Normal Ultrasound Assessment of the Renal Allograft

Clinical History

A 43-year old man with a recent history of  renal transplant surgery was referred to have an ultrasound assessment of the new renal allograft.

Case Description

The renal allograft appeared normal in size, outline, echotexture, and perfusion with no evidence of renal artery stenosis encountered.

Diagnosis/ Discussion/ Treatment/ Follow up

The ultrasound report was sent to the referring nephrologist.

During ultrasound assessment of the renal allografts, it is important to use a high frequency curvilinear transducer (6 – 7 MHz). This provides a reasonable balance between the acquisition of great image resolution, and having enough depth to visualise the graft and structures deep to and surrounding the graft.
