More Henry troubles

Took Henry in on Friday to get his stitches removed from his SECOND PU surgery (first one closed up too farand he couldn't pee). He has scar tissure again, and the vet did ANOTHER surgery, but this time he came home with a 2 inch catheter sewn into his urethra and he has an appointment with a specialist about 45 minutes away next Friday. Has anyone gone through this? I was hoping the surgery would correct the problem, but if it won't heal properly, we'll never know if it actually works.
