Percutaneous vaso-occlusion for nonmalignant renal lesions
The Journal of Urology
|April 1, 1983
Summary
Transarterial renal embolization effectively treats various nonmalignant renal conditions, including hemorrhage and proteinuria, offering a surgical alternative for high-risk patients. Renal infection is a contraindication for this procedure.
Area of Science:
- Interventional Radiology
- Nephrology
- Vascular Surgery
Background:
- Transarterial renal embolization (TRE) is established for renal cancer management.
- Its utility in nonmalignant renal lesions requires further elucidation.
Observation:
- This study evaluated 9 patients undergoing selective/superselective TRE for benign renal conditions.
- Indications included hemorrhage from angiomas, pseudoaneurysms, post-biopsy, and adult polycystic kidney disease.
- TRE was also used for massive proteinuria in end-stage renal disease and severe hypertension in chronic renal failure.
Findings:
- Successful embolization was achieved in all 9 patients.
- Specific successes included treating hemorrhage, proteinuria, hypertension, and a postoperative arteriovenous fistula.
- Catheter vaso-occlusion was effective for the arteriovenous fistula.
Implications:
- TRE presents a viable, less invasive alternative to surgery for complex or high-risk benign renal lesions.
- It offers a potential treatment for proteinuria and hypertension in renal disease patients.
- Renal infection is a critical contraindication, necessitating careful patient selection.

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

01:19Imaging Studies VII: Vascular Imaging
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
