Right renal vein is smaller in length and its wall is very thin, especially at its junction with inferior vena cava (IVC). If right renal vein is divided at its junction with vena cava, anastomosis in recipient is not easy due to its short length as well as tearing of the thin part of the vein. To avoid tear if the thin part of the vein is removed it causes further shortening of its length, thus making anastomosis more difficult. If a cuff of vena cava is taken along with right renal vein it increases the length of the renal vein as well as provides a thick and sturdy wall of IVC for anastomosis and thus reducing the problems.
We used this technique in 132 patients who underwent live related renal transplant between January 1990 to April 1999. The main indication for right donor nephrectomy was multiple renal arteries on left side (90.4%), while a single renal artery on right side.
Methods & Results
All donor nephrectomies were performed by extraperitoneal flank approach with subperiosteal excision of the 12th rib. IVC was mobilized after ligating the gonadal and lumbar vein if encountered during the dissection. The junction of right renal vein and vena cava was mobilized completely. Renal artery was dissected from behind and divided after applying a clamp. A Satinsky clamp was applied on the vena cava to occlude it partially and a 3-5mm cuff of vena cava was excised along with right renal vein. The inferior vena cava was repaired with 4/0 prolene. Cuff of the IVC was anastomosed with external iliac vein end to side using 5/0 prolene. However, one should not pull the kidney while performing anastomosis as it may cause tear at the junction of IVC cuff and renal vein which is very thin.
We have performed 132 right donor nephrectomies without any significant complications. However, 12.2% patients had post operative minor complications like wound infections (6%), UTI (3%), collection in renal fossa (1.2%) and pleural injury in 2.0%.
Comparison with Other Methods
The left kidney is usually preferred in live related renal transplant because it has a longer vein which facilitates anastomosis in recipients.  Few millimeters of vena cava cuff with the right renal vein increases its length and helps in anastomosis with recipient vein as it becomes easy and safe.  This practice is commonly performed in cadaveric renal transplants, whereas it is not popular in living related renal transplant due to the potential risk of IVC cuff excision and the possibility of bleeding. There was no short or long term problem associated with partially clamping the IVC as well as the repair of IVC defect. It is easier to repair the defect than to anastomose a small renal vein stump.
IVC cuff increases the length of the right renal vein as well as it provides a relatively tough tissue for anastomosis. This extra length makes the anastomosis easy, quick and safe.[Figure 1],[Figure 2],[Figure 3]
