Cystoscopy: what to expect during the exam

A cystoscopy is an important urological examination in which the inside of the bladder is viewed directly with a thin instrument. It is used to investigate symptoms such as blood in the urine, recurring bladder infections, or suspected bladder stones and tumors. The exam usually takes only a few minutes and is typically performed on an outpatient basis with local anesthesia. Thanks to modern flexible instruments and numbing gel, most people tolerate a cystoscopy well. Afterwards, mild burning during urination or minimal traces of blood in the urine can occur and normally clear up within one to two days.

You have a cystoscopy scheduled and are wondering what to expect? That is a common feeling — and the exam usually sounds more unpleasant than it actually is. Let's walk through what a cystoscopy is, when it becomes necessary, and how it works.

What is a cystoscopy?

A cystoscopy is an examination in which your doctor looks directly at the inside of your bladder and urethra.¹ It uses a thin, tube-shaped instrument with a small camera at its tip, called a cystoscope.

That may take some getting used to, but the technology has advanced considerably in recent years. Modern cystoscopes are much thinner and more flexible than they used to be, which makes the exam more comfortable.²

Why is a cystoscopy performed?

Your doctor does not recommend a cystoscopy without reason. There are several medical situations in which the exam is useful or even necessary:

Blood in the urine is one of the most common reasons. If blood appears in your urine — whether visible or only detectable in a lab test — your doctor will want to find the cause.³ It can have harmless explanations, but more serious conditions can also be behind it.

Recurring bladder infections can be another reason. If you keep struggling with urinary tract infections (UTIs), a cystoscopy allows your doctor to look for possible underlying causes.³

Problems with urination such as pain, difficulty urinating, or frequent urination can be caused by various changes in the bladder or urethra. A cystoscopy can help pinpoint the exact cause.³

Suspected bladder stones or bladder cancer also makes the exam necessary. For bladder cancer, cystoscopy is used not only for diagnosis but also for follow-up monitoring after treatment.⁴

Follow-up exams after bladder cancer are particularly important, because the disease can unfortunately recur. Regular cystoscopies are then a standard part of the follow-up program.⁴

How does the exam work?

Here is what to expect during a cystoscopy, step by step.

Before the exam, you will be asked to empty your bladder. A sterile drape is placed over the genital area and the opening of the urethra is thoroughly disinfected.⁵ The medical staff do this routinely and will try to make the situation as comfortable as possible for you.

The urethra is numbed with a local anesthetic gel that also acts as a lubricant.⁵ It can feel a little cool, but it makes the actual exam much more tolerable.

During the exam, the doctor carefully guides the cystoscope through the urethra into the bladder. The bladder is filled with a sterile fluid so the bladder wall unfolds and everything becomes clearly visible.⁵ This can cause a feeling of pressure or a mild urge to urinate — that is completely normal.

The doctor can then view the entire bladder lining and look for anything unusual. If needed, small tissue samples can be taken or minor procedures performed during the exam.⁵

After the exam, you can usually go straight home. It is completely normal to feel mild burning when urinating afterwards or to see a little blood in your urine.⁶ This should clear up within one to two days.

Does a cystoscopy hurt?

The question that is probably on your mind most: is the exam painful?

Honestly, everyone experiences it differently. Thanks to the numbing gel, most people find the exam uncomfortable rather than painful.⁵ Many describe a feeling of pressure or a mild urge to urinate during the procedure.

For men, the exam can be somewhat more uncomfortable than for women, because the male urethra is considerably longer and also passes through the prostate.⁵ Here too, the numbing gel provides relief.

If you are very anxious or find the exam particularly unpleasant, a cystoscopy can also be performed under light anesthesia or sedation.⁶ Talk to your doctor beforehand if you have concerns.

Are there different types of cystoscopy?

Yes, there are two basic variants:

Flexible cystoscopy uses a bendable cystoscope and is usually performed under local anesthesia. It is generally sufficient for diagnostic purposes — just looking — and is often done on an outpatient basis at a urology practice.²

Rigid cystoscopy is used when the goal is not only to look but also to treat — for example, when tissue samples need to be taken or bladder stones removed. This usually requires general anesthesia or at least deeper sedation, and the procedure takes place in a hospital.²

What are the risks?

As with any medical procedure, a cystoscopy carries possible risks — but overall they are rare:

Urinary tract infections can occur after the exam, even under strictly sterile conditions. That is why it is important to drink plenty of fluids afterwards to flush the bladder.⁶

Injuries to the urethra or bladder are very rare but can happen. Be sure to inform your doctor if you notice severe pain, fever, or persistent bleeding after the exam.⁶

Urinary retention — the inability to urinate — is also possible, but not common. If you cannot urinate after the exam despite feeling the urge, contact your doctor right away.⁶

What can a cystoscopy reveal?

The exam can make various changes and conditions visible:

Bladder stones can be identified directly and, depending on their size, removed during the exam.³

Tumors and growths in the bladder become visible. Bladder cancer often appears as small growths on the bladder lining that the doctor can see directly.⁴

Inflammation and irritation of the bladder lining become apparent. In chronic bladder infections, this can provide important clues about the cause.³

Narrowing of the urethra (strictures) or other anatomical variations can be identified and, if necessary, treated.³

How can I prepare?

The good news: there is not much you need to do.

Before the exam, you can eat and drink normally, unless anesthesia is planned — in that case, the usual fasting rules apply. If you take blood-thinning medication, discuss with your doctor whether to pause it beforehand.

On the day of the exam, wear comfortable clothing that is easy to take off and put back on. If no anesthesia is planned, you can drive as usual and do not need someone to accompany you.

After the exam, it is important to drink plenty of fluids. This helps flush out any bacteria and supports healing.⁶ Two to three liters spread over the day is ideal.

When should you contact your doctor after the exam?

In most cases everything goes smoothly, but there are a few warning signs you should not wait out:

• Fever above 38 °C (100.4 °F)
• Severe pain that does not respond to pain relievers
• Persistent heavier bleeding in the urine
• Inability to urinate
• Increasing pain during urination after two to three days⁶

In these cases, contact your doctor — or go to an emergency room if symptoms are severe.

Are there alternatives to cystoscopy?

Imaging methods such as ultrasound, CT, or MRI can show the bladder from the outside, but in many cases they cannot replace the direct view a cystoscopy provides.³ They can be used as a complement, but especially when bladder cancer is suspected or blood in the urine needs to be investigated, cystoscopy is often indispensable.

Urine tests can point to inflammation or other changes, but they do not show the full picture. They are important for diagnosis, but for certain questions they cannot replace a cystoscopy.⁴

Conclusion: no reason to worry

A cystoscopy is not a pleasant prospect, but for many questions it is the best available exam. Modern technology and effective anesthesia options make it generally well tolerated. If your doctor recommends a cystoscopy, there is a good medical reason for it — and the exam can often provide important clarity or even save a life.

Talk openly with your doctor about your concerns and questions. The better informed you are, the calmer you can go into the exam. And remember: after a few minutes it is over, and you have taken an important step for your health.
