Evaluating Predictive Factors for Lymphocele Formation Following Kidney Transplantation.

Introduction: Lymphocele is a common complication post-kidney transplantation, influenced by various factors including surgical technique, graft vessel count, operator experience, body mass index, ischemia time, and immunotherapy regimens. Project Aims: The purpose of this study was to evaluate lymphocele risk factors, particularly focusing on the role of end-stage kidney disease. Design: A retrospective study was conducted on renal transplant recipients from a single center (March 2020 to December 2022). Patients were categorized into those developing lymphocele and those without during the postoperative period. Data, including sociodemographic, personal history, graft-related variables, intervention, and postoperative outcomes, were collected from electronic medical records. Results: Out of 291 renal transplant recipients, 57 (19.6%) developed postoperative lymphocele, with 15 (5.1%) being symptomatic. Patients with body mass index <24.9 kg/m2 have lower risk of developing lymphocele with an Odds Ratio of 0.538 (P=0.046). Higher lymphocele prevalence was noted in patients with chronic tubulointerstitial nephritis (46.2%; OR 3.815; P=0.024). Focal segmental glomerulosclerosis patients showed no lymphocele (0.0%; OR 0.123; P=0.048). Other factors, including autosomal dominant polycystic kidney disease, did not exhibit significant differences in lymphocele prevalence. Conclusion: The etiology of end-stage kidney disease can serve as a significant predictor of lymphocele development during the postoperative period following renal transplantation. Further larger prospective studies are required to comprehensively assess risk factors and explore end-stage kidney disease potential role in predicting lymphocele formation. [ABSTRACT FROM AUTHOR]
