Injection procedure for cystography or voiding urethrocystography

CPT4 code

Name of the Procedure:

Injection Procedure for Cystography or Voiding Urethrocystography (VCUG)

Summary

This procedure involves injecting a contrast dye into the bladder to take X-ray images. It helps doctors visualize the bladder and urethra to diagnose and assess urinary tract issues.

Purpose

Cystography and voiding urethrocystography are used to:

  • Diagnose bladder and urethra conditions such as vesicoureteral reflux, bladder rupture, or anatomical abnormalities.
  • Evaluate symptoms like recurring urinary tract infections (UTIs), incontinence, or blood in the urine.
  • Assess the bladder's function and structure, especially after trauma or surgery.

Indications

  • Recurrent UTIs
  • Unexplained incontinence or urinary urgency
  • Blood in urine (hematuria)
  • Traumatic injury to the lower abdomen
  • Pre-surgical assessment for bladder-related procedures

Preparation

  • The patient may need to stop taking certain medications and inform the doctor of any allergies, especially to contrast dye.
  • Typically, no fasting is required.
  • A preliminary urinalysis may be conducted to check for existing infections.

Procedure Description

  1. The patient lies on an X-ray table.
  2. The genital area is cleansed with an antiseptic solution.
  3. A thin catheter is gently inserted into the urethra and advanced into the bladder.
  4. Contrast dye is slowly injected through the catheter to fill the bladder.
  5. X-ray images are taken while the bladder is filling and during urination to capture the entire process.
  6. The catheter is then removed.

Tools: Sterile catheter, contrast dye, antiseptic solution. Anesthesia: Local anesthesia may be applied to the urethra to minimize discomfort; sedation is generally not required.

Duration

The entire procedure typically takes about 30-60 minutes.

Setting

This procedure can be performed in a hospital radiology department or an outpatient imaging center.

Personnel

  • Radiologist or urologist
  • Radiology technician
  • Nurses

Risks and Complications

Common risks:

  • Mild discomfort or burning sensation during urination post-procedure
  • Allergic reaction to the contrast dye

Rare complications:

  • Urinary tract infection
  • Bleeding or injury to the urethra or bladder

Benefits

  • Precise diagnosis of urinary tract conditions.
  • Helps guide appropriate treatments.
  • Non-invasive with quick recovery.

Recovery

  • Patients can usually return to normal activities immediately.
  • Drink plenty of fluids to help flush out the contrast dye.
  • Mild pain relievers can be used if needed.
  • Follow-up appointment if any abnormalities are found.

Alternatives

  • Ultrasound (less detailed but no exposure to contrast dye)
  • MRI (does not use X-rays but may not be as accessible)
  • CT scan (provides detailed images but involves higher radiation exposure)

Patient Experience

During the procedure:

  • Expect mild discomfort during catheter insertion.
  • A sensation of fullness or urge to urinate as the bladder fills.

After the procedure:

  • Some burning sensation during urination, which should subside within a day.
  • Follow post-procedure care instructions for optimal recovery.
