X-Ray RGU (Retrograde Urethrogram)

Overview

X-Ray RGU (Retrograde Urethrogram) is a specialized contrast-enhanced radiographic examination used to evaluate the urethra, the tube that carries urine from the bladder out of the body. During the procedure, contrast dye is gently introduced into the urethra, and X-ray images are obtained to assess its structure and function. This examination is commonly performed to diagnose urethral strictures, urethral injuries, blockages, fistulas, and other abnormalities affecting the urinary tract.

RGU is widely used in urology to provide detailed imaging of the anterior and posterior urethra, helping physicians identify the location and severity of urethral abnormalities.

Benefits of the Test

• Provides detailed visualization of the urethra.
• Helps diagnose urethral strictures and narrowing.
• Detects urethral injuries and trauma.
• Evaluates urinary tract abnormalities.
• Identifies urethral fistulas and leaks.
• Supports urological treatment planning.
• Offers accurate anatomical assessment.
• Helps guide surgical and interventional procedures.

Why Doctors Recommend This Test

• Investigation of difficulty passing urine.
• Diagnosis of urethral strictures.
• Assessment of urethral trauma.
• Evaluation of urinary obstruction.
• Investigation of recurrent urinary infections.
• Assessment before urological surgery.
• Follow-up of urethral repair procedures.

Preparation Before the Test

• Follow your doctor's instructions before the examination.
• Inform the healthcare team about any urinary infections.
• Inform the doctor if you have contrast allergies.
• Carry previous urology reports and imaging studies.
• Maintain adequate hydration unless instructed otherwise.
• Follow procedural instructions carefully.

Who Should Take This Test?

• Patients with difficulty urinating.
• Individuals with suspected urethral strictures.
• People with urethral injuries or trauma.
• Patients with recurrent urinary tract infections.
• Individuals with urinary obstruction symptoms.
• Patients referred by urologists.
• People requiring pre-operative urethral assessment.

Normal Reporting Time

Reports are typically available within 4 to 6 Hours after completion of the examination and radiologist review.

Detailed Information

Retrograde Urethrogram (RGU) is one of the most important imaging procedures used to evaluate the urethra. During the examination, a contrast agent is introduced into the urethral opening, and X-ray images are captured as the contrast fills the urethral channel. This allows detailed visualization of the urethral anatomy and helps identify abnormalities affecting urine flow.

The examination is particularly useful for diagnosing urethral strictures, which are areas of narrowing that can obstruct urine flow and cause symptoms such as weak urinary stream, urinary retention, and recurrent infections. RGU helps determine the exact location, length, and severity of the stricture.

RGU can also identify urethral injuries caused by trauma, pelvic fractures, surgical complications, infections, and inflammatory conditions. It is frequently performed before reconstructive urethral surgery and for follow-up evaluation after treatment.

Urologists commonly recommend this examination when evaluating lower urinary tract symptoms, urethral trauma, or suspected structural abnormalities. Although mild discomfort may occur during contrast administration, the procedure is generally safe and well tolerated.

Early diagnosis through X-Ray RGU helps guide effective treatment, improve urinary function, prevent complications, and support successful management of urethral disorders. It remains a valuable diagnostic tool in modern urological practice.
