Can A Urinary Tract Infection Be Prevented

Many methods have been suggested to reduce or prevent UTIs. The single most important prevention measure is increased fluid intake. Many people develop UTIs simply because they do not drink enough fluids. Some of these are considered home remedies and have been discussed . There are other suggestions that may help prevent UTIs. Good hygiene for males and females is useful. For females, wiping from front to back helps keep pathogens that may reside or pass through the anal opening away from the urethra. For males, retracting the foreskin before urinating reduces the chance of urine lingering at the urethral opening and acting as a culture media for pathogens. Incomplete bladder emptying and resisting the normal urge to urinate can allow pathogens to survive and replicate easier in a non-flowing system. Some clinicians recommend washing before and urinating soon after sex to reduce the chance of urethritis and cystitis. Many clinicians suggest that anything that causes a person irritation in the genital area may encourage UTI development. Wearing underwear that is somewhat adsorptive may help wick away urine drops that otherwise may be areas for pathogen growth.

Added Value Of This Study

Most patients diagnosed with lower UTI in primary care receive same-day empirical antibiotic therapy with little treatment diversity, generally limited to trimethoprim and nitrofurantoin, reflecting national guidelines. Microbiological investigation was undertaken infrequently and had little impact on treatment. The antibiotic re-prescription rate was low but gradually increased over time and was seen on average in over 3000 patients each year. Re-prescription of the same antibiotic occurred surprisingly frequently.

Diagnosing A Uti In Dogs

If you suspect that your dog has a bladder infection, she should see a vet right away. The vet will ask you questions about your dogs symptoms and history and do a thorough physical exam. A urine sample will be collected, and a complete urinalysis will show if there is blood, bacteria, or crystals in the urine. Often, a urine culture and sensitivity test is needed to help determine which antibiotics will be most effective against the specific bacteria.

In more serious cases, blood work, x-rays, and ultrasound tests are needed to see if any underlying conditions need to be treated. These may include diabetes, bladder stones, kidney disease, cancer, and more.

Antibiotics Or Nsaids For Uncomplicated Urinary Tract Infection

Pain relief and a delayed antibiotic prescription is a pragmatic and balanced approach

Urinary tract infection is second only to respiratory tract infection in the use of antibiotics. It is an international priority to rationalise antibiotic use in primary care given the dangers of antibiotic resistance and the evidence that prescribing in primary care is likely to be a key driver of antibiotic resistance.1 The trial by Kronenberg and colleagues 2 provides a welcome addition to the literature, providing a head-to-head comparison of an antibiotic compared with a non-steroidal anti-inflammatory drug and extending the findings of a previous German trial of antibiotics compared with the NSAID ibuprofen.3

The results show that an initial prescription for antibiotics is superior to NSAIDs for symptomatic management and inferior in terms of net antibiotic usage. However, the difference in symptom control may not be as stark as the 27% absolute difference in symptom resolution by day 3 would suggest, since the reduction in symptom score

Managing Lower Urinary Tract Infection

1.1.1 Be aware that lower urinary tract infection is an infection of the bladder usually caused by bacteria from the gastrointestinal tract entering the urethra and travelling up to the bladder.

1.1.2 Give advice about managing symptoms with self-care to all people with lower UTI.

Treatment for women with lower UTI who are not pregnant

1.1.3 Consider a back-up antibiotic prescription or an immediate antibiotic prescription for women with lower UTI who are not pregnant. Take account of:

• the severity of symptoms

• the risk of developing complications, which is higher in people with known or suspected structural or functional abnormality of the genitourinary tract or immunosuppression

• the evidence for back-up antibiotic prescriptions, which was only in non-pregnant women with lower UTI where immediate antibiotic treatment was not considered necessary

• previous urine culture and susceptibility results

• previous antibiotic use, which may have led to resistant bacteria

• preferences of the woman for antibiotic use.

1.1.4 If a urine sample has been sent for culture and susceptibility testing and an antibiotic prescription has been given:

• review the choice of antibiotic when microbiological results are available, and

• change the antibiotic according to susceptibility results if bacteria are resistant and symptoms are not already improving, using a narrow-spectrum antibiotic wherever possible.

Interactions That Increase Your Risk Of Side Effects

Taking metronidazole with certain medications raises your risk of side effects. This is because the amount of either drug may be increased in your body. Examples include:

• Lithium: Increased side effects are related to raised lithium levels. Your doctor should monitor your lithium levels if you take these drugs together.
• Warfarin or other blood thinners: Increased side effects of these drugs include a higher risk of bleeding.
• Busulfan: If possible, you should avoid taking busulfan with metronidazole. If you do take these drugs together, your doctor may check the amount of busulfan in your body more often.
• Cimetidine: Taking cimetidine with metronidazole may result in higher metronidazole levels in your body and increased side effects.
• Phenytoin or phenobarbital: Taking one of these drugs with metronidazole may reduce your bodys metronidazole levels. This could prevent metronidazole from curing your infection.

Levels Of Resistance To Metronidazole

Selected Published Data on the Distribution of Minimum Inhibitory Concentrations to Metronidazole among Clinical Isolates of Bacteroides fragilis

No significant clinical resistance to metronidazole or vancomycin in C. difficile strains has been reported. Some metronidazole-resistant C. difficile strains have been isolated however, they have seldom been isolated in toxigenic bacteria. In a study by Wong et al that reported the first well-documented case of a metronidazole-resistant C. difficile strain in a patient with C. difficile-associated diarrhea, 1 toxigenic-resistant isolate was detected among 100 strains . In a report from the Public Health Laboratory Service Anaerobe Reference Unit in the United Kingdom, no clinical isolate among > 10,000 tested strains was resistant, whereas only 1 resistant nontoxigenic strain was detected . Treatment failures are not uncommon but have not yet been clearly attributed to drug-resistant strains. In a 10-year prospective study of isolates from patients who experienced treatment failure, all isolates had an MIC of < 1 mg/L thus, a decreased susceptibility of the infecting C. difficile strains was not considered to be the cause of the failures .

Treatment Options For Dogs With Urinary Tract Infections

Treatment for UTI focuses on managing pain, giving antibiotics for bacterial UTIs. If there is an underlying cause, this must be addressed as well. Dogs with a recessed vulva often benefit from surgery which helps correct this problem. Some dogs with bladder stones can be treated by changing the diet. This helps prevent the future formation of stones in the bladder. For more information on bladder stones, click here!

Talk to your vet about other or alternative treatments such as supplements and/or acupuncture. Cranberry juice has not been proven to help dogs with UTI, but it can be offered to dogs along with their normal bowl of fresh water. Its important to note that cranberry juice or cranberry supplements are thought to improve bladder health and decrease the recurrence of UTI, but they will not cure a current bladder infection.

Make sure that your dog finishes all medications as directed by your vet. If your dog stops eating, has vomiting or diarrhea, or worsening of UTI symptoms while on medication, call your vet right away.

Follow up with your vet to recheck your dogs urine sample once the medication is finished. This will help determine if the UTI has cleared up or if your dog needs to continue treatment.

What Are Possible Complications Of A Urinary Tract Infection

Most UTIs cause no complications if they spontaneously resolve quickly or if treated early in the infection with appropriate medications. However, there are a number of complications that can occur if the UTI becomes chronic or rapidly advances.

• Chronic infections may result in urinary strictures, abscesses, fistulas, kidney stones, and, rarely, kidney damage or bladder cancer.
• The rapid advancement of UTIs can lead to dehydration, kidney failure, sepsis, and death.
• Pregnant females with untreated UTIs may develop premature delivery and low birth weight for the infant and run the risk of rapid advancement of the infection.

Treatment Strategies For Recurrent Utis

Recurrent urinary tract infections, defined as three or more UTIs within 12 months, or two or more occurrences within six months, is very common among women these but arent treated exactly the same as standalone UTIs. One of the reasons: Continued intermittent courses of antibiotics are associated with allergic reactions, organ toxicities, future infection with resistant organisms, and more.

Because of this, its strongly recommended that you receive both a urinalysis and urine culture from your healthcare provider prior to initiating treatment. Once the results are in, the American Urological Association suggests that healthcare professionals do the following:

• Use first-line treatments. Nitrofurantoin, TMP-SMX, and fosfomycin are the initial go-tos. However, specific drug recommendations should be dependent on the local antibiogram. An antibiogram is a periodic summary of antimicrobial susceptibilities that helps track drug resistance trends.
• Repeat testing. If UTI symptoms persist after antimicrobial therapy, clinicians should repeat the urinalysis, urine culture, and antibiotic susceptibility testing to help guide further management.
• Try vaginal estrogen. For peri- and post-menopausal women with recurrent UTIs, vaginal estrogen therapy is recommended to reduce risk of future UTIs.

What Are The Causes Of Urinary Tract Infections In Dogs

In most cases, UTIs are caused by bacteria, most commonly Escherichia Coli. They migrate from the outside through the urethra to the bladder. When the bladder is inflamed, this is called cystitis.

A dog that does not urinate often is more prone to bacterial urinary tract infections, as these bacteria have more time to migrate and develop in the bladder. Thats why its important to provide frequent wee breaks for your dog.

Some dogs are also more susceptible to UTIs and can have them repeatedly.

Diet plays an important role as well, as it influences the pH of the urine. A slightly acidic pH is preferred, as the bacteria develop more easily in an alkaline pH environment. See below how to help achieve this optimal pH level.

• Your dog has a harder time holding his bladder.
• They need to wee in small amounts, and more often.
• They start to have accidents in the house.
• Noticeable dripping after they have finished urinating .
• The urine looks darker and smelly.

In the case of a more advanced urinary tract infection, symptoms can change:

• Your pet seems in pain during urination, it seems forced.
• You notice blood in the urine.
• Your dog becomes incontinent .

What About Cranberry Juice For Uti

Its a long-held belief that consuming cranberry juice may help prevent and treat urinary tract infections. While its true that cranberries contain an active ingredient that can prevent adherence of bacteria to the urinary tract, there is still no evidence that cranberry products can treat a UTI.

One of the reasons: Products like cranberry juice or cranberry capsules are not explicitly formulated with the same amount of PACs that have shown potential in lab studies. Moreover, a 2019 report in the Journal of Urology noted that the availability of such products to the public is a severe limitation to the use of cranberries for UTI prophylaxis outside the research setting.

In all, theres actually very little high-quality research on the topic of prevention. For instance, a 2016 study in The Journal of the American Medical Association, found that among female nursing home residents, daily consumption of cranberry capsules resulted in no significant prevention of UTIs.

While consuming cranberry juice or supplements is not considered a first-line treatment of urinary tract infections, in most cases, it cant hurt. After all, drinking plenty of liquids does dilute your urine and help spur more frequent urination, which flushes bacteria from the urinary tract. The exception: Those who are taking blood-thinning medication, such as warfarin, should not consume cranberry juice. And those with diabetes should be mindful of the high-sugar content of fruit juices.

Patients who develop signs of pseudomembranous colitis after starting Cipro, Cipro XR should contact their doctor immediately.

What Is A Urinary Tract Infection

UTIs are common infections that happen when bacteria, often from the skin or rectum, enter the urethra, and infect the urinary tract. The infections can affect several parts of the urinary tract, but the most common type is a bladder infection .

Kidney infection is another type of UTI. Theyre less common, but more serious than bladder infections.
