Summary
Percutaneous renal cryoablation using local anesthesia is effective for most patients, minimizing the need for intravenous sedation. This approach offers a safe and comfortable alternative for treating kidney tumors.
Area of Science:
- Interventional Radiology
- Nephrology
- Oncology
Background:
- Intravenous sedation during percutaneous procedures carries potential complications.
- Minimizing sedation can improve patient safety and procedural efficiency.
Purpose of the Study:
- To assess the pain experienced during computed tomography (CT)-guided percutaneous renal cryoablation using local anesthesia.
- To evaluate the feasibility and safety of performing renal cryoablation with local anesthesia alone.
Main Methods:
- Patients underwent CT-guided percutaneous renal cryoablation with local anesthesia.
- Pain was rated on a 10-degree scale; sedation was administered if pain exceeded 7 or upon patient request.
- Cardiopulmonary complications, need for IV supplementation, and pain scores were assessed.
Main Results:
- 84.62% of 26 cryoablation sessions were completed successfully using only local anesthesia.
- The mean pain score was not explicitly stated, but only four patients required intravenous supplementation.
- No significant changes in vital signs were observed during the procedures.
Conclusions:
- CT-guided percutaneous renal cryoablation can be safely performed using local anesthesia.
- Most patients experience minimal discomfort, reducing the need for intravenous sedation.

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...
01:16Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia
Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
