Although white light imaging (WLI) cystoscopy has long been considered the gold standard in the diagnosis of bladder cancer, it can miss lesions in a substantial percentage of patients and is very likely to miss carcinoma in situ and dysplasia. Tumor margin detection by WLI can be inaccurate.
How is cystoscopy used to treat bladder cancer?
· For instance, traditional white light cystoscopy has a limited ability to detect certain types of bladder cancer such as small papillary tumors (a type of cancer that grows out towards the hollow center of the bladder in small finger-like projections) and carcinoma in situ (a flat, high-grade type of non-muscle-invasive bladder cancer that carries a risk of metastasis).

· May 24, 2021. Jason M. Broderick. Cystoscopy showed alarming limitations, including failure to detect residual muscle invasive bladder cancer (MIBC) in one-fourth of patients at the time of radical cystectomy, according to findings from a prospective study published in the Journal of Urology. 1,2.
How is cystoscopy used to take biopsy samples?
Cystoscopy can be used to take biopsy samples from the bladder or urethra (to find out if an abnormal area is cancer, for example). This is done by passing long, thin instruments down the cystoscope, such as small forceps (tweezers) to collect the samples. The biopsy samples are then looked at in the lab. You have a bladder problem that needs treating (including some early …
Can bladder cancer be missed?
In many bladder cancer cases, a delayed diagnosis of a few months or even weeks can be the difference between a treatable condition and a devastating, if not fatal, outcome.
Does cystoscopy always show bladder cancer?
Some doctors find these urine tests useful in looking for bladder cancers, but they may not help in all cases. Most doctors feel that cystoscopy is still the best way to find bladder cancer.
How accurate is a cystoscopy?
Table 9 shows that urine makers and cystoscopy have the same highest sensitivity and the highest specificity of 97.2% and 97%, respectively. The table also shows that of the combined methods, the highest sensitivity of 94% and the highest specificity of 90% are found in urine markers and urine cytology.
Can a CT scan Miss bladder cancer?
Can a CT scan miss bladder cancer? CT scans can provide important information about the urinary tract and bladder tumors. However, while some bladder tumors may be seen on a CT scan, others may not be apparent, such as smaller or flatter tumors.
How accurate is urine cytology?
Urine cytology is associated with a significant false-negative rate, especially for low-grade carcinoma (10-50% accuracy rate). The false-positive rate is 1-12%, although cytology has a 95% accuracy rate for diagnosing high-grade carcinoma and CIS. Urine cytology is often the test used for diagnosis of CIS.
What cystoscopy can detect?
Cystoscopy is a procedure that lets the healthcare provider view the urinary tract, particularly the bladder, the urethra, and the openings to the ureters. Cystoscopy can help find problems with the urinary tract. This may include early signs of cancer, infection, narrowing, blockage, or bleeding.
Is cystoscopy better than ultrasound?
While the tolerability of cystoscopy is relatively low, it is still superior to ultrasonography in the evaluation of the bladder as a possible source of hematuria. Painless hematuria usually is the sole presenting symptom in the majority of patients with bladder cancer.
Is there an alternative to a cystoscopy?
There are no real alternatives to cystoscopy. Imaging studies such as ultrasound or CT can miss small lesions such as tumours. For this reason, a cystoscopy is recommended for anyone who has bladder symptoms such as bleeding.
Can a biopsy be done during a cystoscopy?
Cystoscopy can be used to take biopsy samples from the bladder or urethra (to find out if an abnormal area is cancer, for example). This is done by passing long, thin instruments down the cystoscope, such as small forceps (tweezers) to collect the samples. The biopsy samples are then looked at in the lab.
Does bladder cancer always show up on CT scan?
While some bladder tumors may be found on a CT urogram or other imaging test, others will not. A urologist will often recommend a cystoscopy to evaluate the lower urinary tract (bladder/urethra) for a source of blood in the urine or to workup other urologic symptoms.
Can bladder cancer symptoms come and go?
Symptoms often come and go, and are often not severe. The most common symptoms include the following: Hematuria (blood in the urine) — The most common sign of bladder cancer is blood in the urine (hematuria).
How accurate is a CT scan in detecting bladder cancer?
Computed tomography (CT) It has a reported sensitivity of 85% and specificity of 94% for the diagnosis of bladder cancers [11]. Detection is dependent on the morphology and size of the tumor.
Detecting Bladder Cancer with a Cystoscopy
Cystoscopy enables the inside of the urethra and bladder to be examined and sampled. Alongside urine testing and diagnostic imaging procedures, cystoscopy is used in both the initial diagnosis of bladder cancer and in ongoing surveillance for recurrence.
What is a cystoscopy?
A cystoscope is a thin tube with a light and camera attached to the end. During a cystoscopy, the cystoscope is passed through the urethra (the tube through which urine leaves the bladder) into the bladder. The two main types of cystoscopy are termed flexible and rigid:
Preparing for a cystoscopy
The process of preparing for a cystoscopy depends on which type of cystoscopy and anaesthetic a patient is undergoing. For example:
What happens during a cystoscopy?
During flexible cystoscopy, the patient lies on their back and an anaesthetic gel is passed into the urethra to make the area numb. Once the local anaesthetic is working, the doctor inserts the cystoscope through the urethra and then into the bladder.
What to expect after a cystoscopy
Patients usually leave the hospital on the same day of a cystoscopy. Depending on the type of anaesthesia used, it may be necessary to arrange a ride home with a friend or family member.
Are there any risks associated with cystoscopy?
Cystoscopy is usually a safe procedure and serious complications are uncommon. The most frequent complication is urinary tract infection (UTI).
Cystoscopy results
Depending on the type of cystoscopy procedure undertaken, results may be communicated to the patient immediately or at a follow-up appointment. These may include images taken during the procedure and the results of laboratory tests carried out on any tissue samples collected.
Does cystoscopy detect MIBC?
Cystoscopy showed alarming limitations, including failure to detect residual muscle invasive bladder cancer (MIBC) in one-fourth of patients at the time of radical cystectomy, according to findings from a prospective study published in the Journal of Urology. 1,2
What should future work focus on?
The authors wrote in the conclusion of their paper that, “Future work should focus on novel imaging and biomarker strategies to optimize evaluations before radical cystectomy for improved decision making regarding bladder preservation.”.
What is a cystoscopy?
What is cystoscopy? Cystoscopy is a procedure a doctor uses to look at the inside of the bladder and urethra ( the tube that connects the bladder to the outside of the body). This is done with a cystoscope, a thin tube with a light and a lens or small video camera on the end. The tube is put in through your urethra.

Having a cystoscopy with local anesthetic
A cystoscopy is performed in a urologist’s office with a local anesthetic. There really is no preparation. Upon arrival, I was asked to give a urine sample. I do this at every visit to ensure there is no infection. Then I’m led into the procedure room.
Stress affected my pain levels
The doctor came in and inserted the cystoscopy tube. I have had several and I can honestly say, some were simply uncomfortable and some were downright painful. I suspect, and this my own opinion, my stress level probably led to the difference in how I felt upon insertion.
Seeing my bladder on the screen
Look up at the monitor. You will immediately see your bladder. We could see the smooth lining, we could see urine coming from my kidneys through my ureters, and then finally, we found the tumor. (This is when I pulled out my cell phone and took a picture of the monitor screen – a difficult task while laying down with legs up in the air).
Needing a biopsy to confirm a diagnosis
At this point, my urologist told me that although he wouldn’t be sure until he took a biopsy, it looked cancerous to him. My feeling is, they must tell you they won’t know until they receive the biopsy results, but they’ve been doing it long enough they can generally tell by its appearance.
Slight soreness that went away quickly
He said goodbye and that was it. It was a fairly simple procedure but of course, the thought of something being inserted where things should only come out still makes me a nervous wreck. I had a little soreness walking out of the office but by the time I got home, I was absolutely fine.
