Nuclear kidney blood flow scan

VeryAnxious

Any one ever had one of these and what kind of results are we looking. After a robotic partial nephrectomy in October I just had it at 3 months and have read my report, but do not quite understand what I am looking at. See the doctor next week and also going for a second opinion. I know it is for how the kindey are functioning not to detect any cancer masses. Also had some blood tests. Is this the tyupe of tests they start at 3 months?
