title: [Lumbar eventration as complication of the lumbotomy in the flank: review of our series].
abstract: OBJECTIVE
  To study the prevalence and risk factors of the lumbar eventration after lumbotomy in the flank.
  
  
  METHODS
  Survey of 230 patients that underwent lumbotomy in the flank, with a least followup of two years. Statistical study: contingency 2 x 2 tables (Pearson's chi 2 or Fisher exact test) to compare qualitative variables, Student's test to compare quantitative variables, Kaplan-Meier test and comparison of Log-rank curves. For the study of clinical variables with more influence in postoperative lumbar eventration, a logistic regression model was used.
  
  
  RESULTS
  The prevalence of postoperative lumbar eventration was 31.3%. Clinical variables more influence for postoperative lumbar eventration are: age, deficit of proteins, wound infection and haematoma of the abdominal wall.
  
  
  CONCLUSIONS
  Eventration is one the most frequent complications in urologic surgery and is of primary importance due to its laboral, economic and social implications.
