Risks and benefits of cystoscopy

Overview

A cystoscopy is a procedure that allows your doctor to look inside your bladder and the tube that carries urine out of your body (the urethra). It uses a thin, flexible tube with a tiny camera on the end, called a cystoscope, to see the lining of these organs. Your doctor may recommend a cystoscopy to find the cause of symptoms like blood in the urine, frequent bladder infections, or trouble urinating. It can also be used to take small tissue samples (biopsies) or remove small stones or growths.

Yes, cystoscopy is a very common procedure performed in hospitals and clinics worldwide. It is often used to investigate urinary symptoms or to check for bladder problems like stones, infections, or cancer.

People of any age or sex may need a cystoscopy if they have unexplained blood in the urine, repeated urinary tract infections, difficulty urinating, or other bladder symptoms. It is also used for monitoring conditions like bladder cancer or interstitial cystitis. The procedure is tailored to each person's needs and health status.

Symptoms

Common symptoms

• Blood in the urine (hematuria) – sometimes visible, sometimes only found on a urine test.
• Frequent or urgent need to urinate, often with little warning.
• Pain or burning when urinating (dysuria) that does not go away.
• Difficulty emptying your bladder fully or a weak urine stream.
• Repeated urinary tract infections (UTIs) that keep coming back.

Symptoms in children

• Blood in the urine.
• Repeated urinary tract infections.
• Trouble urinating or a weak stream.
• Bedwetting that continues past age 5-6 with other symptoms.
• Pain in the lower belly or back.

Symptoms in older adults

• Blood in the urine – always requires investigation in older adults.
• Sudden or frequent urge to urinate, especially at night.
• Difficulty starting urination or dribbling after finishing.
• Unexplained weight loss or pelvic pain along with urinary symptoms.
• Repeated urinary tract infections that do not respond to treatment.

Causes

Main causes

• Bladder stones – hard mineral deposits that can form in the bladder.
• Bladder infections (cystitis) that are recurrent or unusual.
• Bladder tumors or growths, which may be benign (non-cancerous) or malignant (cancerous).
• Enlarged prostate (in men) – pressing on the urethra and causing symptoms.
• Interstitial cystitis (also called painful bladder syndrome) – a condition with long-term bladder pain and urgency.
• Urethral stricture – narrowing of the urethra that blocks urine flow.

Risk factors

• Being over age 50, especially men (higher risk of prostate and bladder issues).
• Smoking – the single biggest risk factor for bladder cancer.
• Chronic bladder infections or long-term use of a catheter.
• Exposure to certain industrial chemicals (e.g., in the rubber, dye, or leather industries).
• Family history of bladder cancer or other urinary tract problems.
• Having had previous bladder surgeries or radiation to the pelvic area.

When to see a doctor

See a doctor urgently if:

• Any visible blood in your urine – even once.
• Pain when urinating that does not go away after a day or two.
• Frequent urinary tract infections that keep coming back.
• Sudden difficulty urinating or pain in your lower belly.

Book a routine appointment if:

• If you have been told to have a follow-up cystoscopy for a known condition (like bladder cancer or stones).
• If you have mild but persistent urinary symptoms that worry you.
• If your doctor recommended a cystoscopy as part of a check-up for bladder health.

Diagnosis

The need for a cystoscopy is usually determined after you have told your doctor about your symptoms and had basic tests like a urine dipstick or urine culture. If those tests suggest a bladder problem, or if you have blood in your urine that cannot be explained, your doctor may refer you to a specialist (urologist) who will perform the cystoscopy. The decision to do a cystoscopy is based on your medical history, symptoms, and risk factors.

Tests that may be done

• Urinalysis – a simple test on a urine sample to check for blood, infection, or other abnormalities.
• Urine culture – to see if you have a bacterial infection and which antibiotic might work.
• Ultrasound of the kidneys and bladder – an imaging test that uses sound waves to check for stones or structural problems.
• CT scan (computerized tomography) – a detailed X-ray that can show bladder stones, tumors, or other issues.

What to expect at your appointment

Before the procedure, you will be asked to empty your bladder. You will lie on a table with your knees bent and apart. The doctor will clean the area and apply a numbing gel to your urethra. A thin, flexible cystoscope is gently inserted into your urethra and up into your bladder. Your doctor may fill your bladder with sterile water to get a clearer view. You may feel a need to urinate or some pressure, but it should not be painful. The procedure usually takes 10-20 minutes. Afterward, you can go home. You may have some mild burning or blood-tinged urine for a day or two – this is normal. You should drink plenty of water to help flush your bladder.

Treatment

Cystoscopy is mainly a diagnostic test, but it can also be used for treatment. If your doctor finds a problem during the procedure, they may be able to fix it right away. Treatment depends on what is found. For example, small bladder stones can be removed with special instruments passed through the cystoscope. If a suspicious growth is seen, the doctor can take a biopsy (tiny tissue sample) for testing, or sometimes remove the growth completely. Your doctor will discuss the results and any further treatment you might need after the procedure.

Self-care at home

• Drink plenty of water for the next 24-48 hours to help flush your bladder and reduce discomfort.
• Take over-the-counter pain relief like paracetamol (acetaminophen) if you have mild discomfort – but check with your doctor or pharmacist first.
• Avoid heavy lifting, strenuous exercise, or sexual activity for 24 hours after the procedure.
• If you notice a small amount of blood in your urine, do not worry – it usually clears up within a day. Keep drinking water.
• Do not drive if you have had sedation or general anesthesia – arrange for someone to take you home.

Medical treatments

If a cystoscopy shows an infection, your doctor may prescribe antibiotics. If a tumor or abnormal tissue is found, it may be removed during the cystoscopy or with a follow-up procedure called transurethral resection (TURBT). For bladder stones that are too large to remove through the cystoscope, you may need a different procedure like lithotripsy (shattering stones with sound waves) or open surgery. For conditions like interstitial cystitis, treatments can include bladder instillation (putting a solution into the bladder), oral medications, or lifestyle changes. Your doctor will recommend a plan tailored to your specific findings.

When is surgery considered?

Most people do not need open surgery after a cystoscopy. If the cystoscopy reveals a large tumor, a severe stricture (narrowing), or complex bladder stones that cannot be handled through the scope, your doctor may talk to you about more advanced surgical options, such as open bladder surgery or reconstructive procedures. These decisions are made after a full discussion of your condition and overall health.

Living with this condition

After a cystoscopy, you can return to your usual daily activities the next day, unless you were sedated – then you should rest for 24 hours. If the procedure was done for diagnosis only, you may have slight burning when peeing for a day or two. Drinking extra water helps. If you are waiting for biopsy results, it is normal to feel anxious. Your doctor will tell you when to expect the results, usually within a week or two. Follow any aftercare instructions you are given.

Lifestyle tips

• Stay well hydrated – aim for 6-8 glasses of water a day to keep your urinary tract healthy.
• If you smoke, try to quit – smoking is a major risk factor for bladder problems and cancer.
• Avoid holding your urine for long periods – empty your bladder when you feel the urge.
• Practise good bathroom habits – wipe front to back (women) to prevent infections.
• If you have a condition that requires regular cystoscopies (e.g., bladder cancer), attend all follow-up appointments as scheduled.

Diet and exercise

You do not need a special diet after a cystoscopy. However, eating a balanced diet with plenty of fruits, vegetables, and fibre supports overall health. Some people find that reducing coffee, alcohol, and spicy foods helps if they have bladder pain or urgency. Gentle exercise like walking is fine, but avoid heavy lifting for 24-48 hours. Regular physical activity can help with stress and general wellbeing.

Mental health and emotional wellbeing

Waiting for results after a cystoscopy can cause anxiety or worry, especially if a biopsy was taken. It is normal to feel uneasy. If you are diagnosed with a condition like bladder cancer, you may experience shock, sadness, or fear. Remember that many bladder problems are treatable, and early detection often leads to better outcomes. Do not hesitate to talk to your healthcare team about your feelings – they can offer support and connect you with counselling services if needed.

Prevention

While you cannot prevent all conditions that require a cystoscopy, you can lower your risk of bladder problems. The most important step is to avoid smoking – it is the biggest preventable risk factor for bladder cancer. Staying well hydrated, treating urinary tract infections promptly, and reducing exposure to harmful chemicals can also help. For people with an enlarged prostate or recurrent infections, working with your doctor to manage these conditions may reduce the need for cystoscopy.

Screening programmes

Routine screening for bladder problems is not recommended for the general population. If you have risk factors (such as smoking history or family history of bladder cancer), your doctor may suggest regular urine tests or imaging. Cystoscopy is not used as a screening test; it is a diagnostic tool for people who have symptoms or abnormal test results. If you are concerned about your bladder health, speak to your doctor.

Complications

If left untreated

• If a bladder condition is not diagnosed and treated, it may worsen over time. For example, a bladder infection could spread to the kidneys, causing serious illness.
• Undiagnosed bladder stones can cause ongoing pain, bleeding, and blockages.
• Bladder tumors left untreated may grow and spread, making treatment more difficult.
• Chronic urinary symptoms can significantly reduce quality of life, causing discomfort and emotional distress.

Long-term outlook

Cystoscopy is a safe and effective procedure with a very low risk of serious complications. Most people tolerate it well and recover quickly. The procedure provides valuable information that helps doctors make accurate diagnoses and choose the best treatment. If a problem is found, early treatment often leads to good outcomes. Even for conditions like bladder cancer, when caught early, many people are treated successfully and go on to live full lives. Your healthcare team will guide you through every step, from the procedure itself to any follow-up care you may need.
