It is the most common bacterial infection in humans is only exceeded by the influenza A viral origin. It is the presence of bacteria in the urine. These bacteria multiply over time, as adequate treatment is instituted. The bacteria can attack any level of the urinary tract from the bladder causing cystitis, until the kidney, causing pyelonephritis. Urinary infections are more common in women and in men in old age.
What is it?
The urinary tract infection is the presence of microorganisms in some part of the urinary tract. Arise when the kidney is called pyelonephritis, bladder, cystitis, prostate, prostatitis and urethra, arthritis.
Most of the URINARY TRACT is caused by bacteria, but can also be caused by viruses, fungi and other microorganisms. Most urinary infections occur by the invasion of some bacteria of intestinal bacterial flora in the urinary tract.
Sometimes the patient presents symptoms similar to UTI, such as pain, burning, urgency to urinate and increased frequency, but tests show no bacteria culture in the urine.
These cases can be confused with urinary incontinence and are called acute urethral syndrome, which may have other non-infectious causes, but of inflammatory origin, such as chemical, toxic, hormonal and irradiation.
How does it occur?
The access of microbes to the urinary tract occurs via ascending, or the urethra and can be installed in the urethra and prostate gland itself, advancing to the bladder and with more difficulty for the kidney.
Rarely, bacteria can enter the urinary tract by the bloodstream. This occurs only when there is widespread infection or in individuals without immune defenses such as AIDS and transplant recipients. The intensity of URINARY TRACT depends on the patient's defenses, the virulence of the microorganism and the ability to adhere to the wall of the urinary tract.
As urine is sterile, there are factors that facilitate the contamination of the urinary tract, such as:
Urinary obstruction: enlarged prostate, urethral stenosis, congenital defects and other Foreign bodies: catheters, calculi (kidney stones), introduction of objects into the urethra Neurological diseases: head of the column, neurogenic bladder of diabetes Fistulas genital -urinary and digestive tract, and constipated colostomies Sexually transmitted diseases and gynecological infections.
What does it feel? The urination is voluntary and painless. The presence of: Pain Burning Difficulty and urgent urination Frequent urination and urinary very small volume With urine odor, color opaque With strands of mucus
Form a data set that allows the physician to suspect the patient has urinary tract infection. Often added to these signs and symptoms and pain in the bladder at the end of urination, drips small amounts of blood.
When the kidney is achieved, the patient presented, besides the above symptoms, chills, fever and backache, which can sometimes occur abdominal cramps, nausea and vomiting.
