Renal Pretransplantation Work-up, Donor, Recipient, Surgical Techniques

Area of Science:

• Nephrology
• Radiology
• Transplant Surgery

Background:

• End-stage renal disease (ESRD) necessitates renal transplantation as the optimal treatment.
• Accurate pre-transplant imaging is vital for successful donor and recipient evaluation.
• Understanding renal vascular and collecting system anatomy is critical for surgical outcomes.

Purpose of the Study:

• To highlight the utility of multiphase computed tomography (CT) in evaluating potential renal donors and recipients.
• To compare the advantages and limitations of CT and MR imaging in this context.
• To emphasize the importance of detailed vascular assessment for minimizing surgical risks.

Main Methods:

• Review of imaging techniques for renal transplant candidates.
• Focus on multiphase CT for comprehensive renal and vascular evaluation.
• Comparison with MR imaging, noting its limitations in stone detection.

Main Results:

• Multiphase CT offers detailed assessment of renal vascular anatomy and collecting systems.
• CT is preferred over MR imaging for donor evaluation due to superior stone detection.
• Preoperative imaging is essential for identifying vascular anomalies and incidental findings in both donors and recipients.

Conclusions:

• Multiphase CT is a highly effective imaging modality for pre-transplant donor and recipient assessment.
• Detailed vascular and anatomical knowledge from CT aids in risk mitigation for donors.
• Comprehensive imaging evaluation is crucial for recipient vascular assessment and identifying potential complications.
