This is to make sure that all of the bacteria are gone. Normal Results "Normal growth" is a normal result. This means that there is no infection.Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results. What Abnormal Results Mean A "positive" or abnormal test is when bacteria or yeast are found in the culture. This likely means that you have a urinary tract infection or bladder infection.Other tests may help your provider know which bacteria or yeast are causing the infection and which antibiotics will best treat it, if treatment is needed.Sometimes more than one type of bacteria, or only a small amount, may be found in the culture. Risks There is a very rare risk for a hole (perforation) in the urethra or bladder if your provider uses a catheter. Considerations You may have a false-negative urine culture if you have been taking antibiotics.Open ReferencesReferencesCooper KL, Badalato GM, Rutman MP. Infections of the urinary tract.

You go, you flush, you wash. But sometimes, you can have a condition that makes it painful or difficult to go. If you're feeling pain or burning when you urinate, or you feel like you need to go all the time, the problem could be a urinary tract infection. Most often, you get a urinary tract infections when bacteria make their way into your bladder, kidneys, ureters, those tubes that carry urine from the kidneys to the bladder, or the urethra, the tube that carries urine to the outside of your body. Unfortunately for women, they're more likely to get a urinary tract infection than men because they have a much shorter urethra. Bacteria can more easily slip into a woman's body after they have sex or use the bathroom. Certain conditions can also increase your risk of a urinary tract infection, including diabetes, pregnancy, kidney stones, an enlarged prostate in men, as well as urinary tract surgery. You can often tell you may have a urinary tract infection by the pain and burning whenever you urinate, and the constant urge to go. Your urine may look cloudy or bloody, and it might give off a bad smell. Your doctor can diagnose an infection by taking a urine sample and checking for bacteria. Occasionally different scans, including a CT and kidney scan, may be done to rule out other urinary problems. If you do have a urinary tract infection, you'll probably be prescribed antibiotics, drugs that kill bacteria. Also drink a lot of water and other fluids to help flush out the bacteria. Usually, antibiotics can knock out a urinary tract infection in a day or two. But like the unwelcome visitors they are, sometimes these infections keep coming back. You may need to keep taking antibiotics for a longer period of time. There are ways to help prevent getting urinary tract infections, like drinking a lot of fluids, perhaps including cranberry juice. Probiotics, beneficial bacteria may also help prevent urinary tract infections. Women should be careful about their hygiene. Always wipe from front to back after using the bathroom, urinate before and after sexual activity, and keep your genital area clean. If you use a diaphragm with spermicide, consider changing contraceptives. For post menopausal women, topical estrogen greatly reduces urinary tract infections. Recurrent, uncomplicated urinary tract infections are very common in non pregnant, healthy young women. Thankfully, they are easy to treat and are unlikely to lead to other health problems.Urine sample - illustration A clean-catch urine sample is performed by collecting the sample of urine in midstream. Men or boys should wipe clean the head of the penis. Women or girls need to wash the area between the lips of the vagina with soapy water and rinse well. A small amount of urine should initially fall into the toilet bowl before it is collected (this clears the urethra of contaminants). Then, in a clean container, catch about 1 to 2 ounces of urine and remove the container from the urine stream. The container is then given to the health care provider.Urine sampleillustrationFemale urinary tract - illustration The female and male urinary tracts are relatively the same except for the length of the urethra.Female urinary tractillustrationMale urinary tract - illustration The male and female urinary tracts are relatively the same except for the length of the urethra.Male urinary tractillustrationUrinary tract infection - adultsAnimation Related video goes here for no-HTML5 browsersUrinary tract infection - adults - Animation Using the bathroom is usually a no-brainer.
