I went to Dr. Allon Kahn from Mayo in Phoenix. Outstanding Doctor and wonderful person. He removed my stent one day and trained me on the self dilation the next. Been doing on my own ever since. You will need to be fitted for the right size dilator. Mine is a 48FR. You can get the dilator from Dr. Kahn once it is determined what size you need. Good Luck and let me know if you decide to do this.
