What is Cystoscopy, Why is it Performed and What Happens After the Procedure?

When your doctor tells you "we need to do a cystoscopy", the first questions that come to your mind are probably: Is this procedure painful, how long does it take, is anesthesia required? Cystoscopy is a frequently used diagnostic (and, when necessary, treatment) method in urology practice, which allows direct imaging of the inner surface of the bladder and urethra with a thin camera. In this article, we explain what cystoscopy is, in what cases it is requested, how the procedure goes, and what you should consider normal afterward, in the light of current information.

What is Cystoscopy? Difference Between Flexible and Rigid Cystoscopy

Cystoscopy is the visual examination of the inner surface of the urethra and bladder with the help of a thin instrument (cystoscope) with a camera on its tip. There are two basic types of cystoscopes:

• Flexible cystoscopy: It is performed with a thin and bendable instrument. It is usually applied under outpatient clinic conditions with local anesthesia. It is mostly preferred for diagnostic evaluation purposes and provides an advantage in terms of patient comfort.

• Rigid cystoscopy: It is performed with a larger diameter, inflexible instrument. Due to its image quality and working channel possibilities, it is more frequently preferred for procedural interventions such as biopsy, small tumor treatment or stone/stenosis; it usually requires spinal or general anesthesia.

Which type to choose; it varies depending on whether the procedure is diagnostic or therapeutic, the gender of the patient (the procedure is generally more comfortable in women since the urethra is shorter) and the facilities of the center.

In Which Situations Is Cystoscopy Requested?

Cystoscopy is a valuable diagnostic tool in urinary tract complaints whose cause is unclear. The most frequently requested situations are:

• Blood in the urine (hematuria): Especially in unexplained bleeding, many guidelines recommend cystoscopy as part of the evaluation, depending on the patient's age, smoking history, and risk level.

• Recurrent urinary tract infection: Cystoscopy may be considered if an underlying structural cause (stricture, stone, or foreign body) is suspected. Guidelines recommend considering it in selected patients.

• Bladder tumor diagnosis and follow-up: Cystoscopy is one of the standard methods in the initial diagnosis and post-treatment follow-up of suspected bladder tumor.

• Urination problems and suspicion of urethral stricture: Complaints such as weak urine flow and feeling of obstruction are evaluated together with other tests.

What Does Cystoscopy Reveal About Urethral Stricture?

Cystoscopy is valuable in the evaluation of urethral stricture as it directly shows the location and internal appearance of the stricture; however, it may not be sufficient on its own to determine the exact length and severity of the stenosis, because the camera may not be able to pass beyond the stenotic area. For this reason, the exact map of the stricture is often obtained using cystoscopy and retrograde urethrography (a special x-ray imaging method).

Is the Procedure Painful? Anesthesia Options

The pain level of cystoscopy and the type of anesthesia required cannot be reduced to a single answer; varies depending on these factors:

• Purpose of the procedure: Diagnostic-only flexible cystoscopy is usually completed with local anesthesia, with a slight discomfort. Procedures for therapeutic purposes (such as biopsy, lithotripsy, tumor resection) usually require spinal or general anesthesia.

• Instrument used: Flexible cystoscopy is generally less uncomfortable than rigid cystoscopy.

• Patient characteristics: Pain threshold, anxiety level and previous procedure experiences vary from person to person.

In general, diagnostic flexible cystoscopy is well tolerated by most patients, and a slight feeling of pressure or urinary urgency is described during the procedure; Severe pain is not expected. The procedure generally takes from a few minutes to approximately fifteen minutes; it may take longer when performed for therapeutic purposes.

What Should Be Considered Before and After the Procedure?

Before the procedure, a urinalysis and, if necessary, a urine culture may be requested to evaluate whether there is an active urinary tract infection; In the presence of active infection, the procedure is usually planned after the infection is treated. A slight burning sensation, a stinging sensation and a very small amount of bleeding during the first few urinations after the procedure are common symptoms that usually resolve spontaneously. Drinking plenty of water can help these complaints pass faster.

Is Cystoscopy the Only Diagnostic Method?

No. Cystoscopy is a valuable method that provides a direct view of the inside of the bladder and urethra, but it is not the only tool used in urinary tract evaluation. While ultrasonography evaluates the external appearance and rough structure of the kidney and bladder, computed tomography (CT) and magnetic resonance (MR) image deeper tissues and surrounding organs, and urethrography is used especially to map the length and location of urethral stricture. Which examination is required and when is determined by the urologist according to the patient's complaint and preliminary diagnosis.

When to Consult a Doctor?

Situations requiring urgent evaluation after cystoscopy:

• Symptoms of urinary tract infection accompanied by fever and chills

• Inability to urinate at all after the procedure

• Heavy, clotted or prolonged bleeding

• Severe, gradually increasing lower abdominal pain

Situations that are not urgent but need to be informed: mild burning and small amounts of bleeding lasting more than a few days, persistent cloudiness in the color of the urine — in these cases, a follow-up examination is recommended.

Frequently Asked Questions

How long does cystoscopy take?

Diagnostic flexible cystoscopy is usually completed in a few minutes to fifteen minutes. For therapeutic procedures, the duration may be longer; the exact duration varies depending on the scope of the procedure.

Does cystoscopy require general anesthesia?

Not always. Diagnostic flexible cystoscopy is usually performed with local anesthesia. Spinal or general anesthesia may be preferred for procedural interventions such as biopsy and tumor treatment.

Is a urinalysis required before the procedure?

Generally yes; Urine analysis and culture if necessary are requested to check whether there is an active infection.

Is burning and slight bleeding normal after the procedure?

Yes, mild burning and a small amount of bleeding during the first few urinations are common and usually go away on their own in a short time.

Is cystoscopy different in men and women?

The basic principle is the same, but since the urethra is shorter in women, the procedure usually takes less time and is more comfortable.

Can the exact length of urethral stricture be determined by cystoscopy?

Cystoscopy shows the location and internal view of the stricture, but the exact length usually becomes clear when evaluated in conjunction with imaging methods such as urethrography.

Is cystoscopy required for every recurrent urinary tract infection?

No. Current guidelines recommend that cystoscopy should not be performed routinely in recurrent infections with a typical course, but should be considered in selected patients with alarm findings or an atypical course.

Conclusion

Cystoscopy is a reliable and generally well-tolerated method for clarifying the cause of many urinary tract complaints. The pain level of the procedure and the need for anesthesia vary depending on the person and the purpose of the procedure; Therefore, it is best to get information specific to your situation from your physician who will perform the procedure.
