Background: Lymphoceles are amongst the most common complications following kidney transplantation. Therefore, effective strategies to prevent their development are needed. The ligation of lymphatic vessels has proven to be a successful concept for that purpose. However, whether electrocauterization or suture ligation is more effective is unclear. Methods: We conducted a meta-analysis using a random effects model with the log risk ratio as the primary outcome measure. Additionally, an analysis using a random effects model with the raw mean difference in lymphatic sealing time between suture ligation and electrocauterization was performed. Adequate studies were found in a literature search conducted in PubMed, CENTRAL and Web of Science as well as from independent sources. Results: A total of 8 studies including 601 patients were included in the analysis. The estimated average log risk ratio based on the random effects model was µ = −0.374 (95% CI: −0.949 to 0.201), which did not differ significantly from zero (z = −1.28, p = 0.2). The lymphatic sealing time was 7.28 (95% CI:1.25–13.3) minutes shorter in the electrocauterization group. Conclusions: We conclude that neither technique is superior for the purpose of lymphocele prevention post kidney transplantation, and secondary criteria like time savings, cost and surgeons’ preference should be considered in the decision for an optimal outcome.
