A Technical Improvement of Right Renal Vein Elongation in Orthotopic Renal Autotransplantation

We propose a technique improvement to solve the anatomic problems of the right renal vein during renal autotransplantation to facilitate the performance of the right kidney. The technique improvement involves extension of the right renal vein with an inferior vena cava patch. The technique was performed successfully in three cases of renal artery stenosis, without technical or surgical complications. Our improvement technique solves the anatomic problems of the right renal vein, and decreases the difficulty of operation and risk of complications.
