Risk Factors Of Urosepsis After Percutaneous Nephrolithotomy

Objective: To investigate the risk factors of urosepsis so as to provide a theoretical basisfor the prevention of urosepsis after percutaneous nephrolithotomy.Methods: From September2011to September2013, the data of386patients treated byPCNL were analyzed retrospectively. Thirty-five patients were found with urosepsis.Single-factor and multi-factor analysis were tested for relevant factors.Results: Single-factor analysis revealed that female（P=0.000）, history of diabetes（P=0.003）, without preoperative treatment of antibiotics（P=0.036） and diameters ofstone＞2cm（P=0.041） are the main factors of urosepsis after PCNL. Furthermore,female and history of diabetes were considered to be the risk factors of urosepsis afterPCNL in multi-factor analysis.Conclusions: Female and history of diabetes are considered to be the independent riskfactors of urosepsis after PCNL. For the high-risk patients, preoperative treatment ofantibiotics can reduce urosepsis.
