No it wasn't done at Mayo but at the Thunder Bay Regional Health Sciences Center. I have a very bad history of blockages, strictures and stenosis in the urethra. They can form very rapidly, as little as two days after a foley catheter has been removed after either dilation or laser surgery. I did the self catheterization too, it helped for a little while but when I couldn't pass even a 12 mm catheter, they put in a foley. My Urologist wanted to have the supra pubic catheter in as a backup that would be used if I plugged up again, right now it is plugged off and will only be used if needed, it will be in for six months. He also said, he needs to be able to see exactly what's going on in my urethra without having a foley in place. He will be doing a scope later this month and replace the catheter. I finished radiation treatments back in late November, 33 treatments and didn't make it past a full week when I couldn't void at all. A surgeon at our local hospital couldn't get a foley in so they put a supra pubic catheter in, since then, right up to the Optilume treatment, I have had a catheter in. After my first laser surgery I went eleven months without any issues, the second laser surgery this past February only lasted a week before I started having voiding issues again. Really hoping the Optilume balloon works.
