Living donor nephrectomies-right side--intraoperative assessment of the right renal vascular pedicle in 112 cases.
Generally, the left kidney from a living donor is more commonly preferred but the right kidney is occasionally donated because of multiple left renal arteries or repeated transplantation. The right donor nephrectomy is usually more difficult compared to the left because the right renal vein is often multiple and short, which complicates dissection of the vascular pedicle. From Jan. 1989 to Sep. 1992, 112 consecutive cases of right donor nephrectomies out of a total of 771 cases were retrospectively reviewed with the preoperative renal angiography and the intraoperative assessment of the right renal vascular pedicle. The indications for right donor nephrectomy include 1) multiple or proximal bifurcating renal arteries of the left kidney (89.3%), 2) repeated transplantation in the recipient (9%). In 26.8% of the cases, there were more than two right renal veins. In the right donor nephrectomy, it is often necessary to perform vena cava cuff resection because of short and frequently occurring multiple right renal veins. For the dissection of the inferior vena cava (IVC), the aberrantly occurring right gonadal vein, the adrenal vein draining above the junction of the renal vein and IVC, and the lumbar vein below the junction should always be looked for and must be ligated if any are found.
