Renal transplantation is one, if not the most, common transplant procedures undertaken worldwide. Consequently, purposeful and incidental imaging of renal transplants and renal transplant-related complications are increasingly common. These include acute renal transplant rejection and chronic renal transplant rejection. Both renal donors and recipients undergo a pre-operative workup.
Most renal transplants are sited in the extraperitoneal right iliac fossa. For a variety of surgical reasons (including vessel suitability or previous failed renal transplants), they may occur in the left iliac fossa or elsewhere.
- renal transplant not often visualised directly as obscured by other soft tissues of the pelvis but may be visible if calcified (i.e. failed)
- surgical paraphernalia such as clips and ureteric stents may be visible
- complications related to underlying disease, or the renal transplant and its associated anti-rejection medications (e.g. osteonecrosis)
Renal transplant ultrasound is commonly utilised to evaluate for complications post-operatively. Read the separate article on this for US features.
