Normal Ultrasound Assessment of the Renal AllograftClinical HistoryA 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 DescriptionThe renal allograft appeared normal in size, outline, echotexture, and perfusion with no evidence of renal artery stenosis encountered.Diagnosis/ Discussion/ Treatment/ Follow upThe 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.SonogramsB-Mode sonogram of the normal transplant kidney in the left iliac fossa (LIF) Colour Doppler imaging of the normal transplant kidney showing excellent perfusion of the graftPower Doppler imaging of the normal transplant kidney showing excellent perfusion of the graftColour Doppler imaging of the transplant renal artery showing the point of anastomosis with the left external iliac arterySpectral Doppler imaging of the left external iliac artery measuring the peak systolic velocity (PSV) prior to the anastomosis Spectral Doppler imaging of the left external iliac artery measuring the peak systolic velocity (PSV) at the level of the anastomosisSpectral Doppler imaging of the transplant renal arterySpectral Doppler of the segmental artery within the transplant kidney Spectral Doppler of the intrarenal artery at the lower poleSpectral Doppler of the intrarenal artery at the interpolar region of the graftSpectral Doppler of the intrarenal artery at the upper polePublished on: September 25, 2024
