Comparison of changes in tissue oxidative-stress markers in experimental model of open, laparoscopic, and retroperitoneoscopic donor nephrectomy.
OBJECTIVE
We evaluated the oxidative stress in renal tissue during three types of surgery: open donor nephrectomy (ODN), laparoscopic donor nephrectomy (LDN), and retroperitoneoscopic donor nephrectomy (RDN). The aim was to find out which is the appropriate procedure for harvesting a donor kidney.


METHODS
Twenty-four New Zealand White rabbits were randomized to four groups, each consisting of six rabbits. Group I (control) was subjected to 180 minutes of anesthesia, and transperitoneal nephrectomy was performed without creation of warm ischemia. In group II (ODN), after 180 minutes of anesthesia, warm ischemia was created for 5 minutes, and nephrectomy was performed. Group III (LDN) was subjected to 5 minutes of warm ischemia after 180 minutes of pneumoperitoneum at 12 mm Hg, and the kidney was removed. In group IV (RDN), after pneumoretroperitoneum at 12 mm Hg for 180 minutes, warm ischemia was created for 5 minutes, and nephrectomy was performed. Renal tissues were analyzed to determine malondialdehyde (MDA) and reduced glutathione (GSH) as oxidative-stress markers.


RESULTS
Renal tissue GSH levels were decreased, whereas MDA levels were increased in groups II through IV compared with the control group (p<0.05). There was no statistically significant difference between the ODN, LDN, and RDN groups in the renal oxidative-stress markers.


CONCLUSIONS
No differences were detected in oxidative-stress markers in renal tissue samples between ODN, LDN, and RDN. Therefore, we believe LDN and RDN can be used for live donor kidney harvesting as effectively as ODN without creating greater oxidative stress, which can have deleterious effects on a donor kidney.
