Multiphasic MDCT of Living Renal Donors, Prior to Surgery

Abstract

Background: Live kidney donor evaluation mandates anatomical and functional assessment of the donor kidney. Multiphasic Multidetector computed tomography (MDCT) with advanced 3‐D techniques provides a detailed description of the vascular, parenchymal, and collecting system.
Objectives: To evaluate the clinical application of Multiphasic MDCT in the pre-operative anatomic assessment of prospective donor kidneys.
Methods: Multiphasic MDCT was performed in thirty-eight patients as part of a pre-operative assessment. Each study comprised three phases of imaging, including the arterial, venous, and excretory phases.
Results: The predominant radiological finding amongst the cases studied was that of the presence of accessory renal arteries in 35% of the patients. Multiphasic MDT was also able to detect renal parenchymal disease in one case. Post-renal anatomical evaluation also identified renal calculi in 12.5% of the total cases.
Conclusions: There is considerable scope for multiphasic MDCT in the pre-operative evaluation of donor kidneys, especially as modern-day renal transplant surgery sees a shift towards laparoscopic techniques where intraoperative anatomic evaluation can be restricted. The multiphasic MDCT is useful in pre-renal, renal, and post-renal anatomic evaluation. Advances in Knowledge: Multiphasic MDCT can provide noninvasive, detailed, and fast images to aid the preoperative evaluation of donor kidneys.
