The test told us a few things. First, the Ditropan is working well at the current dose. His bladder pressures stayed super low during the test. Second, it gave us an idea of how much his bladder can hold without leaking.
We will use that information in the coming week or two as we begin measuring how much urine output we get cathing Mason in the middle of the night and first thing in the morning. We're checking to see if we can forgo that midnight cathing. I have no idea if that will be a possibility. While the extra sleep would be nice (not having to wake up in the middle of the night every night to cath Mason) the important thing to us is protecting Mason's bladder and kidneys. So we'll do what we need to do.
It was a great appointment, Mason was cheerful and talkative through it all. He loved the elevator rides and is an old pro at the hour drive to the hospital and the hour drive home. We listened to music and to podcasts. The cutest thing was every time a truck passed us he would call out, "Come back truck! Come back to me."
