I just recently had kidney stone laser surgery and I am on pain pills every 4 hours. I just woke up and urinated dark blood and my right kidney is very painful. I have been drinking lots of water and usually the pain goes away in about 20 minutes. The last time I had a stool of any significance was about 5 days ago. What should I be doing?
Hi, First thing for you to do is consult your urologist. You have not mentioned how recently your surgery was done. If it is less than a week possibly it is post-operative pain. The fact that you're passing dark urine suggest there is bleeding from urinary tract. The clots must be blocking your ureters and causing pain. Check if you are having fever. Get complete blood count done. Consult your urologist immediately.  Also, you are constipated. If you are not eating properly then that could be the cause.
