A Foley catheter is a sterile tube that is thin enough to be inserted into the bladder to help facilitate the draining of urine. Also called an indwelling catheter and available as a male catheter or female catheter, it is designed to be left in your bladder for an extended period of time and is held in place by a balloon filled with sterile water at the end. The urine drains into a catheter bag, which can then be tested in a laboratory for kidney function, electrolytes, muscle breakdown, crystals, blood and infection.
A Foley catheter is used with various problems, procedures and disorders such as:
- After surgery.
- Sterile urine collection.
- Bladder dysfunction related to nerve damage from spinal trauma.
- Urine output monitoring in an injured or critically ill patient.
- Prostate cancer, prostate hypertrophy or the narrowing of the urethra, all of which are obstructions of the urethra that complicate the urinary process.
- Urinary retention leading to sensation of incomplete emptying, straining to urinate, interruption of urinary stream, decrease in force and size of urinary stream and urinary hesitancy.
Here are some risks of using a Foley catheter:
- There is a possibility of the balloon breaking when the catheter is being inserted. If this happens, the doctor will have to carefully remove all of the balloon fragments.
- Urine flow may be blocked upon introduction of the Foley catheter. The doctor will then have to change the Foley catheter, the catheter bag or both.
- Bleeding in the urethra may occur. The doctor will have to monitor the bleeding so complications don't occur.
- If the Foley catheter is not completely inserted into the bladder and the balloon opens up, damage, bleeding and even rupture of the urethra can occur.
