What is water around the kidneys and dark marks behind them mean?

Answer 1

fuid collection around the kidneys may suggest infection or bleeding as well as trauma. "dark marks" means nothing per se, typically things like ultrasound, CT or MRI reading radiologists will describe an abnormal finding and say it suggests something like bleeding, abscess etc. If you could describe the exact words of the doctor, the context of what and why was being evaluated, then you could get a more detailed and explanatory response, good luck
