Interventional Radiology (IR) plays a vital role in diagnosing and treating kidney-related conditions through minimally invasive, image-guided procedures. These techniques help manage both acute and chronic renal issues, often avoiding the need for open surgery.
Common IR Procedures in Nephrology
Percutaneous Nephrostomy
Placement of a tube into the kidney to drain urine when the ureter is blocked (e.g., by stones, tumors, or strictures).
Ureteral Stenting
Insertion of a stent to bypass urinary tract obstructions and restore urine flow from kidney to bladder.
Renal Biopsy
Ultrasound- or CT-guided sampling of kidney tissue to diagnose glomerular or interstitial diseases.
Angioplasty/Stenting of Renal Arteries
Opens narrowed renal arteries to improve blood flow and control hypertension.
Embolization of Renal Tumors or AVMs
Blocks blood supply to renal tumors or arteriovenous malformations (useful before surgery or to control bleeding).
Dialysis Access Interventions
Maintenance or salvage of AV fistulas or grafts in dialysis patients (e.g., angioplasty, thrombectomy).
