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.
