Abstract
Background
The aims of this study were to provide an overview of techniques for renal artery reconstruction and to introduce a novel technique using the gonadal vein as a “Carrel patch.”
Materials and Methods
From January 2005 to December 2011, we performed 128 live donor kidney transplantations. All donor nephrectomies used laparoscopic surgery, yielding 23 grafts with 2 and 3 with 3 renal arteries. The reconstruction technique was based on the length and caliber of the arteries. For 3 renal arteries, we used the gonadal vein as a “Carrel patch”. The gonadal vein was harvested with the ureter as a bundle during nephrectomy. The recipients were 1.5 to 71 years old (average, 43.9).
Results
All laparoscopic donor nephrectomies were performed successfully with preservation of the multiple arteries. The reconstructions were satisfactory; all grafts functioned immediately. There was no arterial infarction on postoperative Doppler ultrasound and renal nuclear scan. Renal artery stenosis occurred in 2 cases, in which the interventional balloon dilatation was first used; 1 case required subsequent stent insertion.
Conclusion
In cases of multiple renal arteries, the live donor kidney can be recovered safely by laparoscopic surgery. Our technique to reconstruct multiple renal arteries uses the gonadal vein as a “Carrel patch.” The gonadal vein is readily available during laparoscopic donor nephrectomy.
