title: Simple one-step catheter placement for the treatment of infected lymphocele.
abstract: OBJECTIVE
  A pelvic lymphocele is a cystic collection of lymph fluid in the pelvis following pelvic lymphadenectomy. This retrospective study was undertaken to show the efficacy and safety of simple one-step catheter placement for the treatment of infected lymphocele.
  
  
  METHODS
  Ten infected lymphoceles were treated in nine patients. The percutaneous drainage procedures were performed using simple one-step trocar technique under sonographical guidance. The one-step pig tail catheter system consists of an 18-gauge needle, stylet, and 7F drainage tube. A 33% povidone-iodine solution was instilled and left in the cavity for 30 min twice daily.
  
  
  RESULTS
  Overall, 9 of the 10 infected lymphoceles were successfully treated with one-step catheter drainage. Percutaneous catheter drainage was maintained for 2-17 days. One of the patients required open surgery for the persistence of infected lymphocele due to the catheter dislodgment. No patients encountered sepsis, bowel perforation, and neurovascular injury.
  
  
  CONCLUSIONS
  Simple one-step procedure enables long-term drainage and is a well-tolerated, safe, and effective technique in the management of infected lymphocele.
