24 hrs post kidney transplant the graft not functioning. ultrasound showed a subcapsular hematoma, but no surgical removal was done. options?

Ask the doctor,...: What you reported-24 hrs-could be still normally expected although we like to see the transplanted kidney starts to make urine right away. So, I am quite sure it deserves a close watch and see. At times, a period of dialysis may be still needed, but the longer no urine with rising BUN and creatinine, the less to hope good outcome. For individual situation, please ask the transplanted surgeon.
