I am in the process of donating a kidney. During testing they discovered my right kidney is 15% larger than my left. Therefore, to be absolutely sure they will be removing my right and opening me up versus laproscopic surgery, I am going on Monday to have a spilt renal function study done. Apparently, my anatomy is somewhat of an anomoly, being that I am a healthy 36 year old woman. Has anyone else encountered anything similar to my situation?
