a scan for kidney stones ( which showed that I didn't have any big enough to worry about ), showed a swelling on one kidney....I am seeing the consultant in 10 weeks...... I would like to know more before the visit....my knowledge of anatomy and biology is rather sketchy.....any input will be read with interest.
If the scan has shown a swelling on one kidney, then knowledge of anatomy is not necessary.......it is on the kidney.
By far the commonest "swellings" on the kidney are benign (innocent) cysts, which do not require any treatment.
There are other causes, but far less common.
