Selection criteria for the evaluation of living related renal donors

The documented long-term health of the living related renal donor is a tribute to careful preoperative selection and surgical technique. At our medical center 187 prospective donors were evaluated during a 6-year period and 91 underwent donor nephrectomy. Hypertension, renal artery anomalies and donor indecision were the most common reasons for donor rejection. Recipient health and/or death, or a positive crossmatch after pre-transplant donor specific transfusion were other post-arteriogram reasons not to proceed with transplantation. Women were more likely to undergo nephrectomy than men, and older or heavier donors were more likely to be rejected. Using the transcostal, extrapleural surgical approach for nephrectomy there were no deaths or major complications, and the mean postoperative length of stay was 6.4 days. The average postoperative increase in serum creatinine was 0.33 mg./dl. with an average creatinine at discharge of the patient from the hospital of 1.2 mg./dl. The latter creatinine values varied concordantly with donor age. Only 56% of fully evaluated donors (91 of 159) actually underwent donor nephrectomy. The minimal morbidity sustained by these patients re-emphasizes the importance of careful donor selection.
