Abstract
Purpose:
To compare the dynamics of systemic inflammatory indices during laparoscopic nephrectomy (LN) and standard open donor nephrectomy.
Patients and Methods:
Participants in this cohort study were 54 adults without a history of renal surgery and no evidence of urinary tract infection who underwent transperitoneal LN (n=29) and open donor nephrectomy (n=25, control group). We recorded demographic characteristics, intraoperative parameters, and changes 24 hours postoperatively in systemic inflammatory and immunologic values (body temperature, concentrations of white blood cell count [WBC], C-reactive protein [CRP], interleukin [IL]-6, and tumor necrosis factor [TNF]-α), and compared the mean changes between groups.
Results:
Mean age was older in the LN group (45.6 vs 30.9 years; P<0.0001), and mean operative time was significantly shorter (83.1 min vs 101.6 min; P=0.004). Mean postoperative increase in IL-6 and body temperature in LN was significantly less than in control: For IL-6, 15.87 vs 29.09 pg/mL, P=0.03; for body temperature, +0.22°C vs +0.71°C, P=0.001). Mean postoperative increases in levels of other inflammatory markers (CRP, TNF-α, WBC) did not differ significantly. No statistical correlation was found between operative time and changes in IL-6, CRP, TNF-α, WBC, or body temperature.
Conclusion:
Based on the smaller increase in serum IL-6 as the most important indicator of surgical stress, the surgical trauma-induced immune dysfunction may be less intense after LN than open surgery. This may explain the smooth convalescence after LN.
