</div></div><div class="section-body" id="section-1"><p>Urinary catheters are used to drain the bladder. Your health care provider may recommend that you use a catheter if you have:</p><ul><li>Urinary incontinence (leaking urine or being unable to control when you urinate)</li><li>Urinary retention (being unable to empty your bladder when you need to)</li><li>Surgery on the prostate or genitals</li><li>Other medical conditions such as <a test="test" href="./000737.htm">multiple sclerosis</a>, spinal cord injury, <a test="test" href="./000739.htm">dementia</a>, or other operations</li></ul><p>Catheters come in many sizes, materials (latex, silicone, Teflon), and types (straight or coude tip). A Foley catheter is a common type of indwelling catheter. It has soft, plastic or rubber tube that is inserted into the bladder to drain the urine.</p><p>In most cases, your provider will use the smallest catheter that is appropriate.</p><p>There are 3 main types of catheters:</p><ul><li>Indwelling catheter</li><li>Condom catheter</li><li>Intermittent self-catheter </li></ul><p>INDWELLING URETHRAL CATHETERS </p><p>An indwelling urinary catheter is one that is left in the bladder. You may use an indwelling catheter for a short time or a long time.</p><p>An indwelling catheter collects urine by attaching to a drainage bag. The bag has a valve that can be opened to allow urine to flow out. Some of these bags can be secured to your leg. This allows you to wear the bag under your clothes. An indwelling catheter may be inserted into the bladder in 2 ways:</p><ul><li>Most often, the catheter is inserted through the urethra. This is the tube that carries urine from the bladder to the outside of the body.</li><li>Sometimes, the provider will insert a catheter into your bladder through a small hole in your lower belly. This is done at a hospital or provider's office. </li></ul><p>An indwelling catheter has a small balloon inflated on the end of it. This prevents the catheter from sliding out of your body. When the catheter needs to be removed, the balloon is deflated.</p><p>CONDOM CATHETERS </p><p>Condom catheters can be used by men with incontinence. There is no tube placed inside the penis. Instead, a condom-like device is placed over the penis. A tube leads from this device to a drainage bag. The condom catheter must be changed every day.</p><p>INTERMITTENT CATHETERS </p><p>You would use an intermittent catheter when you only need to use a catheter sometimes or you do not want to wear a bag. You or your caregiver will insert the catheter to drain the bladder and then remove it. This can be done only once or several times a day. The frequency will depend on the reason you need to use this method or how much urine needs to be drained from the bladder.</p><p>DRAINAGE BAGS </p><p>A catheter is most often attached to a drainage bag.</p><p>Keep the drainage bag lower than your bladder so that urine does not flow back up into your bladder. Empty the drainage device when it is about one half full and at bedtime. Always wash your hands with soap and water before emptying the bag.</p><p>HOW TO CARE FOR A CATHETER </p><p>To care for an indwelling catheter, clean the area where the catheter exits your body and the catheter itself with soap and water every day. Also clean the area after every bowel movement to prevent infection.</p><p>If you have a suprapubic catheter, clean the opening in your belly and the tube with soap and water every day. Then cover it with dry gauze.</p><p>Drink plenty of fluids to help prevent infections. Ask your provider how much you should drink.</p><p>Wash your hands before and after handling the drainage device. DO NOT allow the outlet valve to touch anything. If the outlet gets dirty, clean it with soap and water.</p><p>Sometimes urine can leak around the catheter. This may be caused by:</p><ul><li>A catheter that is blocked or that has a kink in it</li><li>A catheter that is too small in diameter</li><li>Bladder <a test="test" href="./003193.htm">spasms</a></li><li><a test="test" href="./003125.htm">Constipation</a></li><li>The wrong balloon size</li><li><a test="test" href="./000521.htm">Urinary tract infections</a></li></ul><p>POSSIBLE COMPLICATIONS </p><p>Complications of catheter use include:</p><ul><li>Allergy or sensitivity to latex</li><li><a test="test" href="./001275.htm">Bladder stones</a></li><li>Blood infections (<a test="test" href="./001355.htm">septicemia</a>)</li><li><a test="test" href="./003138.htm">Blood in the urine</a> (hematuria)</li><li>Kidney damage (usually only with long-term, indwelling catheter use)</li><li><a test="test" href="./001063.htm">Urethral injury</a></li><li>Urinary tract or kidney infections</li><li>Bladder cancer (only after long-term indwelling catheter) </li></ul><p>Contact your provider if you have:</p><ul><li>Bladder spasms that do not go away</li><li>Bleeding into or around the catheter</li><li><a test="test" href="./003090.htm">Fever</a> or chills</li><li>Large amounts of urine leaking around the catheter</li><li>Skin sores around a suprapubic catheter</li><li>Stones or sediment in the urinary catheter or drainage bag</li><li>Swelling of the urethra around the catheter</li><li>Urine with a strong smell, or that is thick or cloudy</li><li>Very little or no urine draining from the catheter and you are drinking enough fluids </li></ul><p>If the catheter becomes clogged, painful, or infected, it will need to be replaced right away.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Alternative Names</h2></div><div class="section-button"><button type="submit" aria-controls="section-Alt" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
