Cystoscopy for Bladder Cancer
Cystoscopy is the most direct way to examine the inside of the bladder. A thin flexible or rigid telescope is passed through the urethra so the urologist can inspect the bladder lining for tumours, carcinoma in situ, stones, inflammation and other abnormalities. Flexible cystoscopy is commonly performed in an outpatient setting with local anaesthetic gel and usually takes only a few minutes. If a tumour is seen, cystoscopy does not usually provide full treatment on the spot; a transurethral resection of bladder tumour (TURBT) is then arranged under anaesthesia to remove the lesion and obtain proper pathology.
Why is cystoscopy needed?
- Visible or persistent unexplained haematuria.
- Suspicious finding on ultrasound or CT.
- Follow-up after previous non-muscle-invasive bladder cancer.
- Persistent urinary symptoms when carcinoma in situ or another bladder lesion is a concern.
- Assessment before or after selected bladder procedures.
Flexible vs rigid cystoscopy
| Feature | Flexible cystoscopy | Rigid cystoscopy |
|---|---|---|
| Setting | Usually outpatient / clinic procedure | Usually operating theatre or procedure room |
| Anaesthesia | Local anaesthetic gel in most patients | Often spinal or general anaesthesia |
| Purpose | Diagnosis and surveillance | Biopsy, tumour resection and other interventions |
| Instrument | Thin, bendable scope | Straight metal scope with larger working channel |
How should you prepare?
Most flexible cystoscopies require little preparation. You can usually eat and drink normally unless told otherwise. Tell the team about urinary infection symptoms, blood thinners, pregnancy possibility where relevant, allergies and recent procedures. Some centres check a urine sample before the test.
What happens during flexible cystoscopy?
- You lie on the examination couch and the genital area is cleaned.
- Local anaesthetic/lubricating gel is placed in the urethra.
- The flexible cystoscope is passed gently into the bladder.
- Sterile fluid is used to fill the bladder so the lining can be inspected.
- The scope is withdrawn after the bladder and urethra are assessed.
You may feel pressure, urgency or brief stinging. The procedure is generally uncomfortable rather than severely painful.
What can cystoscopy find?
- Papillary bladder tumours.
- Flat red or velvety areas suspicious for carcinoma in situ, although these can be subtle.
- Bladder stones.
- Inflammation, bleeding sites or foreign material.
- Urethral narrowing or prostate-related obstruction.
What happens if a tumour is seen?
The next step is usually TURBT. This removes visible tumour and samples the bladder wall so the pathologist can determine grade and whether muscle is invaded. A small office biopsy may occasionally be used for selected lesions, but it does not replace adequate TURBT when staging is required.
After the procedure
Mild burning, frequency and a small amount of blood in the urine for a day or two can occur. Drinking normally and passing urine regularly is usually sufficient. Follow any specific advice if you have kidney or heart conditions that limit fluid intake.
When to seek medical help
- Fever, chills or feeling systemically unwell.
- Inability to pass urine.
- Heavy bleeding or persistent clots.
- Severe worsening pain.
What a normal cystoscopy does not assess
Cystoscopy gives an excellent direct view of the urethra and bladder lining, but it does not directly inspect the kidneys or most of the ureters. If haematuria evaluation requires upper-tract assessment, imaging is still important even when cystoscopy is normal. Urine cytology can add information in selected patients, particularly when high-grade urothelial cancer or carcinoma in situ is suspected.
A flat carcinoma in situ can also be subtle. When cystoscopy, cytology and symptoms do not fit together, enhanced cystoscopy, directed biopsies or further upper-tract evaluation may be considered depending on the clinical setting.
Consultation checklist
- Reason for cystoscopy and previous haematuria history.
- Urine test/culture if available.
- Previous cystoscopy or TURBT reports.
- CT/ultrasound findings.
- Blood thinners and drug allergies.
- Previous urinary infection or difficult catheterisation history.
FAQs
Is cystoscopy painful?
Flexible cystoscopy usually causes brief stinging, pressure and urgency rather than severe pain. Local anaesthetic gel is used.
Can cystoscopy miss bladder cancer?
Small or flat lesions such as carcinoma in situ can be subtle. Cytology, enhanced cystoscopy techniques and biopsies are used in selected high-risk situations.
Does cystoscopy need anaesthesia?
Flexible diagnostic cystoscopy usually needs only local gel. Rigid cystoscopy and TURBT are commonly performed under spinal or general anaesthesia.
Can I drive after flexible cystoscopy?
Usually yes if only local anaesthetic gel was used and you feel well, but follow the centre’s instructions. Sedation or general anaesthesia changes driving restrictions.
Why do bladder-cancer patients need repeated cystoscopy?
NMIBC frequently recurs, and cystoscopy can detect new tumours while they are still small and treatable.
