How Do You Get Urinary Tract Infections

The design of the human body makes it so it isnt hard to get a bacterial UTI, because the infection comes from outside, through the urethra. Bacteria in the genital area can enter the urethra and the urinary tract, either because wiping after going to the bathroom, sexual activity, or unsanitary conditions. Once the bacteria have entered the urethra, the body tries fight them off, but sometimes the bacteria multiply and cause an infection.

In the case of a fungal infection, usually the fungus gets to the urinary tract through the blood stream. Those who develop this type of infection are usually ill with a disease that has compromised their immune system, such as AIDS.

In general, women get more UTIs than do men and this increases with age. Statistics show that many women get more than one. Almost 20% of women who have had one UTI will go on to have a second. Of this 20%, 30% of those will have a third, and in turn, 80% of these women will have more.

What Are The Types Of Utis

UTIs are categorized into two types.

Complicated UTIs refer to infections associated with another condition. Often, that underlying condition makes the UTI worse because it may involve pre-existing kidney or bladder problems. If left untreated, complicated UTIs can lead to severe, permanent kidney damage.

The other category of UTIs is an uncomplicated UTI. These occur in individuals who are otherwise healthy and do not have abnormalities in their urinary tract. Uncomplicated UTIs tend to be recurring. They are categorized based on where the infection develops along the urinary tract. If it develops in the bladder, its called cystitis if it grows in the kidney, its called pyelonephritis .

Over The Counter Uti Treatments

There are a few over-the-counter treatments available to soothe symptoms, though the Federal Drug Administration has only approved antibiotics for treatment in UTIs.

There are also some at-home remedies and lifestyle changes you can make to make yourself more comfortable, or prevent future or recurrent UTIs.

Your doctor may recommend phenazopyridine for pain relief, which can numb pain in the urinary tract. Another common OTC pain-reliever for UTIs is Cystex.

Please note that these are not replacements for antibiotics, and only relieve pain while waiting for them to work or until you can get a prescription.

Phenazopyridine will turn your urine a bright orange color and you should only use it for up to 2 days in a row maximum.

Some Facts About Pyelonephritis

What are some common antibiotics used to treat UTIs?
  • Acute pyelonephritis is a potentially life-threatening infection. In chronic pyelonephritis the kidney is damaged due to repeated or persistent infections and can even lead to kidney failure.
  • Pregnant women with bacteria in their urine are at risk of developing pyelonephritis particularly in the second and third trimesters.
  • The rise in the prevalence of drug-resistant bacteria has complicated the treatment of some cases of pyelonephritis.

First Are Antibiotics Necessary

Taking antibiotics should not be treated lightly, especially given the increased risk of developing multi-drug resistant bacteria like ESBL E.coli, for which we are running out of treatments.

  • While burning when you pee and the urge to urinate, are common UTI symptoms, they are not always indicative of a urinary tract infection.
  • Antibiotics alone are not as effective against mature bacterial biofilms.
  • An incomplete course or prophylactic antibiotics can actually promote the growth of bacterial biofilms.
  • Antioxidants, available in N-acetylcysteine supplements can increase the effectiveness of antibiotics and help you fight mature bacterial biofilms.
  • Natural supplements like D-Mannose can be effective at the first sign of a UTI and dont come with the extensive side effect profile of many antibiotics

Therefore, you and your physician should ensure that necessary testing is done before prescribing antibiotics. This includes analyzing accurate local antibiotic resistance data to make sure you get the best empirical antibiotics until more data is available.

Complicated & Recurrent Uti

Antibiotics should never be selected empirically for complicated UTI without culture susceptibility results . Management of pyelonephritis, prostatitis, and relapsing or recurrent UTI is often unsuccessful without therapy guided by culture and susceptibility results. However, therapy should be instituted while culture and susceptibility results are being awaited. Rational initial drug choices for complicated UTI include amoxicillin, fluoroquinolones, or trimethoprim-sulfonamide.3

What Oral Antibiotics Are Used To Treat An Uncomplicated Uti In Women

The following oral antibiotics are commonly used to treat most uncomplicated UTI infections :

Your doctor will choose your antibiotic based on your history, type of UTI, local resistance patterns, and cost considerations. First-line options are usually selected from nitrofurantoin, fosfomycin and sulfamethoxazole-trimethoprim. Amoxicillin/clavulanate and certain cephalosporins, for example cefpodoxime, cefdinir, or cefaclor may be appropriate options when first-line options cannot be used.

Length of treatment for cystitis can range from a single, one-time dose, to a course of medication over 5 to 7 days. Kidney infections may require injectable treatment, hospitalization, as well as a longer course of antibiotic, depending upon severity of the infection.

Sometimes a UTI can be self-limiting in women, meaning that the body can fight the infection without antibiotics however, most uncomplicated UTI cases can be treated quickly with a short course of oral antibiotics. Never use an antibiotic that has been prescribed for someone else.

In men with symptoms that do not suggest a complicated UTI, treatment can be the same as women. In men with complicated UTIs and/or symptoms of prostatitis are not present, men can be treated for 7 days with a fluoroquinolone . Tailor therapy once urine cultures are available.

Antibiotics Used For Complicated Utis

medical.net: TREATMENT OF URINARY TRACT INFECTIONS

Before getting into how to best treat a complicated UTI, its important to understand which UTIs are considered complicated. Here are some guidelines:

  • Urinary tract abnormalities are present
  • Youre pregnant
  • The patient is a child
  • A comorbidity is present that increases risk of infection or treatment resistance, such as poorly controlled diabetes
  • Youre a man, since most UTIs in men are considered complicated

Kidney infections are often treated as a complicated UTI as well, notes the Merck Manual.

If a UTI is complicated, a different course of antibiotics may be required. And the initial dose of antibiotics may be started intravenously in the hospital. After that, antibiotics are given orally at home. In addition, follow-up urine cultures are generally recommended within 10 to 14 days after treatment. Not all of the antibiotics approved for uncomplicated UTIs are appropriate for the complicated version. Some that are considered appropriate, include:

How Relevant Is This To My Practice

Uncomplicated lower UTI remains one of the most commonly treated infections in primary care. The urinary tract is a common source of infection in children and infants and is the most common bacterial infection in children < 2 years of age, both in the community and hospital setting. During the first six months of life, UTIs are more common in boys. The outcome is usually benign, but UTIs can progress to renal scarring in early infancy, especially when associated with congenital anomalies of the urinary tract. Renal scarring may lead to complications in adulthood including hypertension, proteinuria, renal damage and even chronic renal failure, which requires dialysis treatment.

In general, 40% of women develop a UTI at some point in their life. In Singapore, 4% of young adult women are affected and the incidence increases to 7% at 50 years of age. Adult women are 30 times more likely than men to develop a UTI, with almost half of them experiencing at least one episode of UTI during their lifetime. It is reported that one in three women have their first episode of UTI by the age of 24 years. UTIs are most commonly seen in sexually active young women. Other susceptible adults include the elderly and patients requiring urethral catheterisation.

    Other antibiotics appear to be overused, and some physicians may misuse non-recommended antibiotics as first-line treatments. Ciprofloxacin is used in 35% of uncomplicated UTIs, while levofloxacin is used in 2%. These antibiotics can be important treatments in some cases of more complicated UTIs, but can have dangerous side effects.

    The U.S. Food and Drug Administration warns that the use of these drugs should be restricted because of their potentially disabling side effects involving tendons, muscles, joints, nerves and the central nervous system. Additionally, in many parts of the country, bacteria commonly causing UTIs are becoming resistant to these antibiotics.

    Fungal Urinary Tract Infection

    Fungal UTI is uncommon. As with bacterial UTI, fungal UTI occurs because of temporary or permanent breaches in local or systemic immunity of the lower urinary tract. Funguria may be due to primary infections of the lower urinary tract or secondary to shedding of fungal elements into the urine in animals with systemic infections. Primary fungal UTI is most commonly due to Candida spp, a commensal inhabitant of the genital mucosa, upper respiratory tract, and gastrointestinal tract., Candida albicans is the most commonly identified species, followed by Candida glabrata and Candida tropicalis other ubiquitous fungi may also occasionally cause primary fungal UTI, including Aspergillus spp, Blastomycosis spp , and Cryptococcus spp.

    Is It Possible To Prevent Recurrent Urinary Tract Infections With A Vaccine

    Currently, there are no commercially available vaccines for UTIs, either recurrent or first-time infections. One of the problems in developing a vaccine is that so many different organisms can cause infection a single vaccine would be difficult to synthesize to cover them all. Even with E. coli causing about most infections, the subtle changes in antigenic structures that vary from strain to strain further complicates vaccine development even for E. coli. Researchers are still investigating ways to overcome the problems in UTI vaccine development.
