Hydrodistention is a procedure to examine the bladder. During hydrodistention, the bladder is filled with sterile fluid until it is more full than normal (distended). This makes it easier to see the bladder walls clearly. To do this procedure, a thin, tube-shaped instrument with a light and a tiny camera at the end (cystoscope) is passed through the urethra and into the bladder.
This procedure is commonly done to help diagnose a condition that causes inflammation of the bladder (interstitial cystitis). It may also be done to remove a sample of bladder tissue to be checked under a microscope (biopsy).
Tell a health care provider about:
- Any allergies you have.
- All medicines you are taking, including vitamins, herbs, eye drops, creams, and over-the-counter medicines.
- Any problems you or family members have had with anesthetic medicines.
- Any blood disorders you have.
- Any surgeries you have had.
- Any medical conditions you have.
- Whether you are pregnant or may be pregnant.
- Allergic reactions to medicines.
- Damage to the bladder or other structures or organs.
- Difficulty urinating.
- Temporary inability to urinate.
- Worsening pain.
- Ask your health care provider about:
- Changing or stopping your regular medicines. This is especially important if you are taking diabetes medicines or blood thinners.
- Taking medicines such as aspirin and ibuprofen. These medicines can thin your blood. Do not take these medicines before your procedure unless directed by your health care provider.
- Follow instructions from your health care provider about eating or drinking restrictions.
- Do not use any tobacco products, such as cigarettes, chewing tobacco, and electronic cigarettes. If you need help quitting, ask your health care provider.
- You may be given antibiotic medicine to help prevent infection.
- You may have an exam or testing.
- You may have a blood sample taken.
- You may have urine tests to check for signs of infection.
- Plan to have someone take you home after the procedure.
- If you will be going home right after the procedure, plan to have someone with you for 24 hours.
What Happens During The Procedure?
- An IV tube will be inserted into one of your veins.
- You will be given one or more of the following:
- A medicine to help you relax (sedative).
- A medicine to numb the area (local anesthetic).
- A medicine to make you fall asleep (general anesthetic).
- A medicine that is injected into your spine to numb the area below and slightly above the injection site (spinal anesthetic).
- The cystoscope will be inserted through your urethra and into your bladder.
- Fluid will be pumped through the cystoscope and into your bladder until your bladder is distended. The amount of fluid that is needed to fill your bladder will be measured.
- Your health care provider will look at the inside of your bladder. If a biopsy is needed, a sample of bladder tissue may be removed.
- Fluid will be drained from your bladder, and the cystoscope will be removed.
Post Procedure Care
- Your blood pressure, heart rate, breathing rate, and blood oxygen level will be monitored often until the medicines you were given have worn off.
- You may continue to receive fluids and medicines through an IV tube.
- You may have some blood in your urine.
- Do not drive for 24 hours if you received a sedative.
