They use xrays, or what's much worse a CAT scan,
to verify the integrity of the jpouch, before they connect it to
your intestines. They can't shield your reproductive organs when
they do this. Your testicles or ovaries get zapped.
As a young person who might want to have kids some day,
If I were you, I'd try DIY fecal transplant first.
Search this website for the many threads on "fecal transplant"
If that doesn't work I'd demand that your gastroenterologist or family doctor prescribe you the triple antibiotic treatment described here:
If they won't, find a doctor who will. See this thread for more info:
I had my colon removed and a jpouch constructed April 4, 2011.
After 8 weeks with a ostomy bag (very unpleasant) I had the
jpouch connected June 2, 2011. I feel somewhat better
than before the surgery, but I'm still pooping 10-12 times per day
including 3-4 times at night, even with the opioid drug lomotil. (Immodium
was useless for me.)
Long before the surgery I did try DIY fecal transplants with my then 2-year old son's poop, but I couldn't hold them for long, and there was only minor improvement, so I gave up on it. I bitterly regret not trying fecal transplant with other donors, and that I didn't think of doing a Miralax-type prep to empty my digestive tract. I also bitterly regret not trying the triple antibiotic treatment.
It's hard to think clearly when your suffering from UC. Get somebody smart and savvy about medical issues to help you.
It's too bad the medical system in the USA sucks. You won't
be able to get colonoscopy-assisted fecal transplant here. Go
to Centre for Digestive Diseases in Australia if you can.
