Body mass index influence on short-term perioperative results in robotic-assisted laparoscopic partial nephrectomy: a comprehensive systematic review and meta-analysis

The objective of this meta-analysis was to evaluate the perioperative outcomes of robotic-assisted partial nephrectomy (RAPN) in obese and non-obese patients. Through March 2024, we executed an exhaustive search in internationally acclaimed databases such as PubMed, Cochrane Library, and Web of Science, limiting our scope to publications in English. We discarded review articles, protocols lacking empirical data, conference abstracts, and materials not pertinent to our research. Our analytical framework utilized the Cochran –Mantel–Haenszel method alongside a random-effects model for evaluating dichotomous variables’ mean differences, expressed through odds ratios (OR) with 95% confidence intervals (CI). We established statistical significance at aP value below 0.05. The comprehensive meta-analysis incorporated data from eight cohort studies, collectively assessing 3657 patients. Findings indicated that, relative to individuals of normal weight, those in the obese category had prolonged operative durations (WMD − 25.68 95% CI − 42.07 to − 9.29;P = 0.002), increased estimated blood loss (WMD − 48.55ml, 95% CI − 78.27 to − 18.83;P = 0.001), and longer warm ischemia times (WMD − 1.11, 95% CI − 2.03 to − 0.19;P = 0.02). However, no significant disparities were observed in hospital stay duration, intraoperative and total postoperative complications, severe postoperative complications, or alterations in postoperative estimated glomerular ...
