What should you know about cystoscopy retrograde pyelogram stent placement?

During cystoscopy, the clinician reaches the bladder through the urethra. A small tube is guided into the opening of the ureter, contrast is introduced, and X-ray images show the drainage channel toward the kidney. If drainage is narrowed or obstructed, a soft ureteric stent can be positioned between the kidney and bladder.

A retrograde pyelogram maps the ureter from below, helping the clinician identify the level and shape of a blockage or check the urinary tract when other imaging is insufficient. The contrast travels within the urinary collecting system rather than being injected into a vein.

The stent is an internal drainage tube, not an external urine bag. Its curled ends help keep it in position. It may be used while swelling settles, while a stone or narrowing is treated, or while another cause of obstruction is assessed. It usually requires a specific plan for removal or exchange.

Follow instructions on fasting, medicines, and transport because anaesthesia is commonly involved. Tell the team about allergies, particularly previous contrast reactions, as well as pregnancy, kidney problems, urinary infection symptoms, blood thinners, and implanted devices. Do not stop prescribed treatment without procedure-specific advice.

A stent can cause urinary frequency, urgency, bladder discomfort, flank ache during urination, or some blood-staining. Use the recommended pain relief, fluids, and activity guidance. Before discharge, obtain the stent removal or exchange date and the service to contact; do not assume the stent can remain indefinitely.

Seek prompt medical advice for fever, chills, worsening urinary burning, foul-smelling urine, increasing flank pain, persistent vomiting, or bleeding that is becoming heavier. Urgent assessment is needed if you cannot pass urine, develop severe pain that is not controlled by the advised medicine, pass large clots, feel faint, or become acutely unwell. Report a dislodged visible stent string without pulling it.

Ask what the images showed, why the stent was placed, and whether any biopsy or urine sample was collected. Confirm how long the stent is intended to stay, how removal will happen, what symptoms are expected, and which symptoms require immediate contact. Also ask whether work, exercise, travel, or sexual activity needs temporary adjustment.
