The presence of the bacteria Pseudomonas in urine occurs when these organisms are able to transfer to the urethra and travel up into the urinary tract. They are found naturally in the feces and may migrate as a result of poor hygiene, sexual activity, or other factors. Treatment for this infection involves taking antibiotics to kill the organisms. The patient may need an evaluation in the future to check for a recurrence, a potential concern with urinary tract infections.
Bacteria can travel from the feces to the urethra, particularly in women. The relatively short length of the urethra in women increases the chances of transferring bacteria, especially for those who are sexually active. Although the body has some defenses to prevent infiltration of the urinary tract, they aren’t always successful. Older men can also be at risk because of obstructions like prostate enlargement that make it difficult to fully empty the bladder, which would normally flush bacterial invaders.
Some patients have traces of Pseudomonas in urine without any outward signs of infection. Others may develop symptoms like painful urination, low back pain, and bloody or cloudy urine. A culture can determine which organisms are present and may narrow down the Pseudomonas to a specific species. This can help medical professionals decide which antibiotics to recommend to address the infection. Medication needs to be taken even after patients feel better to make sure the organisms are completely eradicated.
It is also possible to introduce Pseudomonas in urine during a medical procedure if it is not performed in clean conditions. Inserting a catheter, urinary sound, or endoscopic device could push bacteria into the urinary tract if the patient isn’t prepared beforehand or the instruments are not clean. Maintaining sterile conditions throughout procedures is critical to address concerns about infection. Hospital-acquired infections are a persistent problem in some regions of the world. These may include resistant bacteria that are very difficult to treat and take advantage of immunocompromised hospital patients who may have few natural defenses.
There are some steps people can take to reduce the chance of transfer and limit the risk of Pseudomonas in urine. These can include always wiping from front to back when using the toilet, keeping the genitals and anal area clean, and being careful during sexual activity. Recurrent infections can become a problem for some patients and may be difficult to treat, as the organisms can develop resistance over time, making medications less effective and forcing patients to switch drugs periodically.
