I had brachytherapy done on Nov 29. 2007. I asked the doctor to put a catheter in because I was 100 miles from his office and didn't want to drive back for him to remove it. The nurse gave me the necessary equipment to remove it myself. I kept in a couple days and the removed it without any problem at all. Of course there is some irritation with using it but that went away in a few days. I hope this information helps.
