Cystoscopy with a left retrograde pyelogram

The word “left” identifies the urinary tract side being studied. “Retrograde” means contrast is introduced upward from the bladder into the ureter rather than given into a vein. X-ray images then outline the channel through which urine drains from the left kidney.

A clinician passes a cystoscope through the urethra to view the bladder and locate the left ureteric opening. A fine catheter is guided into that opening, contrast is introduced, and imaging records the outline of the ureter and collecting system. The images can reveal the position of a narrowing, blockage or filling abnormality without assuming what caused it.

Depending on the reason for the procedure, the team may also collect a sample, place a temporary ureteric stent or plan a separate treatment. Ask whether any additional step is intended because it can change the anaesthetic, recovery and follow-up.

Follow the hospital’s fasting instructions and provide a current list of medicines, allergies and previous reactions to contrast or anaesthesia. Mention pregnancy or possible pregnancy before imaging. Only adjust anticoagulants or diabetes medicines according to an individual plan from the treating team.

After discharge, take medicines exactly as prescribed and follow any fluid guidance. Temporary urinary burning, urgency, mild bladder discomfort or lightly blood-stained urine may occur. If a stent was placed, you may also notice flank discomfort or urinary frequency; the team should tell you how and when it will be removed or reviewed.

Contact the urology service if pain escalates, urinary bleeding becomes heavier, clots develop, vomiting prevents fluids, or urinary symptoms persist beyond the expected recovery described at discharge. Report new flank pain, particularly if a stent is present.

Go for urgent assessment if you cannot urinate, have fever with shaking chills, develop severe pain in the side or lower abdomen, faint, or experience breathing difficulty or facial swelling. These symptoms warrant timely evaluation after urinary instrumentation or medication exposure.

Ask what the clinician is looking for on the left side, which anaesthetic is planned, whether biopsy or stent placement is possible, and when results will be discussed. Confirm who will remove a stent, if used, and which number to call outside clinic hours.
