What should you know about cystoscopy and retrograde?

The clinician guides a cystoscope through the urethra into the bladder. A small amount of contrast is then introduced through the openings of one or both ureters, the tubes carrying urine from the kidneys. X-ray images show the shape and passage of the ureters and kidney drainage system. This can help investigate a narrowing, blockage, bleeding source or an unusual imaging result.

The study is not the same as a routine cystoscopy because it adds contrast imaging above the bladder. If a suspicious bladder area is seen, the team may discuss sampling or another procedure. A finding may have several possible explanations, so results are interpreted with your symptoms and other tests.

Tell the team about contrast reactions, kidney problems, pregnancy, infection symptoms and medicines that affect bleeding. Follow instructions about fasting and transport. After the examination, temporary burning, urgency or light blood in the urine may occur. Drink according to your discharge advice and avoid strenuous activity until the team says it is appropriate.

Call the treating service promptly for fever, chills, worsening side or back pain, persistent vomiting, heavy bleeding, clots or inability to urinate. These symptoms can indicate infection, obstruction or bleeding that needs assessment.

Ask which part of the urinary tract needs clarification, whether contrast is planned, how allergies or kidney function affect preparation, whether a stent could be needed, and when the images will be reviewed with you.
