They didn't do a vein mapping, MRI or xray. 2 weeks before the surgery a kidney intern did a visual inspection of my left arm. When I asked him about vein mapping he said the dye woulddestroy kidney function. Made no sense to me . Minutes before the surgery, I asked the surgeon. He said these tests do not always give the correct results. I will ask my nephrologist whenI see him.Normally I would have demanded the mapping. But time is crucial. MY pd is mediocre and I am conserving energy to get by. The faster I switched to hemo, the better.I decided to have faith in the medical people.Update: saw the access nurse today. Everything is ok. Next Thursday she will take the bandage strips off.jg Happy April Fool's Day and then Happy Easter!
