Kidney Transplant
Focused evaluation for long-term transplant health
A transplant kidney biopsy, also called a graft biopsy, is performed on the transplanted kidney (allograft) to assess its health, identify causes of graft dysfunction, and guide post-transplant treatment. Since a transplanted kidney behaves differently from native kidneys, this biopsy provides specialised information essential for long-term graft survival.
Why is a Transplant (Graft) Biopsy Done?
1. When there is graft dysfunction (Indication Biopsy)
A biopsy may be recommended if you have:
- Rising creatinine
- Reduced urine output
- Sudden swelling or discomfort over the graft
- Proteinuria or blood in urine
- Suspected acute or chronic rejection
- Possible drug toxicity, especially from tacrolimus or cyclosporine
- Suspected viral infections like BK virus nephropathy
2. As part of routine post-transplant monitoring (Protocol Biopsy)
Many transplant programs perform scheduled biopsies even when kidney tests appear normal to detect:
- Silent rejection
- Early chronic changes
- Subclinical inflammation
These biopsies help preserve long-term graft function.
What Makes a Transplant Biopsy Different?
- The transplanted kidney is located superficially in the lower abdomen, making biopsy access easier.
- The biopsy gives specific information about immune-mediated injury, drug effects, recurrent diseases, and chronic graft changes.
- It allows early intervention to prevent permanent graft damage.
What Does a Transplant Biopsy Diagnose?
Key conditions identified include:
- Acute cellular rejection
- Antibody-mediated rejection (AMR)
- Chronic allograft injury
- Drug toxicity from immunosuppressants
- BK virus nephropathy
- Recurrent or new kidney diseases in the graft
These findings play a central role in deciding immunosuppression levels and treatment strategies.
After the Biopsy
(General biopsy monitoring details are already explained in the native kidney biopsy section.)
For transplant biopsy specifically:
- Patients are observed closely because even minor changes can affect graft health.
- Activity restrictions and follow-up plans are emphasised to safeguard the transplant.
