Purpose:
Laparoscopic donor nephrectomy is an established procedure in the porcine model. We sought to compare intraoperative variables between live laparoscopic (LAP) and laparoscopy-assisted (LAP-A) donor nephrectomy.
Materials And Methods:
Eight domestic pigs underwent either traditional laparoscopic donor nephrectomy (N = 4) or laparoscopy-assisted donor nephrectomy (N = 4) using the Pneumosleeve followed by conventional heterotopic autotransplantation.
Results:
No significant differences were noted between the groups with regard to vessel length, ureteral length, or postoperative urine output. The operating room time was 108+/-12 minutes in the LAP group v 75.8+/-10.3 minutes in the LAP-A group (P = 0.0065). Although the difference was not statistically significant, warm ischemic time, tended to be lower in the LAP-A than the LAP group: 70+/-3.0 seconds v 135+/-57 seconds, respectively (P = 0.059). Graft survival was identical in the two groups.
Conclusion:
Laparoscopy-assisted (via Pneumosleeve) live donor nephrectomy shortens the operative time without affecting graft survival in the domestic swine model.
