title: [Mortality predictive factors in patients with urinary sepsis associated to upper urinary tract calculi].
abstract: OBJECTIVE
  The aims of this study were to determine the clinical characteristics of patients with urinary sepsis associated to ureteral calculi admitted to the Intensive Care Unit (ICU), and to identify predictors of mortality in the first 24 hours of admission.
  
  
  METHODS
  A retrospective observational study covering a 16-year period (2006-2011) was carried out.
  
  
  METHODS
  The combined clinical/surgical ICU of a secondary-level University hospital.
  
  
  METHODS
  All patients admitted to the ICU due to obstructive urinary sepsis.
  
  
  METHODS
  None.
  
  
  METHODS
  We analyzed general clinical and laboratory test and urological data. The diagnostic technique, affected side, decompression technique, isolated microorganism and antibiotic therapy used were also considered. The assessment of risk factors was performed by multiple logistic regression analysis.
  
  
  RESULTS
  A total of 107 patients admitted to the ICU were included in the study, with a mortality rate of 19.6%. The diagnosis was mainly established by ultrasound, and the most commonly used decompression technique was retrograde JJ stenting. Microorganisms were isolated in 48.6% of the patients. In total, 20.6% of the patients had bacteremia. Multivariate analysis found age, acute renal failure and the use of vasoactive drugs administered continuously for the first 24 hours of admission to be independently associated to mortality.
  
  
  CONCLUSIONS
  Advanced age, acute renal failure and the need for vasoactive drugs were associated to an increased risk of mortality in patients with urinary sepsis associated to upper urinary tract calculi.
