Abstract

Children who have undergone renal transplantation require regular imaging follow up and often have underlying medical conditions with multi-system involvement. These children benefit from multidisciplinary team input, a key component of which is Radiology. As the largest paediatric renal transplantation centre in the UK, the imaging department at Great Ormond Street Hospital are experienced at providing high quality imaging studies and technically complex interpretations in the immediate and long term follow up of renal transplantation patients. On average 26 transplant surgeries are performed each year with the figures exponentially increasing, leading to the demand for ultrasound rising with on average 62 studies per month.

We present an educational review of imaging post renal transplantation. As the primary imaging modality used in these scenarios, we will focus on ultrasound and normal sonographic appearances of a renal graft after transplantation. We will review the benefits, technique and limitations of using ultrasound. We will also touch upon other imaging modalities that can be used in more complex cases. Our selection of cases with complications include perinephric collection, urine leak, thrombosis and a special complex case of autologous transplant rejection secondary to renal artery involvement in neurofibromatosis.

Following this educational presentation, attendees should be able to:

  1. Correctly identify the normal anatomy of a kidney and relate this to structures seen on ultrasound

  2. Describe normal and abnormal Doppler waveforms in a transplanted kidney

  3. Identify early and late complications and their imaging correlates, including the limitation of ultrasound being unable to identify acute rejection/ATN.
