Urinary Tract Infection, second only to respiratory infection as the most common type of infection

Urinary Tract Infection, second only to respiratory infection as the most common type of infection

A urinary tract infection (UTI) is an infection involving the kidneys, ureters, bladder, or urethra. These are the structures that urine passes through before being eliminated from the body.

UTI is the most common disease related to the urinary apparatus and even to the whole organism excepting from the respiratory diseases. Around 150 million UTI cases are detected yearly worldwide, being basically a pathology suffered by women. The reason for this is not well understood, but anatomic differences between the genders (a shorter urethra in women) might be partially responsible. It is also the most common infection in the hospital environment.

What causes UTI?

The urine is normally sterile. An infection occurs when bacteria get into the urine and begin to grow. The infection usually starts at the opening of the urethra where the urine leaves the body and moves upward into the urinary tract.

The culprit in at least 90% of uncomplicated infections is a type of bacteria called Escherichia coli, better known as E. coli. These bacteria normally live in the bowel (colon) and around the anus. These bacteria can move from the area around the anus to the opening of the urethra. The two most common causes of this are improper wiping and sexual intercourse.

Usually, the act of emptying the bladder (urinating) flushes the bacteria out of the urethra. If there are too many bacteria, urinating may not stop their spread. The bacteria can travel up the urethra to the bladder, where they can grow and cause an infection.

What are urinary tract infection symptoms and signs?

·       Bladder (cystitis): The lining of the urethra and bladder becomes inflamed and irritated.

·       Dysuria: Pain or burning during urination

·       Frequency: More frequent urination (or waking up at night to urinate, sometimes referred to as nocturia); often with only a small amount of urine

·       Urinary urgency: The sensation of having to urinate urgently

·       Cloudy, bad-smelling, or bloody urine

When should people seek medical care for a UTI?

Any adult or child who develops any of the symptoms of a urinary tract infection needs to be evaluated by a medical professional, preferably within 24 hours. Someone who has symptoms of a lower urinary tract infection should call a health-care professional for an appointment, preferably on the same day that symptoms are recognized.

Someone who has symptoms of an upper urinary tract infection involving the kidneys should call a health-care professional immediately. Depending on the situation, he or she will recommend either a visit to the office or to a hospital emergency department.

Is it possible to prevent a urinary tract infection?

·       Women and girls should wipe from front to back (not back to front) after bowel movements. This helps prevent bacteria from the anus entering the urethra.

·       Empty the bladder regularly and completely, especially after sexual intercourse.

·       Drink plenty of fluids, especially water.

·       Cranberry juice, especially, has been shown to help prevent urinary tract infections.

·       Women should empty the bladder soon after sexual intercourse.

As above said, UTI is one of the most common diseases worldwide and, therefore, MedicalDays collaborates with an excellent partner with this regard. With modern facilities and equipped with the latest technology, the IVU (Instituto Valenciano de Urología) is the best medical center for the medical and surgical treatment of diseases and problems arising in the kidney, prostate, bladder and genitals in both men and women.
