My husband had an 8cm kidney stone in 2010...he had 3 surgical procedures to remove it & 3 stents...just went to doctor because of chest & back pain & they seen a on his cat scan that his kidney was huge & strangely shaped & blocked & looked strange so they sent us for a nuclear scan today & determined his kidney has no function & no blood flow but wouldn't tell us anything else ...im on pins & needles waiting to find out what to do next...does anyone have any thoughts as to why this would happen and how we might proceed?
