Name of the Procedure:

Dilation of Existing Tract, Percutaneous for an Endourologic Procedure with Imaging Guidance (e.g., Ultrasound, Fluoroscopy) and Postprocedure Tube Placement

Summary

This procedure involves widening an existing tract within the body to allow for an endourologic procedure. It is performed through the skin (percutaneously) with the assistance of imaging technologies such as ultrasound or fluoroscopy. The procedure also includes the placement of a tube post-procedure to ensure proper drainage or access.

Purpose

The procedure is used to treat urinary tract obstructions, stones, or other related conditions by providing a pathway for treatment instruments. The goal is to facilitate endourologic interventions and ensure proper drainage or access afterward.

Indications

• Urinary tract stones that cannot be passed naturally
• Obstruction within the urinary tract
• Need for repeated access to the urinary tract for treatment or drainage
• Conditions requiring continuous urine drainage

Preparation

• Patients may be instructed to fast for a certain number of hours before the procedure.
• Medications may need to be adjusted, especially blood thinners.
• Pre-procedure imaging tests such as ultrasounds or CT scans might be required to plan the procedure.
• Arrangements for post-procedure transportation and care should also be made.

Procedure Description

1. The patient is positioned appropriately and an area of skin is cleaned and sterilized.
2. Local anesthesia or sedation is administered to minimize discomfort.
3. Imaging guidance (ultrasound or fluoroscopy) is used to visualize the existing tract.
4. A guidewire is inserted into the tract, followed by the gradual dilation using specialized dilators.
5. Once the tract is sufficiently widened, the needed endourologic procedure is performed.
6. A tube is placed within the tract to maintain patency and facilitate drainage post-procedure.
7. Imaging guidance confirms proper tube placement, and dressings are applied.

Duration

The procedure typically lasts between 30 minutes to 1 hour, depending on the complexity.

Setting

It is usually performed in a hospital or an outpatient surgical center equipped with imaging facilities.

Personnel

• Urologist or Endourologist
• Radiologist
• Nurses
• Anesthesiologist or sedation nurse

Risks and Complications

• Infection at the puncture site
• Bleeding or hematoma formation
• Injury to surrounding organs or tissues
• Allergic reactions to anesthesia or contrast agents
• Possible need for additional interventions if complications arise

Benefits

• Immediate relief from obstruction-related symptoms
• Facilitates further diagnosis and treatment of urinary tract conditions
• Ensures proper drainage or access for future treatments

Recovery

• Patients may need to stay in recovery for a few hours to monitor for immediate complications.
• Pain and discomfort are typically managed with medications.
• Instructions regarding activity restrictions, wound care, and tube maintenance will be provided.
• Follow-up appointments are essential to monitor the tract and tube placement.

Alternatives

• Traditional open surgical procedures to address urinary tract conditions
• Medical management, such as medications to dissolve stones
• Non-invasive procedures like extracorporeal shock wave lithotripsy (ESWL) for stone removal
• Each alternative has its pros and cons, such as increased recovery time for surgery vs. varying effectiveness for non-invasive methods.

Patient Experience

• Mild discomfort or pressure may be felt during the procedure due to the dilation process.
• Post-procedure, there might be some pain at the puncture site, manageable with prescribed pain relief.
• Patients may experience temporary changes in urination patterns or slight blood in urine, which typically resolves.
• Efficient post-operative care and adherence to instructions will enhance recovery and minimize discomfort.
