Radionuclide Cystography (DRCG / Indirect) Hyderabad | Focus Diagnostics

About Radionuclide Cystography (DRCG / Indirect)

Radionuclide Cystography is a nuclear medicine imaging procedure used to evaluate vesicoureteral reflux (VUR), a condition in which urine flows backward from the urinary bladder toward the ureters and kidneys. The examination uses a radioactive tracer and gamma camera imaging to assess urinary flow.

Indirect radionuclide cystography involves intravenous administration of a suitable radiotracer, followed by imaging as the tracer passes through the kidneys into the urinary bladder. The examination can help identify reflux during bladder filling or urination.

What Does Radionuclide Cystography Evaluate?

This nuclear medicine examination evaluates the movement of urine through the urinary system and helps detect abnormal backward flow from the bladder into the ureters or kidneys. It provides functional information that may support the assessment of vesicoureteral reflux.

Why Is Radionuclide Cystography Performed?

Doctors may recommend radionuclide cystography for selected patients with suspected vesicoureteral reflux, recurrent urinary tract infections, previously diagnosed urinary reflux or urinary tract abnormalities. It may also be considered for follow-up evaluation when clinically indicated.

The choice of indirect or direct radionuclide cystography depends on the patient's clinical condition, age, ability to cooperate with the examination and the referring doctor's recommendation.

How Is Indirect Radionuclide Cystography Performed?

A suitable radiotracer is administered intravenously under the supervision of the nuclear medicine team. The tracer is filtered by the kidneys and passes into the urinary bladder. Gamma camera images are obtained according to the prescribed imaging protocol.

The patient may be asked to urinate during image acquisition to evaluate whether tracer-containing urine flows backward toward the ureters or kidneys. The exact examination procedure and duration depend on the clinical indication and imaging protocol.

Preparation for Radionuclide Cystography

Patients should follow the preparation instructions provided by the nuclear medicine team. Specific instructions may include hydration or bladder preparation depending on the examination protocol.

• Inform the medical team about current medications and relevant medical conditions.
• Share previous urinary tract imaging reports and relevant medical records.
• Inform the team about pregnancy, possible pregnancy or breastfeeding where applicable.
• Follow instructions regarding fluid intake and bladder emptying.
• Do not stop prescribed medications unless advised by the treating doctor.

Benefits of Radionuclide Cystography

Radionuclide cystography provides functional imaging information about urinary reflux. It may help doctors identify vesicoureteral reflux and evaluate urinary flow abnormalities in appropriate clinical situations.

The examination may be useful for selected follow-up assessments. However, it does not replace every other urinary tract imaging procedure, and its suitability depends on the clinical question.

Understanding the Radionuclide Cystography Report

The nuclear medicine report may describe the presence or absence of vesicoureteral reflux, the side involved and the observed pattern of radiotracer movement. Findings are interpreted by a qualified nuclear medicine physician along with clinical history and other investigations.

Frequently Asked Questions

What is Radionuclide Cystography?

Radionuclide cystography is a nuclear medicine imaging procedure used to evaluate backward flow of urine from the bladder toward the ureters and kidneys.

What is indirect radionuclide cystography?

Indirect radionuclide cystography uses an intravenously administered radiotracer that passes through the kidneys into the bladder. Gamma camera imaging helps evaluate urinary reflux.

Why is a DRCG scan recommended?

It may be recommended to evaluate suspected vesicoureteral reflux, recurrent urinary tract infections or selected urinary tract abnormalities.

Does radionuclide cystography use radiation?

Yes. The procedure uses a radioactive tracer and involves ionising radiation exposure. The nuclear medicine team selects an appropriate imaging protocol.

Is preparation required?

Preparation depends on the examination protocol. Patients should follow the instructions provided by the nuclear medicine team.

How long does the scan take?

The examination duration varies depending on tracer passage, bladder filling, urination and the prescribed imaging protocol.

What is the difference between direct and indirect radionuclide cystography?

Direct radionuclide cystography generally introduces a radiotracer into the bladder through a urinary catheter. Indirect radionuclide cystography uses an intravenously administered radiotracer that reaches the bladder through the kidneys.
