Preoperative inflammatory biomarkers analysis in prognosis of systemic inflammatory response syndrome following percutaneous nephrolithotomy: A systematic review and meta-analysis.

Introduction: Urosepsis is one of the most serious complications of percutaneous nephrolithotomy (PCNL). To date, many studies aim to prescreen urosepsis possibility after PCNL through blood components. This meta-analysis aims to determine C-reactive protein (CRP), neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) obtained preoperatively used to predict postoperative sepsis after PCNL.
