Installation of BCG Into the Bladder

You are about to receive medication into your bladder. This is done by inserting a catheter into the opening of the urethra, then into the bladder.  When the catheter is in the bladder, medication (BCG) will be passed through the catheter into the bladder. This is called a bladder instillation. You will receive your BCG treatment via this method.  The usual course of treatment is once a week for six weeks. Treatment may be postponed depending on urinalysis.

Before Instillation

Back to top
  • Please be on time for your instillation treatment
  • Do not drink fluids for at least 2 hours before you receive your treatment
  • Inform your doctor if you have felt feverish, tired or had chills since your last treatment or if you have been urinating any bright red blood before your instillation
  • Empty your bladder just before the instillation and give urine specimen to the nurse to check

During Instillation

Back to top
  • The medication will be instilled into your bladder through the catheter
  • In most cases, the catheter will be removed from the bladder after the instillation is completed
  • The medication should be retained in your bladder for 2 hours to obtain the best results

After Instillation

You should change positions several times once you get home.  Ideally, you should reposition from left side to right side and also lie upon your back and your abdomen, changing these positions every 15 minutes to maximize bladder exposure to the medication for one hour.

Now that you have retained the medication in your bladder for the past two hours, there are several things you must do:

  • Sit down on the toilet to urinate and fully empty your bladder.
  • After urinating, pour two (2) cups of household bleach (Clorox or equivalent) into the toilet for 15-20 minutes before flushing.
  • Repeat the above process each time you urinate for six (6) hours after each treatment
  • Wash your hands and genital area thoroughly after you urinate
  • Drink plenty of fluids after your instillation to flush your bladder.
