title: [Renal hematoma as a result of internal ureteral catheterization].
abstract: OBJECTIVE
  Urinary catheterization by means of an internal ureteral catheter in an usual procedure that may present complications. In this article we presented a case of perforation and later renal subcapsular hematoma after the placement of a "double-J" catheter.
  
  
  CONCLUSIONS
  This complication, although rare, should be kept in mind. The manner of avoiding it is to maintain the tightness of the guidewire while inserting the ureteral catheter. Usually, the consequences are not life-threatening and are solved with conservative treatment. The administration of LFRE should be delayed until the resolution of the hematoma.
