How Is a Cystoscopy Performed on a Female?

A cystoscopy in a female is performed by inserting a thin, lighted scope through the urethra and into the bladder, typically in an office or outpatient setting with only local numbing gel for anesthesia. Because the female urethra is short, the procedure is quicker and generally less uncomfortable than in men, often taking just a few minutes from start to finish. The simplicity of the setup, though, masks a surprising amount of variation in technique, equipment choice, and pain management that can meaningfully change a patient’s experience.

Why a Cystoscopy Might Be Ordered

The most common reasons a woman is referred for cystoscopy include blood in the urine (hematuria), recurrent urinary tract infections, bladder pain, urinary incontinence, and surveillance after bladder cancer treatment. For recurrent UTIs in particular, the procedure lets the urologist look directly at the bladder lining and urethra for abnormalities that imaging alone might miss.¹ Some women are also scoped to investigate persistent overactive bladder symptoms, suspected bladder stones, or to check for conditions like interstitial cystitis.

During pelvic reconstructive surgery for organ prolapse, cystoscopy plays a different role entirely. The American Urogynecologic Society recommends universal cystoscopy at the time of nearly all pelvic reconstructive surgeries to check for accidental injury to the bladder or ureters during the operation.² Catching a surgical nick or a kinked ureter while the patient is still in the operating room can prevent far more serious complications later.

Preparing for the Procedure

Preparation is minimal compared to many medical procedures. You do not need to fast or stop eating beforehand. Most offices will ask you to provide a urine sample before the cystoscopy so they can check for an active infection. If you have an untreated urinary tract infection, the procedure is typically postponed until the infection clears, because scoping an actively infected bladder raises the risk of spreading bacteria and making things worse.³

One thing that has changed in recent years is the approach to preventive antibiotics. Doctors used to routinely prescribe a dose of antibiotics before cystoscopy, but the evidence increasingly shows this is unnecessary for most women. A study of bladder tumor patients found that skipping prophylactic antibiotics did not lead to more infections, and current thinking favors antibiotic stewardship over blanket prescriptions.⁴ A quality-improvement study in women found no meaningful change in UTI rates after cystoscopy when routine prophylactic antibiotics were dropped, but antibiotic-related side effects fell sharply, from about 8.5% of patients down to 1.5%.⁵ There are still specific situations where your doctor may prescribe a preventive dose, such as if you have a history of recurrent infections or certain implanted medical devices, but for the average patient it is no longer standard.

Flexible Versus Rigid Scopes

Two types of cystoscopes exist: flexible and rigid. Both are slender tubes fitted with a camera and a light source, but they differ in construction and how they feel going in. A flexible cystoscope bends at the tip, allowing the operator to steer it through the urethra more gently. A rigid cystoscope is a straight metal tube that offers a wider, brighter view and has larger working channels for passing instruments. In men, flexible scopes are strongly preferred because the male urethra is long and curved, making rigid insertion significantly more painful. In women, the urethra is only about 4 centimeters long, so the difference in comfort between the two types is less dramatic.

The research on which scope hurts less in women is genuinely mixed. One study found that median pain scores were significantly lower with flexible cystoscopy compared to rigid, and that the benefit remained even after adjusting for age and other variables.⁶ But other trials found no meaningful difference. A randomized trial directly comparing flexible and rigid cystoscopy in women reported median pain scores of 0.9 versus 0.5 on a 10-point scale, a gap that was not statistically significant.⁷ Another study similarly found no significant difference in discomfort during the procedure or in recalled pain a week later.⁸

What this means practically is that many urologists choose the scope type based on what they need to do rather than purely on comfort. Rigid scopes are often preferred when a biopsy, stone removal, or cauterization is planned, because they allow larger instruments to pass through. Flexible scopes are the default for straightforward diagnostic looks. If you have a strong preference, it is worth asking your urologist ahead of time, but for most women the difference in pain is modest either way.

What Happens During the Procedure Step by Step

You will be asked to undress from the waist down, lie on your back on an exam table, and bend your knees with your feet in stirrups, similar to a gynecological exam position. The area around your urethral opening is cleaned with an antiseptic solution.

Next comes the anesthetic. For office-based cystoscopy, this is almost always a gel containing lidocaine that is gently squeezed into the urethra. The gel both numbs the tissue and lubricates the passage for the scope. A randomized trial found that women who received 2% lidocaine gel reported meaningfully lower pain scores during the procedure compared to women who received plain lubricant without anesthetic, with average pain ratings dropping from about 3.6 to 2.4 on a 10-point scale.⁹ The gel needs a minute or two to take effect. Some practices allow a longer dwell time for the lidocaine, though opinions vary on whether extra waiting time adds much additional numbing.

The urologist then gently guides the scope through the urethra and into the bladder. Because the female urethra is short, this part takes only seconds. Once the scope is inside the bladder, sterile water or saline is slowly infused through the scope to expand the bladder walls. This filling is what allows the doctor to see the entire inner surface. You will feel a sensation of bladder fullness, and some women describe it as the strongest part of the discomfort. The doctor methodically inspects the bladder lining, looking for redness, lesions, tumors, stones, or structural abnormalities. The ureteral openings, where urine enters the bladder from the kidneys, are also checked to confirm that both are functioning. The entire inspection typically takes three to five minutes. When finished, the scope is withdrawn, the bladder drains, and you can usually get dressed and leave within a few minutes.

Managing Pain and Anxiety

Most women rate the discomfort as mild, somewhere in the range of 1 to 3 on a 10-point scale with lidocaine gel. That said, anxiety before the procedure often outweighs the actual physical sensation. First-timers tend to report higher pain scores than women who have been through it before, partly because not knowing what to expect amplifies the unpleasantness.

One surprisingly effective and low-cost intervention is music. A systematic review of studies on music during flexible cystoscopy found that three out of four trials showed significantly reduced pain and anxiety when patients listened to music of their choosing during the procedure.¹⁰ The review concluded that music should be routinely offered, especially for patients who need repeated cystoscopies for surveillance. If your clinic does not offer headphones, bringing your own earbuds and a playlist is a simple way to take the edge off.

Age also appears to influence the experience. Research has found that younger women tend to report more pain than older women, with a statistically significant inverse relationship between age and pain scores.⁶ The reasons are not entirely clear. It may be related to differences in anxiety levels, urethral tissue characteristics, or simply familiarity with medical procedures. Regardless, younger women and first-timers may want to be especially proactive about requesting lidocaine gel and considering distraction techniques.

What Cystoscopy Can Find

The range of findings is broad. In addition to tumors and stones, the bladder lining itself tells a story. For women being evaluated for interstitial cystitis or bladder pain syndrome, the doctor may perform a hydrodistention, filling the bladder under anesthesia to look for characteristic patterns of tiny hemorrhages called glomerulations or for Hunner’s lesions, which are inflamed, ulcer-like patches. The presence of Hunner’s lesions specifically defines interstitial cystitis and distinguishes it from broader bladder pain syndrome, which matters because the two conditions are managed differently.¹¹

For women with recurrent UTIs that do not respond to standard antibiotic courses, cystoscopy sometimes reveals inflammatory bladder lesions. These can be treated during the procedure itself through electrofulguration, a technique where a small electric current is used to cauterize the inflamed tissue. A study of women with antibiotic-resistant recurrent UTIs who underwent office electrofulguration found that most patients improved, with 15 out of 57 cured and 37 improved over a mean follow-up of roughly three years.¹² Follow-up cystoscopy is then performed about six months later to assess healing.¹³ This blurs the line between diagnostic and therapeutic, and it is one of the reasons cystoscopy remains valuable even as imaging technology improves.

Risks and What to Expect Afterward

Cystoscopy is a low-risk procedure. The most common side effect is mild burning or stinging when you urinate for the first day or two afterward. A small amount of blood in the urine is normal and usually clears within 24 to 48 hours. Drinking extra water after the procedure helps flush the bladder and reduces that stinging.

The main concern most women have is whether the procedure will cause a urinary tract infection. The risk is real but modest. A large study of over 3,100 cystoscopies found that a fever-causing UTI developed within 30 days in about 1.9% of patients. The rate was higher in those who already had bacteria in their urine before the procedure (about 3.7%) compared to those with sterile urine (about 1.4%), but all infections resolved with oral antibiotics within a day or two, and no patient needed hospitalization.¹⁴ These are reassuring numbers, and they help explain why the trend away from routine prophylactic antibiotics has gained so much momentum.

You should contact your doctor if you develop a fever, notice heavy bleeding that does not clear, or experience pain that worsens rather than improves over the first couple of days. These symptoms are uncommon but warrant prompt evaluation.

Cystoscopy During Pelvic Reconstructive Surgery

A cystoscopy performed during an operation for pelvic organ prolapse or incontinence looks somewhat different from the office version. The patient is already under anesthesia, so pain is not a concern. The urologist or urogynecologist inserts a rigid scope and fills the bladder to inspect for any accidental injury caused by the surgery, such as a suture passing through the bladder wall or a ureter that has been kinked or blocked by the repair. Indigo carmine dye or another marker is sometimes injected intravenously so that the doctor can watch for colored jets of urine from each ureter, confirming that both kidneys are draining freely.

The consensus recommendation is that this intraoperative cystoscopy should be performed after virtually all pelvic reconstructive surgeries, with the only exception being operations that address only the back wall of the vagina, where the risk to the bladder and ureters is minimal.² Detecting an injury in the operating room means it can be repaired immediately, avoiding the pain and additional surgeries that come from finding it days later.

Blue-Light Cystoscopy and Newer Technology

Standard cystoscopy uses white light, and it has been the workhorse of bladder inspection for over a century. But white light has blind spots. Flat, early-stage bladder tumors and carcinoma in situ can look nearly identical to normal tissue under white illumination. Blue-light cystoscopy addresses this by having the patient receive a photosensitizing agent, typically instilled directly into the bladder beforehand. Tumor cells absorb the agent preferentially and fluoresce pink or red under blue light, making them stand out dramatically.

The improvement in detection is substantial. A meta-analysis comparing the two approaches across 11 studies found that blue-light cystoscopy detected bladder cancer with about 93% sensitivity, compared to about 73% for standard white-light cystoscopy.¹⁵ That 20-percentage-point gap translates into meaningfully fewer missed tumors. Blue-light cystoscopy is most commonly used during bladder cancer surveillance and during tumor resection procedures, rather than for first-time diagnostic cystoscopies in women being evaluated for UTIs or incontinence. However, its availability is growing, and if you are being monitored for a history of bladder cancer, it is worth asking whether your facility offers it.

Cystoscopy in Children

When cystoscopy is needed in girls or adolescents, the procedure requires significant modifications. Children are less cooperative, more anxious, and their anatomy is smaller, so sedation or general anesthesia is used far more often than in adults. Smaller-diameter scopes are necessary, and the technique for bladder filling has to account for smaller bladder capacities. The indications are also different from adults, as children are more commonly scoped for congenital abnormalities, vesicoureteral reflux, or recurrent infections that do not respond to treatment, rather than for tumor surveillance or incontinence.

How the Cystoscope Evolved

The basic idea of looking inside the bladder through a tube has been around for over two centuries. The earliest recognizable prototype was an 1805 urethral viewing tube that used reflected candlelight for illumination. The images were inverted and backwards, objects appeared tiny and far away, and the experience was uncomfortable at best and dangerous at worst for both patient and operator.¹⁶ The introduction of lenses, prisms, and eventually the incandescent light bulb transformed the cystoscope into something genuinely useful. By the late 1800s, the instrument was good enough that doctors could not only see inside the bladder but also pass small tools through it, expanding urology from a field focused primarily on venereal disease into a full surgical specialty. The invention of fiber optics in the twentieth century and, later, digital camera chips brought image quality to the level that modern urologists enjoy: high-definition video that can be displayed on a monitor, recorded, and shared with the patient in real time. That last point matters more than it might sound. Being able to watch the screen during your own cystoscopy can be surprisingly reassuring, and many urologists will walk you through what they are seeing as they go.
