      Shoji and colleagues retrospectively compared background factors in iliopsoas abscess patients who underwent conservative treatment and found that the large abscess size predicted treatment failure [

      ]. The abscess size is a variable that imaging studies can easily evaluate, and this study would advance the understanding of surgical indications for iliopsoas abscesses. In addition to the abscess size, other factors, such as end-stage renal disease and immunosuppression, were also associated with the conservative treatment failure. These factors would also be useful to judge surgical indications in clinical settings. However, we would like to discuss one issue of this research: a potential difference in the types of causative organism(s) between the success (S) and failure (F) groups.
