A cystoscopy with retrograde pyelogram is a same-day urology procedure that lets a doctor look inside the bladder and take detailed X-ray images of the ureters and kidneys using contrast dye.
Unexplained blood in the urine, a suspicious narrowing, blockage, or filling defect seen on a CT or ultrasound, recurrent one-sided flank pain or infections, or the need to place, check, or remove a ureteral stent.
Bleeding, infection, and rarely injury to the ureter, bladder, or urethra. Risks are minimised by careful patient selection, pre-procedure urine testing, and experienced urology teams.
Standard blood work, a urine test to rule out infection, review of medications (especially blood thinners), an anaesthesia consultation, and fasting per protocol.
A same-day check before discharge, a follow-up visit if a ureteral stent was placed (for removal or exchange), and a plan for the findings β whether that means stone treatment, monitoring a stricture, or another imaging study.
Think of it as two tests done together, through one small camera:
Doctors reach for this test when they specifically need to see the ureter’s inner lining and course β for example, to confirm a stone, a stricture (narrowing), a blood clot, or a suspicious area before biopsy, or to place or check a ureteral stent. It’s also useful for people who can’t have contrast dye injected into a vein, because the amount absorbed into the bloodstream this way is very small. It can also confirm the position of a ureteral stent or catheter placed for a blockage in the urinary system.
A few patterns tend to bring people to this test. None of them mean you definitely need it β your urologist will decide based on your scans and symptoms β but theyβre common reasons it comes up in a work-up.

If you’ve noticed blood in your urine, ongoing flank or back pain, or a scan that mentioned a blockage or narrowing you don’t fully understand, it’s worth getting it checked β most causes turn out to be manageable once they’re identified, and a simple blood or urine test is often the first step your doctor will suggest. You don’t need to have all the answers before reaching out. Find a urologist to talk through your symptoms and work out whether this test, or something else, is the right next step for you.
This test offers a level of detail that other imaging sometimes can’t match, and it can combine diagnosis with a first step of treatment in the same visit.
The treatment has risks and trade-offs to discuss with your care team. The information below comes from this treatmentβs data. Bleeding, infection, and vascular access or instrumentation issues are the main concerns; risks are minimised by careful patient selection and experienced teams.
Who it may not suit: These are general cautions, not a personal verdict. A qualified clinician must assess your full medical picture before recommending or delaying treatment β this includes anyone with a current urinary tract infection, a bleeding disorder or blood-thinning medication, or a known allergy to contrast dye, iodine, or anesthesia medications.
Β
Most people recover without incident. When complications happen, they’re usually manageable and caught early, and your team will tell you exactly which warning signs apply to your case before you go home.
New or severe symptoms require prompt medical advice. Do not wait for a routine appointment if you feel seriously unwell.

When to call your care team:
Getting back to normal: Most people return to normal daily activities within a day or two. If a stent was placed, keep the follow-up appointment for its removal or exchange β stents aren’t meant to stay in indefinitely. Ask your urologist what the test found and what it means for your next steps, whether that’s stone treatment, monitoring a stricture, or another follow-up scan.

No. A CT urogram uses dye injected into a vein and a CT scanner; a retrograde pyelogram injects dye directly into the ureter through a cystoscope and uses plain X-ray (fluoroscopy). It gives a very detailed picture of the ureter's inner lining and is often used when CT findings need confirming, or when IV contrast isn't an option.
Often yes. Only a small amount of the dye is absorbed by the body during a retrograde pyelogram, so it can typically still be performed even with a contrast allergy or reduced kidney function β but always tell your team about any allergy beforehand so they can plan accordingly.
Usually not fully β general, spinal, or deep sedation anesthesia is standard, so most people don't feel the procedure itself.
Sometimes. If the retrograde pyelogram confirms a blockage β from a stone, stricture, or swelling β your urologist may place a temporary ureteral stent in the same session to protect kidney drainage until the underlying cause is treated.
A small amount for a day or two is expected. Heavy bleeding, or bleeding that doesn't improve, is not β contact your care team.
Many people return to light activity within 1β2 days, depending on the anesthesia used and whether a stent was placed. Ask your team for guidance specific to your job and your case.
