Using a urinary catheter at home is a straightforward process once you learn the steps. Most people who self-catheterize use an intermittent catheter, a thin flexible tube inserted through the urethra to drain the bladder and then removed. The first few times can feel intimidating, but the technique becomes routine quickly. Here’s what you need to know about preparation, insertion, and care.
Types of Urinary Catheters
The two main types are intermittent catheters and indwelling catheters, and they work very differently. An intermittent catheter is inserted each time you need to empty your bladder, then pulled out. You’ll typically do this four to six times a day, depending on how much fluid you drink and how your bladder functions. An indwelling catheter (sometimes called a Foley catheter) stays in place for days or weeks, held inside the bladder by a small inflated balloon, and drains continuously into a collection bag.
If you’re learning to catheterize yourself at home, you’re almost certainly using intermittent catheters. They carry a lower risk of urinary tract infections compared to indwelling catheters because they spend far less time inside the body. Prolonged catheter use is the single biggest risk factor for catheter-associated UTIs.
Supplies You’ll Need
Gather everything before you start so you don’t have to interrupt the process with unclean hands. You’ll need:
- A catheter in the size your provider prescribed, opened and ready to use
- Lubricant, either a water-based gel or a pre-lubricated catheter
- A cleaning wipe or antiseptic towelette
- A collection container if you won’t be sitting over a toilet
- Disposable gloves (optional, and they don’t need to be sterile unless your provider specifies)
Some catheters come pre-coated with a hydrophilic surface. These have a polymer coating that absorbs water and becomes very slippery, so you don’t need to apply lubricant separately. Most come prepackaged in sterile water, or include a small pouch of water you break open before use. In clinical studies, people using hydrophilic catheters reported significantly less discomfort during insertion compared to standard catheters, and found them easier to insert and remove.
If you’re using a standard uncoated catheter, apply a water-based lubricant (like K-Y Jelly) to the tip and the first two inches of the catheter. Never use petroleum-based products like Vaseline, which can damage the catheter material and irritate the urethra.
Step-by-Step Insertion for Males
Wash your hands thoroughly with soap and water. Clean the tip of your penis with an antiseptic wipe, soap and water, or a baby wipe. If you’re uncircumcised, retract the foreskin first. Hold the penis at a slight upward angle to straighten the natural curve of the urethra, which helps the catheter pass more easily.
Gently insert the lubricated catheter into the urethral opening. Advance it slowly and steadily. You may feel mild pressure or a brief sensation of needing to urinate as the catheter passes through the prostate area. This is normal. Continue until urine begins to flow, then push about one more inch further to make sure the tip is fully inside the bladder.
Let the urine drain completely. When the flow stops, slowly withdraw the catheter, pausing if more urine flows out. Once removed, dispose of the catheter (if single-use) or clean it according to your provider’s instructions.
Step-by-Step Insertion for Females
The biggest challenge for women is locating the urethral opening, which sits between the clitoris and the vaginal opening. If you’ve never looked at this area, use a mirror the first few times. Wash your hands, then clean the area from front to back with an antiseptic wipe or soap and water.
Spread the labia with your non-dominant hand and keep them apart throughout the process. With your other hand, gently insert the lubricated catheter into the urethral opening until urine starts flowing. The urethra is shorter in women, so the catheter won’t need to go in as far. Let the bladder drain completely, then slowly remove the catheter.
If you accidentally insert the catheter into the vagina, remove it and try again with a fresh catheter. This is a common mistake early on and nothing to worry about.
What to Do if You Feel Resistance
Mild resistance during insertion is common, especially for men. The urethra has a few natural narrow points where the catheter may not glide through immediately. The most important thing is to never force the catheter. Stop, take a few slow breaths, and try to relax your pelvic floor muscles. Bearing down slightly, as if you’re trying to urinate, can help open the sphincter and allow the catheter to pass.
For men, making sure the penis is held at a gentle upward angle helps straighten the urethra’s curve. If standard catheters consistently cause difficulty, a coudé catheter (which has a slight curved tip) can navigate around obstructions in the prostate area or deeper urethra more easily. Your provider can prescribe one if needed.
For women, changes in anatomy from aging, childbirth, or reduced estrogen after menopause can make the urethral opening harder to find or reach. The tissue can thin out and the opening can shift position. If you consistently struggle to locate or access it, your provider can show you alternative positioning techniques.
How Often to Catheterize
Most people on an intermittent catheterization schedule drain their bladder four to six times per day, roughly every four to six hours. Your provider will set a schedule based on your fluid intake and bladder capacity. The goal is to avoid letting the bladder overfill, which can stretch the bladder wall and increase the risk of infection or leakage.
Keep a rough mental note of how much urine drains each time. If you’re consistently getting very large volumes, you may need to catheterize more frequently. If you’re getting very small amounts, you may be able to extend the interval slightly. Your provider can help adjust the schedule.
Reducing Your Risk of Infection
Urinary tract infections are the most common complication of catheter use. Clean technique is your strongest defense. That means washing your hands before every catheterization, cleaning your genital area before insertion, and keeping the catheter itself clean until it enters the urethra. Don’t touch the insertion end of the catheter to any surface.
Other practices that help: drink enough water throughout the day to keep urine flowing regularly, use a new catheter for each session if your insurance covers single-use supplies, and don’t skip scheduled catheterizations (stagnant urine in the bladder is a breeding ground for bacteria).
Caring for an Indwelling Catheter
If you have an indwelling catheter with a drainage bag, daily maintenance is important. Clean where the catheter enters the body with soap and water every day. Keep the drainage bag below the level of your bladder at all times so urine flows downward by gravity. Don’t let the bag touch the floor.
Empty the bag when it’s about half to two-thirds full. Clean the drainage bag every two to three weeks by rinsing it with hot water, then filling it with a solution of one part white vinegar to three parts tap water. Let it soak for 20 minutes, then rinse thoroughly. This prevents bacterial buildup inside the bag.
Watch for signs of blockage: no urine draining into the bag for several hours, feeling of bladder fullness or pressure, or urine leaking around the catheter. Leakage around the catheter can also happen from bladder spasms or during bowel movements, which is common and not always a sign of a problem.
Signs That Need Immediate Attention
Contact your healthcare provider right away if you notice blood clots or large solid pieces coming from the catheter, if you develop a fever alongside catheter use, or if your catheter appears completely blocked and you cannot drain urine at all. Pain that worsens over time, cloudy or foul-smelling urine with fever, or new swelling around the catheter site also warrant a prompt call. These can signal infection, injury, or a blockage that needs professional management.
