Rgu X-Ray Scan

A RGU X-Ray Scan (retrograde urethrogram) is a specialised imaging test that checks the urethra for blockages, injuries, and other problems. Using a small amount of contrast dye and low-dose X-rays, the test gives your doctor a detailed roadmap of the urinary passage—all completed at Cadabams Diagnostics without the need for hospital admission.

Definition of retrograde urethrogram imaging

An RGU X-Ray Scan is an outpatient fluoroscopy study where contrast dye is gently introduced into the urethra through a thin catheter. X-ray images are taken while the dye travels upward, outlining every curve and contour of the urinary passage.

How contrast dye highlights the urethra

• The iodinated dye appears bright white on X-ray film.
• Any narrowing (stricture), leaks (fistula), or abnormal pouches (diverticula) stand out instantly.
• The whole process is monitored in real time, ensuring nothing is missed.

• Standard retrograde urethrogram: Static images capture the urethra in detail.
• Dynamic RGU with video fluoroscopy: Real-time motion study reveals stricture movement and sphincter function.

• Urethral diameter at multiple points
• Presence of stricture length and location
• Bladder neck competence
• Any contrast leakage outside the urethra
• Post-void residual contrast (optional)

• Investigating poor urine flow in men: Identify strictures or enlarged prostate effects.
• Post-trauma evaluation: Road accidents or pelvic fractures can injure the urethra.
• Pre-surgical planning: Surgeons use the images to decide the best approach for stricture repair.

Symptoms indicating the test

• Weak or interrupted urine stream
• Painful urination (dysuria)
• Blood in urine (haematuria) after injury
• Repeated urinary tract infections in men

Age & gender eligibility

• Adult men (18 years and above) are the primary candidates.
• Adult women may need an RGU in rare trauma cases.
• Children require paediatric urologist clearance—available on request at Cadabams Diagnostics.

• Quick 15-minute procedure—no hospital stay.
• High-resolution imaging with 3D reconstruction options.
• Same-day digital reports accessible on phone or email.
• Minimal discomfort—local anaesthetic gel is applied.

• Urethral stricture (scar narrowing)
• Urethral fistula (abnormal connection)
• Bladder neck obstruction (blockage at outlet)
• Diverticula, stones, or foreign bodies

• Fasting & hydration guidelines: Fast for 2 hours; drink one glass of water to keep kidneys active.
• Clothing & jewellery advice: Wear loose cotton clothes; remove metal zippers and chains.

• Recent urine routine & culture report (within 7 days).
• List of current medications.
• Signed consent form available at Cadabams Diagnostics.

• Morning slots (7 am – 11 am) reduce waiting times.
• Avoid during active UTI: Finish antibiotic course first.

• Adults 18+
• Contraindications:
• Known pregnancy
• Severe previous anaphylaxis to iodinated contrast

1. Check-in at Cadabams Diagnostics reception.
2. Change into provided gown; personal belongings secured.
3. Lie on the X-ray table; a nurse cleans the area.
4. Local anaesthetic gel applied; soft catheter inserted.
5. Contrast dye injected slowly while X-rays are taken.
6. Catheter removed; optional post-void film.
7. Dress and collect digital report link within 2 hours. Duration & positioning: 10–15 minutes; supine with legs slightly apart.

• Inform the technician if you have diabetes or kidney issues.
• Mention any allergy to shellfish or iodine.
• If you feel discomfort, raise your hand—staff will pause immediately.

• Low radiation exposure: Comparable to a chest X-ray.
• Allergy to contrast dye: Rare; inform staff of any previous reactions.
• When alternative imaging is preferred: Severe urethral infection or pregnancy—MRI or ultrasound may be advised instead.
