title: Laparoscopic retrieval of a migrated Amplatz sheath.
abstract: OBJECTIVE
  Percutaneous nephrolithotomy is a relatively safe technique. However, it is not exempt from complications, some of which can be severe and even fatal. Some complications may be plausible for laparoscopic management. We report our experience in the management of a rare complication by laparoscopic means.
  
  
  METHODS
  We report the case of an Amplatz sheath that inadvertently migrated out of the renal parenchyma during a percutaneous nephrolithotomy. Patient data, procedure conditions, and laparoscopic retrieval of the sheath are detailed.
  
  
  RESULTS
  The Amplatz sheath was successfully retrieved laparoscopically. Total operative time was 180 minutes. Operative bleeding was minimal. The postoperative period was uneventful, and the patient was discharged on postoperative day 3.
  
  
  CONCLUSIONS
  Laparoscopy must be regarded as an option for the management of a surgical complication, especially if a minimally invasive approach is to be kept.
