Can cystoscopy diagnose bladder stones?

Yes. Cystoscopy can directly diagnose bladder stones by allowing a urologist to examine the inside of the bladder with a small camera. It can also help identify other abnormalities in the urethra and bladder that may be contributing to urinary symptoms or stone formation. In suitable cases, the stone can also be treated during an endoscopic procedure.

Cystoscopy is an endoscopic procedure in which a thin instrument called a cystoscope is passed through the urethra into the bladder.

The cystoscope has a camera or optical system that allows the urologist to directly inspect the urinary passage and bladder.

Can cystoscopy clearly show a bladder stone?

Yes. Because the urologist can directly see inside the bladder, cystoscopy can identify:

• Bladder stones.
• The number of stones.
• Approximate stone size.
• Stone location.
• Bladder lining abnormalities.
• Other structural problems.

How is cystoscopy performed?

During cystoscopy:

1. Appropriate anesthesia or local numbing medication is provided depending on the procedure.
2. The cystoscope is gently passed through the urethra.
3. It is advanced into the bladder.
4. The bladder is examined from inside.
5. If a stone is identified, the urologist can determine the appropriate treatment.

The exact technique depends on the patient's condition and the reason for the cystoscopy.

Can cystoscopy treat a bladder stone as well as diagnose it?

Yes, in appropriate cases. When a bladder stone requires removal, the urologist may perform an endoscopic stone-removal procedure such as cystolitholapaxy.

The stone can be fragmented using an appropriate technique, such as laser energy, and the fragments can then be removed through the urinary passage.

Why might cystoscopy be recommended if an ultrasound has already been done?

Ultrasound can identify many bladder stones, but cystoscopy provides direct visualization of the bladder and urethra.

It may be useful when:

• Imaging findings are unclear.
• Urinary symptoms persist.
• A bladder abnormality needs direct assessment.
• The urologist needs to examine the urethra.
• Treatment is being planned.

The need for cystoscopy depends on the individual clinical situation.

Can cystoscopy identify the cause of bladder stone formation?

It can identify some structural abnormalities, but it does not determine every cause.

For example, cystoscopy may help identify abnormalities involving the bladder or urethra.

Additional evaluation may be needed for conditions such as:

• Enlarged prostate.
• Incomplete bladder emptying.
• Bladder dysfunction.
• Recurrent urinary infection.
• Other urinary obstruction.

Can cystoscopy detect urethral stricture?

Yes. Cystoscopy can allow the urologist to examine the urethra and may identify a narrowing or stricture.

This can be particularly relevant when a patient has both a bladder stone and difficulty passing urine.

Can cystoscopy detect bladder problems besides stones?

Yes. Direct examination may identify abnormalities involving the bladder lining or other structural changes.

If an abnormal area is seen, further evaluation may be recommended depending on the findings.

Is cystoscopy painful?

The level of discomfort depends on the type of cystoscopy and anesthesia or local numbing used.

Patients may experience temporary:

• Burning while urinating.
• Urinary frequency.
• Mild urethral discomfort.

Your urologist will explain what to expect before the procedure.

Is Cystoscopy Better Than Ultrasound for Bladder Stones?

They serve different purposes.

Ultrasound is non-invasive and can detect many bladder stones while also helping assess residual urine.

Cystoscopy provides direct visualization of the urethra and bladder and may allow treatment during the same endoscopic procedure.

Your urologist will decide which test is appropriate based on your symptoms and clinical findings.

Is Cystoscopy Better Than a CT Scan?

Not necessarily. CT provides detailed cross-sectional images of the urinary tract, while cystoscopy allows direct examination of the inside of the urethra and bladder.

The appropriate investigation depends on what your doctor needs to determine.

Can Cystoscopy Be Used After Bladder Stone Surgery?

Yes, in selected cases. Depending on symptoms, previous treatment, and clinical findings, cystoscopy may be used to evaluate the bladder or urethra after treatment.

Routine cystoscopy is not necessarily required for every patient.

When Should I See a Urologist?

Consider a urological evaluation if you have:

• Blood in the urine.
• Burning or painful urination.
• Frequent urination.
• Urinary urgency.
• Weak urine flow.
• Difficulty emptying the bladder.
• Recurrent urinary infections.
• A known or suspected bladder stone.
• Recurrent bladder stones.

Sudden inability to pass urine requires prompt medical attention.

SCI International Hospital

At SCI International Hospital, New Delhi, Dr. Gautam Banga, Senior Consultant Urologist and Andrologist, evaluates patients with bladder stones, urinary obstruction, enlarged prostate, urethral stricture, recurrent urinary infections, and incomplete bladder emptying. When clinically appropriate, cystoscopy can help directly examine the urethra and bladder and assist in planning minimally invasive treatment.
