Introduction: Left laparoscopic donor nephrectomy (LDN) is preferred over right LDN due to technical ease. The purpose of this study was to compare results between right and left LDN and thereby determine whether substantial experience with right LDN can provide results equivalent to left LDN.
Methods: All LDN from 2000 to 2004 were reviewed, and right LDN data compared to left LDN data. Statistical analyses included chi-square and Student t tests.
Results: Two hundred thirteen left LDN (84%) were compared to 40 right LDN (16%). Donor age, gender, race, and body mass index, and multiple arteries were similar in right and left LDN groups. Operative and cold ischemia times were similar, but warm ischemia was longer for right LDN (3:55 +/- 1:22 minutes) than left LDN (3.18 +/- 1:06 minutes; P = .004). Despite this, renal allograft function was similar on postoperative day 7 (creatinine 1.77 +/- 1.21 for right LDN, 1.7 +/- 1.5 for left LDN) and at 1 year (right LDN 1.5 +/- 0.4, left LDN 1.23 +/- 0.28). Graft survival rate in the right LDN at 1 year was 97.5%.
Conclusions: This large experience with right LDN indicates that results comparable to left LDN can be obtained. This observation increases the options for LDN in patients with multiple left renal arteries, or with right renal cysts, or with right kidneys that are smaller in size compared to the contralateral left kidney.
