Suspecting kidney removal. Out things.

Hello there! One of my friend was suffering from cold abscess for which surgery was performed about an year ago on the right back side just near to kidney... recently we got to know that she has only one kidney on the left.. on scanning we got to kno that left kidney is slightly larger than its normal size which means she could be having one kidney right from birth but we never got to know... We are trying to understand whether it is possible to remove kidney during this surgery ... for better idea of the exact location am attachig the pic where operation was performed... Also attaching the discharge summary of the patient. After the surgery the doctor had told her after few years u will start getting eye problems and now she is suffering from cataract. We are trying to simulate all this and clear out things... Thanks for your reply in advance.
