Outcome of right hand-assisted retroperitoneoscopic living donor nephrectomy

To compare the results of right and left hand-assisted retroperitoneoscopic living donor nephrectomy (HARDN) and assess the usefulness and feasibility of right HARDN.

A total of 68 HARDNs performed from July 2001 to February 2005 in Akita University Medical Center were entered into this study. Of these, 12 cases were right-sided HARDN. The reasons for selecting right HARDN were wandering right kidney in 4, multiple left renal arteries in 3, lower glomerular function presenting in the right kidney in 2 patients, and left renal stone, right renal cyst, and right renal aneurysm in 1 patient each. We compared the perioperative and postoperative results of the 12 right-sided HARDNs with those of the 56 left HARDNs.

No significant differences were found between the two groups in the demographic data (ie, age, sex, number of renal arteries), except for the body mass index. None of the right HARDNs resulted in major complications or open conversion, but two left HARDNs required conversion to open surgery. No difference was found between the two groups regarding estimated blood loss, warm ischemia time, or time to oral intake, although the right HARDN group had a longer mean operative time. No significant differences were found in the recipient's postoperative graft function or in the frequency of delayed graft function.

Right HARDN provided almost similar perioperative and postoperative outcomes compared with those of left HARDN. Our results indicate that right HARDN is a choice for living donor nephrectomy because of its technical feasibility, safety, and minimal invasiveness, which are comparable to those of left HARDN.
