Hello. Thank you for posting.
In most cases, the transplanted kidney begins to make urine right away. Sometimes though, the kidney may have delayed function after surgery. This problem is called delayed graft function or acute tubular necrosis (ATN). We cannot know if this is the case for you, there might be another reason for this delay. How many days has it been?
Speak to your doctor who knows the specifics of your transplant and overall healrth.
