Effect of prolonged warm ischemia and pneumoperitoneum on renal function in a rat syngeneic kidney transplantation model
Surgical Endoscopy: surgical and interventional techniques , Volume 20 - Issue 7 p. 1113- 1118
Background: Laparoscopic donor nephrectomy is associated with several advantages for the donor. However, graft function may be impaired due to use of pneumoperitoneum and prolonged warm ischemia. This study investigated the impact of pneumoperitoneum and prolonged warm ischemia on long-term graft function in a syngeneic rat renal transplant model. Methods: A total of 27 Brown Norway rats were randomized for transplantation of kidneys after three different procedures: no insufflation and no warm ischemia (group 1), no insufflation with 20 min of warm ischemia (group 2), and CO2 insufflation and 20 min of warm ischemia (group 3). Glomerular filtration rate (GRF), serum creatinine, urine volume, urine creatinine, and proteinuria were determined monthly for 1 year. One year after transplantation, the grafts were removed for histomorphologic analysis. Results: No significant differences in GRF, serum creatinine, urine volume, and proteinuria were found among the three groups. Histologic analysis also showed no differences between the groups. Conclusions: Warm ischemia in combination with CO2 pneumoperitoneum, as used in laparoscopic donor nephrectomy, does not result in a negative effect on long-term graft function.
