Urinary tract infections (UTIs) are common, especially among women, though men, children, and the elderly can also experience them. These infections occur when harmful bacteria or fungi enter the urinary system, which includes the kidneys, ureters, bladder, and urethra. While UTIs are usually easily treated, they can be painful and may lead to complications if left untreated. Understanding the causes, symptoms, and available treatments for UTIs is essential for effective prevention and management.
What Causes UTIs?
The majority of UTIs are caused by bacteria, most commonly Escherichia coli (E. coli), which normally lives in the intestines. The urinary tract is typically sterile, but when bacteria from the digestive tract or skin enter the urethra, they can multiply and cause an infection. Factors that contribute to the likelihood of bacteria reaching the urinary tract include poor hygiene, sexual activity, holding urine for extended periods, and the use of certain types of contraceptives, such as diaphragms or spermicides.
Women are more prone to UTIs than men due to the shorter length of the female urethra, which allows bacteria to reach the bladder more easily. Additionally, hormonal changes during pregnancy, menopause, and other life stages may further increase the risk. Men, on the other hand, may develop UTIs due to prostate problems, particularly in older age. People with conditions like diabetes or weakened immune systems are also at a higher risk of developing UTIs.
Urology Partners of North Texas emphasizes that UTIs can vary in severity, and while most are limited to the lower urinary tract (bladder and urethra), more severe infections can spread to the kidneys, requiring prompt medical attention. If you experience symptoms of a UTI—such as a frequent urge to urinate, burning sensation during urination, cloudy or strong-smelling urine, or pain in the lower abdomen—seeking care is essential to avoid complications. Visit your healthcare provider, or reach out to Urology Partners of North Texas for expert advice on urinary health.
Types of UTIs
There are different types of UTIs based on the location of the infection within the urinary tract:
- Cystitis: A bladder infection caused when bacteria enter the bladder and multiply. This is the most common type of UTI, particularly in women.
- Urethritis: An infection of the urethra, which is the tube that carries urine from the bladder to be expelled from the body. This infection is more likely to occur in sexually active individuals and can sometimes be mistaken for a sexually transmitted infection (STI).
- Pyelonephritis: A kidney infection that can develop when bacteria travel up from the bladder through the ureters to the kidneys. This type of UTI is more serious and can cause back pain, fever, nausea, and vomiting.
Symptoms of UTIs
The symptoms of UTIs vary depending on which part of the urinary tract is infected, but some of the most common include:
- A strong, persistent urge to urinate
- A burning sensation during urination
- Passing frequent, small amounts of urine
- Cloudy, dark, or bloody urine
- Foul-smelling urine
- Pain or pressure in the lower abdomen or pelvis
- In the case of a kidney infection, fever, chills, nausea, and pain in the back or sides may occur.
How UTIs are Diagnosed
If you suspect a UTI, your healthcare provider will perform a urine test to detect bacteria, white blood cells, or red blood cells in your urine. This test can help confirm the diagnosis and guide the treatment plan. Sometimes, a urine culture is done to identify the specific type of bacteria causing the infection, which helps select the most effective antibiotic. In recurrent or complicated UTIs, additional tests such as imaging (ultrasound, CT scan) or cystoscopy may be recommended to assess the urinary tract for abnormalities or obstructions.

Treatment Options for UTIs
The treatment for UTIs generally involves antibiotics to eliminate the bacterial infection. The type and duration of antibiotics depend on the severity of the infection and whether it’s a first-time occurrence or a recurrent issue. Common antibiotics prescribed for UTIs include trimethoprim/sulfamethoxazole, nitrofurantoin, cephalexin, and amoxicillin-clavulanate.
For most people, symptoms start to improve within a few days of starting antibiotics, though it’s important to complete the entire course of medication as prescribed to fully eradicate the infection and prevent a recurrence. In cases of more severe kidney infections, hospitalization may be required for intravenous antibiotics and other supportive care.

Preventing UTIs
Preventing UTIs involves adopting certain lifestyle and hygiene practices. Here are some tips to reduce your risk:
- Drink plenty of water: Staying well-hydrated helps flush out bacteria from your urinary tract.
- Urinate frequently: Avoid holding urine for long periods, as this can allow bacteria to multiply.
- Wipe from front to back: After using the restroom, this helps prevent bacteria from the anus from spreading to the urethra.
- Urinate after sexual activity: This helps eliminate bacteria introduced during intercourse.
- Avoid irritating products: Scented hygiene products, douches, or harsh soaps can irritate the urethra and increase the risk of infection.
Recurrent UTIs
Some individuals, particularly women, experience recurrent UTIs, defined as two or more infections in six months or three or more within a year. In such cases, your healthcare provider may recommend longer-term antibiotic therapy, vaginal estrogen therapy for postmenopausal women, or other preventive measures like taking a single dose of antibiotics after sexual activity. Addressing any underlying health conditions, such as kidney stones or urinary tract obstructions, is also important in managing recurrent infections.
When to Seek Medical Attention
Most UTIs are uncomplicated and resolve with treatment. However, if symptoms persist despite treatment, or if you experience signs of a kidney infection, such as high fever, chills, or back pain, seek medical attention promptly. Delayed treatment of a UTI can lead to complications, including permanent kidney damage or sepsis, a life-threatening condition.
If you are experiencing frequent UTIs, it may be helpful to consult a urology specialist to explore any underlying issues that could be contributing to the infections.
