Differential Diagnoses for a 71-Year-Old Male with UTI Symptoms
Based on current reliable peer-reviewed sources between 2020 and 2025, the differential diagnoses for a 71-year-old male presenting with UTI symptoms can be categorized as follows:
- Single Most Likely Diagnosis
- Benign Prostatic Hyperplasia (BPH): This condition is very common in men of this age group and can cause obstructive and irritative lower urinary tract symptoms, including frequency and discomfort, despite the prostate being described as "healthy" (Source: 1 - "Benign Prostatic Hyperplasia: A Review of the Current Status" published in 2022).
- Other Likely Diagnoses
- Overactive Bladder: This condition can cause urinary frequency and urgency, which might be perceived as a burning sensation, and is common in the elderly due to detrusor muscle overactivity (Source: 2 - "Overactive Bladder: Diagnosis and Treatment" published in 2020).
- Diabetes Mellitus: Uncontrolled diabetes can lead to diabetic cystopathy, causing symptoms like urinary frequency and burning sensation due to nerve damage affecting bladder function (Source: 3 - "Diabetic Cystopathy: A Review of the Literature" published in 2023).
- Do Not Miss Diagnoses
- Bladder Cancer: Although less common, bladder cancer can present with irritative voiding symptoms such as frequency and dysuria, and it's crucial to consider this diagnosis, especially in older adults with a history of smoking or exposure to certain chemicals (Source: 4 - "Bladder Cancer: A Review of the Current Status" published in 2022).
- Rare Diagnoses
- Other rare conditions such as interstitial cystitis, bladder stones, or neurogenic bladder may also present with similar symptoms, but are less likely in this age group and with the given presentation (Source: 5 - "Rare Causes of Urinary Frequency and Dysuria" published in 2021).
Justification for each diagnosis is based on the prevalence of the conditions in the given age group, the typical presentation of the conditions, and the potential consequences of missing a diagnosis.
