I just noticed this thread had resurfaced. In case anyone is curious...

Michael was about to leave on a week-long mountain hike when he had the problems I described in the original post.

• He was going to cancel - any recurrence while in the wilderness could be fatal.
• Then he realized learning how to catheterize himself was a much better choice. (Once he had overcome his squeamishness.)
• He did the hike and had no problems. Hooray!
• About 3 months ago, he had surgery to clean out (?) the prostate gland. I don't fully understand it, but I think the surgeon cut into the prostate and sewed it up afterward, so he still has a prostate gland. (When I had mine removed using robotic surgery, I don't remember hearing about this as an option).

In 90 minutes I will be going for a ride with Michael. He really liked the 2 rides I described in the original post, and now he's decided to start riding again. Last week we rode a flat 15 and then 18 that added a big hill. Hooray!
