My stepfather has been bleeding during urination several months. he's had an illiostomi and triple bypass. is this new surgery safe for him? age: 73

Evaluation: His heart is optimized, which is a good. His surgeon and his consulting physicians will deside what needs to be done to make surgery safe.

Yes: Since your stepfather has had an ileostomy and triple bypass, i will assume the surgery is for blood in his urine. His heart is now safe from having a heart attack because of the bypasses. Usually non-cardiac surgery is done a couple of weeks after the bypass surgery.
