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