What is the optimal approach for the end-stage diabetic nephropathy patient considering simultaneous pancreas-kidney transplantation?

This case-based discussion regards two very different patients with end-stage diabetic nephropathy (ESDN) who are considering transplantation. What is the best approach for each individual: pancreas-kidney transplant or kidney transplant alone? Suppose a live kidney donor is available? What are the risks and benefits of each approach? In the candidate evaluation process, medical issues, such as uncorrectable coronary artery disease, are investigated and may preclude transplantation altogether or dictate the optimal approach. Similarly, a careful psychosocial profile is important to tailor the approach to the patient. The multidisciplinary transplant team has an obligation to provide informed consent, foster realistic expectations, and advise the candidate based on collective expertise. Ultimately, the decision as to the best course-pancreas-kidney, kidney transplant alone, or no transplantation-is the result of a collaborative effort between the patient and the transplant team.

Assessment of living renal donors with spiral CT.

PURPOSE: To determine whether spiral computed tomography (CT) can be used to evaluate potential living renal donors. MATERIALS AND METHODS: Twelve potential living renal donors underwent spiral CT and conventional arteriography. CT angiography was performed with 30-second spiral acquisition during injection of 150 mL of nonionic iodinated contrast material into an antecubital vein at 5 mL/sec. Five minutes after injection, a frontal abdominal scout projection was obtained to assess the renal collecting system. Results of blinded interpretations of axial CT angiograms, three-dimensional CT angiograms, and conventional arteriograms were correlated with intraoperative findings in 11 cases. RESULTS: Axial and three-dimensional CT angiography were 100% sensitive for identifying seven accessory renal arteries and 14% and 93% sensitive for identifying five prehilar renal artery branches. Renal venous anomalies were confirmed in three patients at surgery. Operative management changed in four of 11 patients who underwent donor nephrectomy. CONCLUSION: Spiral CT holds promise as a single examination for anatomic assessment of living renal donors.
