Abstract
Background: Many causes of renal transplant failure are potentially treatable; transplant recipients undergo routine surveillance so that complications are detected in the early and treatable stage. MRI is an excellent modality for renal imaging when compared with US or CT because of superior contrast resolution, multi-planar capability, lack of operator dependence and no need for intravenous iodinated CM. AIM OF WORK: This work aims to study the role of different MRI techniques in evaluation of early post kidney transplantation complications. Materials and Methods: This work was conducted on 128 renal transplant recipients. All patients were subjected to MRI study using different pulse sequences including T2wi as well as post-contrast sequences including MRA. Results: Overall distribution of post-transplant complications among the study groups according to MR findings as the following, among the studied 128 renal transplants, MR examinations detected 3 (2.3%) cases with graft arteries thrombosis, 5 (3.9%) with graft arteries stenosis, 5 (3.9%) with segmental infarctions and 2 (1.6%) cases with graft intrarenal arteries pseudo-aneurysms. MRI demonstrated urologic complications in 7 (5.5%) patients; 4 (3.1%) patients with urinary leakage, 1 (0.8%) patient with PUJO, 2 (1.6%) patients with ureteric obstruction. MRI detected 6 (4.7%) cases with perigraft haematomas, 5 (3.9%) cases with urinomas were detected, 6 (4.7%) cases with perigraft lymphoceles were diagnosed and 2 (1.6%) cases with abscesses formation. Conclusion: MRI is a valuable non invasive, non-nephrotoxic technique for the assessment of renal transplants in cases with suspicion of complications in transplanted kidney.
