Renal and Urologic Interventions

Renal Interventions

1. Renal Artery Stenosis Treatment
1. Initial MRA to assess renal artery flow
2. Angiogram with stenting and/or angioplasty of the renal arteries to treat stenosis causing recurrent hypertension and FMD
2. Placement of dialysis access catheters
1. Temporary access for immediate dialysis
2. Semi-permanent access for continued dialysis
3. AV Graft Declotting
1. Careful removal of thrombus in AV Grafts that forms normally with repeated use.
2. Stents placed in persistently narrowed areas.
4. Fistula evaluation and Treatment
1. Fistulagrams to initially evaluate flow.
2. Angioplasty of narrowed segments
3. Cryoplasty (angioplasty with a special balloon that freezes the vessel) in recurrent narrowed segments.
4. Cutting Balloons (balloons with blades that cut plaque) used in highly resistive narrowed areas.
5. Central Venous Evaluation
1. Venography with venoplasty of central occlusions that often arise from repeated subclavian venous access.
6. Pre-surgical Embolization
1. Entire arterial bed of kidney can be embolized prior to planned surgical removal

• Useful in cases of highly vascular tumors or when significant blood loss is anticipated.
• Nephrostomy Tubes
• Ureteral Stents
• Dialysis Access
  • Tunneled Permanent Lines
• Temporary Central Lines
• AV Graft Declotting
• AV Fistula Angioplasty
• Renal Embolization (pre-surgical)

Urology

Working in conjuction with urologists, IR can serve a role in safe and comprehensive management of urologic disease.

• Nephrostomy tubes
• Ureteral Stents
• Suprapubic catheters

Hepatobiliar, Hpatic Disease

• Percutaneous Transhepatic Cholangiography
• Percutaneous Transhepatic Biliary Drains
• Percutaneous Biliary Stents
• Trans-jugular Liver Biopsies
• TIPS (Trans-jugular Intrahepatic Portosystemt Shunt)
• Cholecystostomy Tubes

Oncology

• Chemoembolization of Hepatic Tumors
• Radiofrequency Ablation of Hepatic, Renal, or Lung Tumors
• Yittrium-90 (Therasphere) Ablation of Hepatic Tumors
• Chest Port Placement
