Hemostatic Agent May Improve Perioperative Outcomes in Partial Nephrectomy: A Systematic Review and Meta-Analysis

Hemostatic agents (HAs) are used to achieve hemostasis and prevent postoperative complications in multiple surgeries, but the role of HAs is ambiguous during partial nephrectomy (PN), so this study aimed to assess the role of HAs in PN.

PubMed, Embase, CENTRAL and ClinicalTrials.gov were searched for randomized controlled trials and cohort studies regarding the comparison of HA use alone and standard suturing during PN on January 17, 2020. RevMan 5.3 was used to conduct meta-analysis. Sensitivity analyses and subgroup analyses were performed based on surgical procedures and HA types.

Six studies involving 1,066 patients were included. The quality of studies was moderate to high. There were significant reductions in warm ischemia time (mean difference [MD] = -6.30 min, 95% confidence interval [CI] -7.70 to -4.90, p < 0.00001), operative time (MD = -19.81 min, 95% CI -27.54 to -12.08, p < 0.00001), and estimated blood loss (MD = -108.62 mL, 95% CI -177.27 to -39.9, p = 0.002) in the HA group, and HA use alone did not increase postoperative complications. The results were similar in the subgroup analyses and sensitivity analyses.

HA may be an effective and safe surgical material in PN, which can improve postoperative outcomes. High-quality and randomly designed studies are needed to validate the applicability.
