(I've Googled this and got no answers) I just finished up kidney stones (my third time) and had a CT scan to ensure they were all gone, which they were. Reading the report, however, it states that there is "radiopaque material within the appendix". To me, this means something the x-ray cannot pass through, which concerns me. Even though I haven't passed a kidney stone in several days, I still have right flank and abdominal pain and occasional naseau. I have no blood in urine, but still a foul odor. Oh, I've had small hepatic cysts on my liver for years. I'm 46, fairly healthy, not overweight, not a drinker. I am a smoker My main concern here is the object in the appendix and ongoing discomfort, which I've talked myself into just being sore from the half-dozen stones I passed. Thanks for your help!
