title: Factors associated with adverse outcome following urologic surgery in patients aged 80 years and older.
abstract: OBJECTIVE
  This study was designed to find predictors for adverse post-operative outcomes in elderly patients aged 80 years and older, who underwent urologic surgery.
  
  
  METHODS
  In this prospective observational study, we analysed data, including age, gender, American Society of Anesthesiologists (ASA) class, co-morbidities, number of regular medications, type and extent of surgery, type of anesthesia, duration of surgery and hospitalization, post-operative morbidity and mortality. We studied the correlations between each pre- and intra-operative parameter to the consequence, to find predictors for adverse outcome.
  
  
  RESULTS
  During a 12-month period, 217 patients underwent 294 urologic procedures in our institution. Ninety-eight procedures (33%) were followed by complications and 11 patients (5%) died. Patients who had uneventful surgery and hospitalization were significantly younger than those who experienced morbidity or mortality. There was a significantly higher complication rate among patients with a higher ASA class or with ischemic heart disease, following higher graded or longer operations, and after emergency surgery.
  
  
  CONCLUSIONS
  Older age is a significant risk factor. Patients with higher ASA class or ischemic heart disease are at higher risk for post-operative complications and thus, require careful follow-up. In this age population, extensive or prolonged surgery should be carefully considered.
