It seems like you're referring to "caudal epidurolysis" performed using a Racz catheter. Caudal epidurolysis, also known as caudal epidural neuroplasty or Racz procedure, is a minimally invasive procedure used to treat chronic low back pain or leg pain (sciatica) caused by conditions such as herniated discs, spinal stenosis, or failed back surgery syndrome. Here's how the procedure typically works: Preparation: Before the procedure, the patient may undergo a physical examination and imaging tests such as MRI or CT scans to identify the source of pain and ensure that caudal epidurolysis is an appropriate treatment option. Positioning: The patient usually lies face down on an examination table. The lower back area is cleaned and sterilized, and local anesthesia is administered to numb the skin and tissues. Catheter Placement: Using fluoroscopic guidance (live X-ray imaging), a special type of catheter known as a Racz catheter is inserted through the sacral hiatus (a natural opening in the sacrum) into the epidural space in the lower back. Medication Delivery: Once the catheter is properly positioned, a combination of medications, including a corticosteroid to reduce inflammation and a local anesthetic to provide pain relief, is injected into the epidural space. Mechanical Adhesiolysis: The Racz catheter is equipped with multiple side holes near its tip. By rotating and moving the catheter back and forth, the physician can mechanically break up adhesions (scar tissue) and fibrous tissue within the epidural space, which may be compressing nerves and causing pain. Rinsing: Saline solution may be injected through the catheter to flush out any debris or inflammatory substances from the epidural space, further reducing irritation to the nerves. Post-procedure: After the procedure, the patient may be monitored for a short period to ensure there are no immediate complications. Some patients may experience temporary soreness or numbness in the lower back or legs, but this typically resolves within a few hours. Caudal epidurolysis with a Racz catheter is considered a safe and effective treatment option for many patients with chronic low back pain or sciatica who have not found relief from conservative therapies such as medication, physical therapy, or spinal injections. It offers several potential benefits, including long-lasting pain relief, improved mobility, and reduced reliance on pain medications. However, like any medical procedure, it carries some risks, including infection, bleeding, nerve damage, or temporary worsening of pain. It's important for patients considering caudal epidurolysis with a Racz catheter to discuss the potential benefits and risks with their healthcare provider and to ensure that they are a suitable candidate for the procedure based on their individual condition and medical history.
