Preparing for a cystoscopy is straightforward, but the specifics depend on one key detail: whether you’re getting local anesthesia or general anesthesia. Most flexible cystoscopies use a local numbing gel and require almost no advance preparation. Rigid cystoscopies, which often use general or spinal anesthesia, involve fasting and arranging a ride home. Here’s what to do in the days and hours leading up to your procedure.
Know Which Type You’re Having
A flexible cystoscopy uses a thin, bendable scope and typically takes 10 to 15 minutes. You’ll be awake the entire time, with numbing gel applied to your urethra beforehand. A rigid cystoscopy uses a wider, fixed scope and takes around 30 minutes. This type is more common when the doctor needs to take a biopsy or perform a minor treatment, and it usually requires general or spinal anesthesia.
Your preparation checklist changes based on which one you’re getting, so confirm the type and anesthesia plan with your doctor’s office ahead of time.
Eating and Drinking Before the Procedure
If you’re having a local anesthetic, you can eat and drink normally before your appointment. No fasting needed.
If you’re having spinal or general anesthesia, stop eating and drinking at least 8 hours before your scheduled procedure time. That means no food, no water, no coffee. Your doctor’s office will usually tell you a specific cutoff time the night before. An empty stomach reduces the risk of nausea and complications during anesthesia.
Medications: What to Stop and What to Keep
For a routine surveillance cystoscopy with no biopsy planned, most people can continue taking their regular medications, including blood thinners like warfarin. This is one of the few urological procedures where warfarin does not need to be paused beforehand.
The situation changes if a biopsy is expected. When your doctor plans to take a tissue sample during the cystoscopy, blood thinners are typically stopped 3 to 5 days before the procedure to reduce bleeding risk. Your doctor will give you specific instructions based on which blood thinner you take and your personal risk factors. Never stop a blood thinner on your own without being told to.
Continue taking any other daily medications unless your doctor says otherwise. If you take diabetes medication or insulin, ask for specific guidance, since fasting can affect your blood sugar levels.
Antibiotics Before the Procedure
Not everyone needs preventive antibiotics before a cystoscopy. For a simple, diagnostic scope with no biopsy, antibiotics are generally unnecessary as long as your urine culture is clean beforehand. Your doctor may ask you to provide a urine sample at your appointment (or before it) to check for an existing infection.
Antibiotics are more likely to be prescribed if you have risk factors for infection, such as a history of recurrent urinary tract infections, a weakened immune system, or if the procedure involves a biopsy or tissue removal. If your doctor does prescribe an antibiotic, it’s usually a single dose taken before the procedure. Follow the timing instructions closely.
What to Do the Morning Of
Don’t empty your bladder before you leave for your appointment. Your doctor may need a urine sample when you arrive, so showing up with a full (or at least partially full) bladder saves time and avoids the awkward wait to produce one on the spot.
Wear comfortable, loose-fitting clothing. You’ll likely change into a gown, but easy clothes make the process smoother, especially afterward when you may feel some tenderness. Leave jewelry and valuables at home.
Bring a photo ID and your insurance card. If you’re having general or spinal anesthesia, make sure someone is with you who can drive you home. Anesthesia and any pain medication given during the procedure make it unsafe to drive yourself. Even with a local anesthetic, some people feel more comfortable having someone along.
What to Have Ready at Home
Stock up on a few things before your appointment so you’re not scrambling afterward. The most important item is water, and plenty of it. Drinking extra fluids in the hours after a cystoscopy helps flush your bladder and reduces stinging during urination. Juice, water, and even popsicles all count.
For pain relief, over-the-counter options like acetaminophen (Tylenol) or ibuprofen (Advil) are usually enough for the mild burning or soreness that follows a cystoscopy. Having both on hand gives you flexibility, since you can alternate between them every few hours if needed for more consistent relief. Most people find the discomfort manageable and short-lived, typically fading within a day or two.
You may notice a small amount of blood in your urine for the first day after the procedure. This is normal. Light-colored or slightly pink urine is expected and should clear up as you keep drinking fluids.
Managing Anxiety Beforehand
It’s completely normal to feel nervous, especially about a flexible cystoscopy where you’ll be awake. Knowing what to expect helps: the numbing gel takes a minute or two to work, you’ll feel pressure as the scope passes through but not sharp pain, and the whole thing is over in about 10 to 15 minutes. Some people describe it as uncomfortable but tolerable.
If anxiety is a real concern for you, mention it to your doctor beforehand. Some offices offer a mild sedative for patients who are particularly anxious, even during a local-anesthetic procedure. Deep, slow breathing during the cystoscopy itself also helps relax the pelvic floor muscles and makes the scope easier to pass.
