Foley catheterization is a medical procedure in which a flexible tube is inserted into the urinary bladder through the urethra to drain urine, typically performed by a trained nurse or doctor under sterile conditions.
A Foley catheter (indwelling urinary catheter) is a thin, sterile tube with a balloon at its tip that is inserted into the bladder to provide continuous drainage of urine. Once properly placed, the balloon is inflated with sterile water to hold the catheter in position inside the bladder.
This procedure is performed in patients who:
Cannot urinate naturally (urinary retention).
Need accurate urine output monitoring (critical/ICU patients).
Are undergoing surgery or anesthesia.
Require long-term bladder drainage (neurological or mobility conditions).
The process must be carried out with strict aseptic technique to prevent Urinary Tract Infections (UTIs).
Confirm doctor’s order and patient consent.
Gather sterile catheterization kit, gloves, antiseptic solution, and drainage bag.
Explain procedure to patient for comfort and cooperation.
Wash hands and wear sterile gloves.
Position patient appropriately (supine, legs apart).
Clean genital area with antiseptic solution.
Gently insert Foley catheter into the urethra until urine flows.
Inflate balloon with sterile water to secure catheter inside bladder.
Connect catheter to urine drainage bag.
Ensure catheter and tubing are properly positioned without kinks.
Educate patient about hygiene and catheter care.
Monitor urine color, amount, and possible signs of infection.
Document procedure (date, time, catheter size, patient response).
