Patient FAQs
Clear answers about the dtb-instiller™ intermittent and your treatment
When should I seek help after dtb-instiller™ treatment?
Contact your treating team or NHS 111 promptly if you develop fever, shivering, worsening pain or bleeding after treatment.

Benefits for Patients
Understanding how dtb-instiller can help you
What is the dtb-instiller™ intermittent?
The dtb-instiller™ intermittent is a thin, flexible catheter used to drain urine from your bladder and then deliver prescribed medicine directly into it. This is called intravesical treatment. The device has two separate channels: one for urine drainage and one for the medicine. Your healthcare team will explain why it has been recommended for you.

Before Your Appointment
• Drink plenty of water to stay hydrated
• Wear comfortable, loose-fitting clothing
• Bring a list of any medications you're currently taking
• Arrange transportation if advised by your healthcare team
Targeted Treatment
Medication goes directly where it's needed
What happens during treatment with the dtb-instiller™?
The device follows a “Drain. Close. Instil.” sequence. First, urine is drained from the bladder. The drainage openings are then closed using the device’s slider and sleeve, before the prescribed medicine is delivered through its separate channel. Your healthcare team will explain each stage and use the device in line with its Instructions for Use.
When to Contact Your Healthcare Team
While side effects are usually mild, contact your doctor if you experience:
• Severe pain or discomfort
• Heavy bleeding or blood clots in urine
• Fever or chills
• Inability to urinate
• Symptoms that worsen or don't improve after 48 hours
Day of Procedure
• Arrive at the scheduled time
• You may be asked to empty your bladder before the procedure
• The procedure room will be clean and comfortable
• Your healthcare team will explain each step
Fewer Side Effects
Reduced impact on the rest of your body
Which medicine will I receive through the dtb-instiller™?
Your clinician chooses the medicine based on your condition and treatment plan. The dtb-instiller™ is the device used to deliver that medicine; it is not a medicine itself. Ask your team what you are receiving, the expected benefits and risks, how long it needs to stay in your bladder, and how many treatments are planned.
Can the dtb-instiller™ intermittent be reused?
No. The dtb-instiller™ intermittent is a single-use device. A new device is needed for each procedure, even if it is for the same person. Do not wash or reuse it. Your healthcare team will explain how to dispose of the device and treatment materials safely.
What Happens During Treatment
The dtb-instiller procedure is straightforward and typically takes 15-30 minutes:
• You'll be positioned comfortably
• The area will be cleaned and prepared
• A thin catheter is gently inserted into your bladder
• Medication is delivered directly through the catheter
• The catheter is removed once treatment is complete
Quick Procedure
Usually completed in 15-30 minutes
Will using the dtb-instiller™ be uncomfortable?
Having a catheter inserted can cause discomfort. Tell your nurse or doctor if you feel pain during treatment so they can assess it and help you. Possible side effects also depend on the medicine you receive and your individual health. Delivering medicine directly into the bladder does not rule out side effects elsewhere in the body.
After Your Treatment
Most patients recover quickly and can return to normal activities within 24 hours
