¿Existe asociación del tiempo entre el urocultivo y la cirugía intrarrenal retrógrada y la tasa de síndrome de respuesta inflamatoria sistémica?

Abstract

ObjectiveTo identify the preoperative and intraoperative factors that might cause systemic inflammatory response syndrome (SIRS) after retrograde intrarenal surgery (RIRS), and to investigate the effect of time elapsed between the date of performing preoperative bladder urine culture (PBUC) and surgery date on postoperative SIRS. Materials and methodsFour hundred sixty-seven patients who had RIRS between January 2013 and June 2020 constituted the target population of this study. PBUC were obtained from all patients before undergoing surgery. Postoperatively, patients were closely monitored for fever and other signs of SIRS. Univariate and multivariate logistic regression analysis were performed to reveal the predictive factors for SIRS after RIRS. ResultsThe entire study cohort consisted of 467 patients. The rate of SIRS was 5.6%. In univariate analysis, the rate of diabetes mellitus, recurrent urinary tract infection history, surgical time, and stone burden were significant predictive factors for SIRS. In multivariate analysis, the rate of recurrent urinary tract infection history, surgical time and stone burden were observed to be statistically significant predictive factors. Time elapsed between the date of performing PBUC and surgery date was not different between the SIRS group and the normal group. ConclusionWe conclude that the time between the date of performing PBUC and surgery date is not an influential factor for SIRS. Clarifying this issue with prospective studies may be useful, as endourologists frequently encounter this situation in daily practice.
