one is removed and replaced with another one to assist connecting urethra to bladder neck and for postoperative care, just like open prostatectomy. At times, the same one can be used as long as it is not cut or damaged. For detail, ask Doc.
