Laparoscopic techniques are increasingly being used for live donor nephrectomy for kidney transplantation. The technical methods have been rapidly adopted by the transplant community, but remain limited by the requirement for pneumoperitoneum, a technique that increases intra-abdominal pressure to gain surgical exposure. Pneumoperitoneum reduces renal cortical blood flow, potentially inducing ischemia associated factors that promote allograft rejection or attenuate post transplant renal function.
The aim of this study is to determine the effects of pneumoperitoneum used for minimally invasive donor nephrectomy on renal perfusion using infrared imaging. Our goals are to:
1. Analyze the effect of varying levels of pneumoperitoneum intraoperatively using infrared imaging;
2. Correlate the effects of both open and laparoscopic living donation with respect to transcriptional events, donor and recipient renal function, urine output, post-operative pain and return to work postoperatively;
3. Determine optimal conditions for procurement of renal allografts for subjects undergoing renal transplantation.
In this study, patients will be those who have been consented to kidney donation on the Live Donor Renal Donation for Allotransplantation (99-DK-0107). This study will represent the first such use of infrared imaging and the first prospective evaluation of strategies for living kidney donation.
