What is Delayed Graft Function (DGF)?

Delayed Graft Function (DGF) is a condition where a newly transplanted kidney does not start working straight away. Patients with DGF may need dialysis within the first weeks after surgery while the kidney recovers.

Is DGF common?

Yes, DGF occurs in around 1 in 3 kidney transplants. It is more common when the donor kidney comes from a deceased donor, especially when donated after circulatory death (DCD).

Why does DGF happen?

Several factors can contribute to DGF, including how long the kidney was outside the body before transplantation, the age and health of the donor, the type of donor (living or deceased), and the immune or medical status of the recipient.

How is DGF diagnosed?

DGF is commonly diagnosed if dialysis is required within the first 7 days after transplant. Doctors may also monitor creatinine levels, urine output, and other signs that the kidney is taking time to ‘wake up’ following transplant.

Does DGF mean the transplant has failed?

No. Many kidneys affected by DGF go on to work well in the long term. DGF means a delay, not failure. However, it may be linked with longer hospital stays and a higher risk of complications.

How is DGF treated?

DGF is managed with supportive care. This may include dialysis, medications to control blood pressure and fluid levels, and close monitoring of kidney function. Often, kidneys begin to work gradually over days to weeks.

Can DGF be prevented?

Some strategies during surgery and organ preservation can reduce the risk, but not all causes of DGF are preventable. Your nephrology and transplant team works carefully to minimise the risk wherever possible.

What does this mean for me as a patient?

If you experience DGF, you may need a few sessions of dialysis and a longer hospital stay. It may feel discouraging, but your care team will closely monitor your recovery. Most importantly, DGF does not mean your transplant has failed.
