I had to have several dilations and chose to have the "in office" procedure with the sounds rather than the surgical procedure. I avoid hospitals and anesthesia when possible. The actual dilation only took a few minutes and was very uncomfortable at the time the actual stretching took place. No catheter was necessary. I had to repeat the procedure several times but have not had any problems over the last few years. Pop a couple of extra strength Tylenols before you go in.
