Recognizing the symptoms of a UTI is essential for timely and effective treatment. While symptoms can vary based on age, sex, and underlying conditions, common indicators include dysuria, urinary frequency, urgency, hematuria, and changes in urine appearance. Accurate diagnosis often requires a combination of symptom assessment and urine analysis. Understanding these symptoms can help healthcare providers make informed decisions and improve patient outcomes.
Urinary Tract Infections (UTIs) are among the most common bacterial infections affecting individuals of all ages and sexes. Understanding the symptoms associated with UTIs is crucial for prompt diagnosis and effective treatment. This article provides an overview of the common symptoms of UTIs based on recent research findings.
Common Symptoms in Children
In children, UTIs can present with a variety of symptoms that often differ based on age. During infancy, the symptoms are generally non-specific, with unexplained fever being the most common indicator. As children grow older, the symptoms become more specific. After the age of two, symptoms of pyelonephritis (a type of UTI affecting the kidneys) include fever, chills, rigor, flank pain, and costovertebral angle tenderness. Lower urinary tract symptoms in children include suprapubic pain, dysuria (painful urination), urinary frequency, urgency, cloudy urine, malodorous urine, and suprapubic tenderness1.
Symptoms in Women
UTIs are particularly prevalent among women, and the symptoms can vary widely. Common symptoms include dysuria, urinary frequency, urgency, hematuria (blood in urine), and nocturia (frequent urination at night). The presence of dysuria and frequency without vaginal discharge or irritation significantly increases the likelihood of a UTI2 4. Additionally, hematuria has been identified as having the highest diagnostic utility, especially when combined with a positive dipstick result for nitrites2.
Symptoms in Urogynecologic Patients
In women seeking urogynecologic care, the presence of dysuria is a significant indicator of a UTI. Dysuria is often accompanied by higher severity and bother scores for other urinary symptoms such as frequency and urgency. This makes dysuria a more reliable symptom for diagnosing UTIs in this population5.
Symptoms in Patients with Neurogenic Bladder
Patients with neurogenic bladder, such as those with spinal cord injuries or multiple sclerosis, often report non-specific symptoms like changes in urine appearance (cloudy or smelly urine) and altered mental status (brain fog). These symptoms can lead to inappropriate UTI diagnoses if not carefully evaluated. Dysuria and pelvic pain are also frequently reported in this group7.
Diagnostic Considerations
The diagnosis of a UTI is often based on a combination of symptoms and positive urine analysis or culture. For women under 65, the National Institute for Health and Care Excellence (NICE) recommends diagnosing a UTI if they present with two or more key symptoms such as dysuria, new nocturia, and cloudy urine6. However, it is important to exclude other possible causes of urinary symptoms, such as vaginal and urethral conditions, and to consider warning signs of other conditions like sepsis and cancer6.
