I did have the symptoms of a UTI after my colon resection but they only lasted the 7 days I was in the hospital and I tested negative for an actual infection. I was assigned a urologist while at Cedars Sinai and he kept track of me. Seems bladder issues are common and I think I was told this is because the bladder is so near the colon and pressure can be put on it during surgery. Maybe bruised? Just a thought.
