2005 prostate cancer radiation through those tissues weakened them. doctors don't know why the connection was made. all the doctors say to have the surgery as they have for the past 3 years for colon and bladder. yes, it would prevent kidney infections I am told since will keep the solids and liquids separate but am told that could still have infections through the stoma. I am not getting any younger for about an 8 hour surgery and long recovery so my kids say to do it but they are not around to take care of me. this has been ongoing and I am part of an ostomy support group so talk to them monthly about how they are doing and issues in have one or the other. hard to find someone that has both bags.
