Last night the nurse tried to explain what went on during stenting of the right kidney. She got it wrong. The urologist came in and explained. They went to stent the kidney so the stone would not cause a problem. When they put it in dark, murky stuff started to come out. This could be old blood from the first liver transplant or it could be an infection. They decided to check the left side and found the same. They stented that one as well and sent the samples to the lab. The stone is still there. They do not want to mess with that until he is better. They will remove or replace the stent in a month.
