Well, the results are in. The lesion hasn't changed, so my urologist says I can wait for a year and follow up with an ultrasound. So that's good. The not so good news is that the scan showed a sacral stress fracture. I guess that explains some pretty intense pain I'd been having a few weeks ago in my right glute. Turns out it was a fracture. So, to be sure, my urologist wants to rule out anything sinister in the cause of the fracture. He gave me a prostrate exam (without dinner and drinks beforehand, no less). Then I got a blood test and when I get back from a trip in a few weeks, I get a bone scan.
So, kidney ok, scrap fracture not so good. LOL. It's always something.
