Good!! Please keep us informed about your follow up visit and decisions that are made. Good Luck .
Saw urologist yesterday. Said there wasnt an urgency in regard to the 21 mm because it isnt causing a blockage presently. Myself, Im concerned with the rate its growing. In regard to the cyst the urologist will look at the CT images for signs that it is something other than just fluid. Said we may do other imaging with contrast to confirm it isnt something bad. I go back in two weeks.
If it was my cat scan and I saw those results, the first thing I'd do is get an appointment with my/an Urologist ASAP! I'd have a serious discussion with him/her regarding the cist and this large stone and the medical/health benefits or pitfalls for removal of both. That's a very large stone and you should also descuss the seriousness of that cist, it's size and potential problems for you and then go from there with both things after that informed discussion with the Urologist. I wouldn't want to say what you should do, one way or the other, and only a Urologist can help you make an informed decision.
