Bladder instillations

Your consultant urologist will insert an antiseptic gel into your urethra (waterpipe) to numb it. They'll then pass a catheter (soft, thin tube) into your bladder. After emptying it of any remaining urine, they'll instill (inject) a liquid medication into your bladder to treat the pain.

You'll be asked to limit your fluid intake prior to your treatment. When you arrive at the clinic, we'll ask you to pass urine, which we'll test for infection. If your urine is clear, your urologist will briefly review your history and medications. They'll also explain the procedure and answer any questions you might have. Like all procedures, there may be some risks and side effects involved. Your consultant will explain these to you. Your consultant will inform you on how many instillation you will require on a once weekly basis.

After removing your catheter, we'll ask you to not pass any urine for at least 30 minutes (possibly 90 minutes) to allow the medication to treat the entire bladder lining. Your consultant will let you know when you can get back to your usual routine, including work or exercise.
