AB Interventional  uroradiologic  procedures  can  be  divided  into  two  major  groups:  vascular  and  percutaneous  nonvascular.  Percutaneous  nonvascular  interventional  procedures  are  discussed  elsewhere.  The  intravascular  route  is  used,  as  the  therapy  of  choice,  for  the  embolization  of  arteriovenous  fistulas  (AVFs)  or  malformations,  and  for  bleeding  sites.  Transcatheter  embolization  is  used  for  tumor  embolization,  for  the  ablation  of  renal  function,  for  the  treatment  of  testicular  vein  and  ovarian  vein  varices,  and  for  the  treatment  of  high-flow  priapism  (Ginat  et  al,  2009).  Balloon  angioplasty  and  stenting  of  stenotic  renal  arteries  are  frequently  performed  endovascular  techniques  for  the  treatment  of  ischemic  nephropathy  and  secondary  hypertension.  Renal  artery  aneurysms  may  also  be  treated  using  catheter-directed  techniques  such  as  stent  grafting  and  selective  embolization.  Occasionally,  fibrinolytic  agents  are  delivered  via  an  endovascular  catheter  to  thrombosed  renal  arteries.  Mechanical  devices  are  also  available  for  endovascular  treatment  of  thrombosed  renal  vessels.  This  chapter  will  review  these  intravascular  interventions.
