What is a flexible cystoscopy ?
Flexible cystoscopy is a quick procedure where an urology clinician uses a thin, flexible camera (cystoscope) to look inside the urethra (urine channel) and bladder. It is commonly done in the office/outpatient clinic with numbing gel and usually does not require general anesthesia.
Why it may be recommended.
Flexible cystoscopy helps your clinician look for causes of urinary symptoms and check the bladder lining. Common reasons include:
- Blood in the urine (haematuria)—cystoscopy is a key test to check for bladder tumours and other causes.
- Recurrent urinary tract infections (UTIs) or concern for a bladder/urethral problem.
- Bladder cancer check-ups (surveillance) if you have had bladder cancer before.
What happens during the procedure (typical).
You will lie on an exam table.
The area is cleaned, and numbing gel (local anesthetic) is placed into the urethra.
The flexible scope is gently passed into the bladder.
Sterile fluid is used to fill the bladder so the clinician can see well.
The procedure usually takes only a few minutes.
What it feels like.
Most people tolerate flexible cystoscopy well.
In a prospective study of 420 patients, the median pain score was 1.1 out of 10, and 1.8% reported pain >5/10. 1
You may feel:
Pressure or a brief burning feeling when the scope passes
A strong urge to urinate when the bladder is filled
After the procedure: what is normal.
It is common to have temporary symptoms, especially during the first day or two:
Burning with urination
Frequent urination
Small amounts of blood in the urine
In one prospective study of 420 patients, at about 7 days:
Burning/pain with urination occurred in 50%
Urinary frequency in 37%
Visible blood in urine in 19% These symptoms are usually short-lived.
Infection risk (UTI) and antibiotics.
A UTI can happen after cystoscopy, but serious infection is uncommon.
In a prospective study of 1,091 flexible cystoscopies, a broadly defined post-procedure UTI rate was 13.3%, and no one developed urosepsis.
In another prospective study using a stricter definition, flexible-cystoscopy–related infection was 2.7% (110-patient subset with urine testing).
Antibiotics:
For simple outpatient diagnostic cystoscopy in healthy adults without UTI symptoms, routine preventive antibiotics are not recommended.
A randomized trial in low-risk patients (265 completed) found UTI symptoms at 7 days in 3.85% with antibiotics vs 5.93% without antibiotics (no important difference).
If you have higher infection risk (for example, certain bladder/kidney conditions or immune problems), your clinician may recommend antibiotics—follow their plan.
Urine testing and “positive dipstick”.
Sometimes a urine dipstick on the day suggests infection even when you feel fine.
In a prospective study of 1,996 patients, 6.8% developed a post-cystoscopy UTI by the study’s definition, and no patient developed urinary sepsis, even when the dipstick suggested infection but the person had no symptoms.
How to care for yourself at home.
Drink extra water for the rest of the day (unless your clinician told you to limit fluids).
You can usually return to normal activities the same day.
If you have burning, ask your clinician what pain relief is safe for you.
When to seek urgent medical advice.
Get urgent help if you have:
Fever or chills
Worsening pain or severe lower belly pain
Cannot urinate
Heavy bleeding (large clots, or urine that stays very red)
Feeling very unwell, dizzy, or weak
Special note for some neurologic conditions
If you have a spinal cord injury or another condition that puts you at risk for autonomic dysreflexia (a sudden dangerous rise in blood pressure), tell the team before the procedure so you can be monitored closely.
