I took him to the E.R., they did xrays, and ultrasound, and blood work. No stones were seen on x ray, nothing on ultrasound, and nothing in the blood work. They did put a catheter in because they were thinking that maybe the stone was just out of view, she felt nothing with the catheter. His bladder was extremely large and his body temp was 95. They injected him subcutaneously with some water injections to help hydrate him and allowed me to take him home. I immediately took Saint to his regular physician this morning and they have hospitalized him for the next few days. His urine was dark red, full of blood, when they ran the catheter. She said his bladder had already swollen back up over night. I am so worried that something more may be going on. He is like my son and I want to do whatever I can for him.
