No need for systemic heparinization during laparoscopic donor nephrectomy with short warm ischemia time

Area of Science:

• Nephrology
• Transplant Surgery
• Minimally Invasive Surgery

Background:

• Systemic heparin administration is sometimes used during laparoscopic donor nephrectomy (LDN) to prevent microvascular thrombus formation.
• The necessity and impact of heparinization in LDN, particularly with short warm ischemia times, require further investigation.

Purpose of the Study:

• To evaluate the impact of systemic heparinization on donor complications and graft outcomes during laparoscopic donor nephrectomy (LDN).
• To compare outcomes between LDN performed with and without systemic heparin administration.

Main Methods:

• Retrospective review of 119 live donor kidney transplantations.
• Comparison of donor complications and graft outcomes in 65 donors who received systemic heparin versus those who did not.
• All LDN procedures were performed using a pure laparoscopic technique.

Main Results:

• LDN operating time was significantly longer in the heparin group (202 vs. 157 minutes).
• The incidence of renal artery multiplicity was higher in the heparin group.
• Graft loss occurred in 3 donors in the heparin group and 1 in the non-heparin group, with no significant difference in 1-year graft survival (96.6%) or serum creatinine levels.

Conclusions:

• Abandoning systemic donor heparinization in LDN with short warm ischemia is associated with a low complication rate.
• The absence of heparinization did not adversely affect short- or long-term graft outcomes.
• This approach offers a safe alternative without compromising transplant success.
