Sepsis after elective ureteroscopy.

We sought to determine our rate of postoperative sepsis after ureteroscopy as well as identifying associative factors, common antibiotic practices along with culture data.Records of all patients who underwent elective ureteroscopy from 2010 to 2015 at an urban tertiary care facility were retrospectively reviewed. Factors thought to be associated with infection were collected, along with comorbidities depicted as Charlson Age-Adjusted Comorbidity Index (CAACI) and American Society of Anesthesia (ASA) score. Each patient's course was reviewed to determine if they were treated for postoperative sepsis as defined by standardized criteria.A total of 345 patients underwent elective ureteroscopy with 15 (4.3%) being treated for sepsis postoperatively. This resulted in an additional 5.33 ± 3.84 days of hospitalization per patient. The sepsis group grew three gram positive organisms and five multi-drug resistant (MDR) gram negatives while 7/15 (46.7%) had negative cultures. The most common preoperative antibiotics used in the sepsis group were cefazolin (60.0%), gentamicin (48.5%) and ciprofloxacin (20.0%). Univariate analysis showed prior endoscopic procedures, recent treatment for urinary tract infections (UTI), multiple comorbidities and longer operative times associated with sepsis. However, significant variables after multivariate analysis were treatment for UTI within the last month, (OR) 7.19 (2.25-22.99), p = 0.001.Patients with multiple comorbidities, prior endoscopic procedures, longer operative times and especially those recently treated for a urinary infection should be carefully monitored after ureteroscopy for signs of sepsis. Perioperative antibiotics in these patients should be selected to cover both MDR organisms and gram positives.
