Overview
- Cystitis (sis-TIE-tis) is the medical term for inflammation of the bladder. Most of the time, the inflammation is caused by a bacterial infection, and it's called a urinary tract infection (UTI). A bladder infection can be painful and annoying, and it can become a serious health problem if the infection spreads to your kidneys.Less commonly, cystitis may occur as a reaction to certain dru…
- Vaginal Estrogen. Estrogen reduces risk of recurrent UTI by repopulating the normal vaginal lactobacilli that keep bacteria from the rectum from multiplying and causing a bladder infection. Forms of vaginal estrogen are available at very low dosages that have minimal systemic absorption. Vaginal estrogen is a medication that needs to be prescribed by your doctor.
- A bladder infection is an illness caused by bacteria. Bladder infections are the most common type of urinary tract infection (UTI). A UTI can develop in any part of your urinary tract, including your urethra, bladder, ureters, or kidneys.
Treatment
- Doctors treat lower and upper urinary tract infections with antibiotics. Laboratory testing can determine the best antibiotic for treatment. Most uncomplicated lower tract infections are treated with a three-day course of antibiotics, although women who are pregnant, or who have diseases such as diabetes that suppress the immune system, usually need to take antibiotics for longer.P…
- Your doctor will determine if you have a UTI by asking about symptoms, doing a physical examination, and ordering urine tests, if needed.UTIs are caused by bacteria and are treated with antibiotics. However, any time you take antibiotics, they can cause side effects. Side effects can range from minor reactions, such as a rash, to very serious health problems, such as antibiotic-r…
- Antibiotics are the first-line treatment for UTIs, but some strains of E. coli, called extended-spectrum beta-lactamase (ESBL) E. coli, have become more resistant to many of these drugs, including ampicillin and tetracycline. While ESBLs can break down many antibiotics, making them ineffective, it cannot do the same with a specific class of antibiotics called carbapenems. Thes…
- Most dogs recover without complications once the appropriate antibiotics are administered. However, it is important to identify the issue quickly, as such forms of lower urinary tract infections can travel up to kidneys, heart, and other areas, resulting in more severe complications.
Signs And Symptoms
- Lower and upper tract infections can cause one or more of the following symptoms: 1. Unusually frequent urination 2. An intense urge to urinate 3. Pain, discomfort or a burning sensation during urination 4. Pain, pressure or tenderness in the area of the bladder (midline, above or near the pubic area) 5. Urine that looks cloudy, or smells foul or unusually strong 6. Fever, with or withou…

- Symptoms of a UTI can vary. And while some individuals experience no signs at all, for most people, a UTI is uncomfortable and downright painful. Some common symptoms include:
Diagnosis
- Your doctor will ask you about your symptoms and whether you have had a urinary tract infection before. He or she also will ask you about your sexual history, including any history of sexually transmitted diseases for yourself and your partner, condom use, multiple partners, use of diaphragm and/or spermicides and whether you could be pregnant. Your doctor also will ask if y…
- You will need to give a thorough history of your dog’s health, including the onset and nature of the symptoms, to your veterinarian. He or she will then perform a complete physical examination as well a biochemistry profile, urinalysis, and complete blood count (CBC). Although the results of the CBC and biochemistry profile are often normal, urinalysis findings will provide valuable infor…
- UTIs and diabetes. Women with this condition have a higher risk of complications when they get a UTI than those without diabetes. The key is to diagnose and treat UTIs right away to avoid problems such as kidney infections.
- Common differential diagnoses for recurrent dysuria are listed in Table 3.12 Key steps in the diagnostic evaluation for recurrent UTIs include confirming the presence of a bacterial UTI, assessing the patient for risk factors and predisposing factors for complicated infection, and identifying a potentially causative organism. Figure 1 provides an algorithm for the assessment …
Cause
- Your urinary system includes your kidneys, ureters, bladder and urethra. All play a role in removing waste from your body. Your kidneys — a pair of bean-shaped organs located toward the back of your upper abdomen — filter waste from your blood and regulate the concentrations of many substances. Tubes called ureters carry urine from your kidneys to the bladder, where it's stored …
- While any part of the urinary tract can be impacted, most E. colicaused UTIs occur in the lower urinary tract, which includes the bladder (where urine is stored) and the urethra (the tube urine passes through to leave the body). A UTI that resides in the bladder is called cystitis; one that resides in the urethra is called urethritis. (5) One of the reasons that women are more prone to u…
- E. coli, Staphylococcus, and Proteus spp. account for more than half of all cases of bacterial infections of the lower urinary tract. Less common bacteria include Streptococcus, Klebsiella, Enterobacter, Pseudomonas, and Corynebacterium spp.
Prevention
- To help prevent urinary tract infections: 1. Drink several glasses of water each day. Fluids discourage the growth of bacteria by flushing out your urinary tract. Drinking cranberry juice may deter bacterial growth by decreasing the ability of bacteria to stick to the urethra. 2. Wipe from front to back. To prevent the spread of intestinal bacteria from the rectum to the urinary tract, w…
- Cranberry juice or tablets containing proanthocyanidin are often recommended to help reduce the risk of recurrent bladder infections for some women. However, recent studies suggest that it's less effective than previously thought. Some smaller studies demonstrated a small benefit, but larger studies found no significant benefit.As a home remedy, avoid cranberry juice if you're taki…
- You can help prevent UTIs by doing the following: 1. Urinate after sexual activity. 2. Stay well hydrated and urinate regularly. 3. Take showers instead of baths. 4. Minimize douching, sprays, or powders in the genital area. 5. Teach girls when potty training to wipe front to back.
- Patients with recurrent UTIs should be counseled about risk factors such as spermicide use, frequent sexual intercourse, and new sex partners, as well as about preventive measures. Antimicrobial prophylaxis has proved effective in reducing the risk of recurrent UTIs in women with two episodes of infection in the previous year. Continuous prophylaxis for six to 12 months …
Prognosis
- Once a woman has been cured of cystitis, she has a 20% chance of developing a second infection. After the second infection, she has a 30% risk of developing a third. If a woman has three or more episodes of cystitis within one year and the structure or anatomy of the urinary tract is normal, her doctor may prescribe a special antibiotic regimen to decrease the risk of future inf…
- Most urinary tract infections -- or UTIs -- are simple and usually easy to treat. When they're treated right away, they rarely lead to serious problems.
- Recurrent UTIs are symptomatic UTIs that follow resolution of an earlier episode, usually after appropriate treatment.1 Recurrent UTIs include relapses (i.e., symptomatic recurrent UTIs with the same organism following adequate therapy) and reinfection (i.e., recurrent UTIs with previously isolated bacteria after treatment and with a negative intervening urine culture, or a recurrent UTI …
- Lots of pregnant women tend to get UTIs in their 2nd or 3rd trimester. A lot of such cases are not serious and the symptoms gradually reduce after a few days. However; in many cases, a course of antibiotics might be essential. This can help treat the bladder infection lower back pain, provided one takes the medicines as recommended by the doctor. Even if the back pain on one side has e…
Risk Factors
- Some people are more likely than others to develop bladder infections or recurrent urinary tract infections. Women are one such group. A key reason is physical anatomy. Women have a shorter urethra, which cuts down on the distance bacteria must travel to reach the bladder.Women at greatest risk of UTIs include those who: 1. Are sexually active. Sexual intercourse can result in b…
- Some people are at higher risk of getting a UTI. UTIs are more common in women and girls because their urethras are shorter and closer to the rectum, which makes it easier for bacteria to enter the urinary tract.Other factors that can increase the risk of UTIs: 1. A previous UTI 2. Sexual activity, and especially a new sexual partner 3. Changes in the bacteria that live inside the vagin…
- Women are more likely than men to get a UTI. One reason for this is that women have a shorter urethra than men do, and it is closer to the anus. Both of these reasons explain why bacteria can reach the bladder more easily in women. Sexual activity also increases a woman's risk of UTI.The drop in estrogen levels that women experience after menopause also can make the urinary tract …
- Risk factors can either be general, usually affecting the immune system, or local, in which case normal emptying of the bladder is impaired. 1. Extremes of age: infants and old people have less resistance to infection 2. Diabetes, which increases the risk for urinary tract infections in several ways: 1. glucose in the urine is an excellent culture medium for organisms 2. diabetes impairs th…
Definition
- 1. Bacteriuria - this refers to the presence of bacteria in the urine. This may be symptomatic or asymptomatic. Asymptomatic bacteriuria should be confirmed by two consecutive urine samples. 2. Urinary tract infection (UTI) - this implies the presence of characteristic symptoms and significant bacteriuria from kidneys to bladder. Many laboratories regard 105 colony-forming uni…
- UTI is defined as the presence of at least 100,000 organisms per milliliter of urine in an asymptomatic patient, or as more than 100 organisms/mL of urine with accompanying pyuria (> 7 white blood cells [WBCs]/mL) in a symptomatic patient. A diagnosis of UTI should be supported by a positive culture for a uropathogen, particularly in patients with vague symptoms. [1]
Management
- Prognosis will ultimately depend on the diagnosis; however, most dogs require little more than antibiotics to resolve the infection. In cases of severe and complicated infections with obstructions, surgery may be required. Dietary changes may also be implemented to prevent future episodes of stone formation. Antibiotics should always be administered at the prescribe…
- Initiation of treatment depends on development of new symptoms (which may be subtle) in patients with chronic bacteriuria. Antibiotic selection should be based on community resistance patterns, and empiric initial treatment should be guided by likely organisms. The antibiotic regimen should be narrowed, when possible, to within 48 to 72 hours based on culture results. I…
- Some women may find it helpful to be made aware of the risk factors for recurrent infection. These include: 1. Use of spermicide 2. Frequent sexual intercourse 3. New sexual partnerCranberry juice has been traditionally advised as being helpful in the prevention and treatment of UTI; however, latest Cochrane reviews suggest the benefit is limited.A Cochrane re…
- Initial diagnosis of acute uncomplicated cystitis is typically based on patient medical history, taking into account past individual and family health issues, sexual activity, and current symptoms. Common indicators of acute cystitis include urinary urgency and frequency, pain when voiding (dysuria), lower abdominal discomfort, and cloudy or dark urine. The diagnosis of patien…
