Differential Diagnosis for a 43yo Male with Increased Urinary Frequency without Evidence of Infection
Single Most Likely Diagnosis
- Benign Prostatic Hyperplasia (BPH): This condition is common in men over 40 and can cause urinary frequency, urgency, and nocturia due to the enlargement of the prostate gland compressing the urethra.
Other Likely Diagnoses
- Overactive Bladder: A condition characterized by a sudden, intense urge to urinate, often accompanied by frequency and nocturia, which can be caused by various factors including neurological disorders, bladder outlet obstruction, or certain medications.
- Diabetes Mellitus: Uncontrolled diabetes can lead to hyperglycemia, causing an osmotic diuresis that results in increased urinary frequency.
- Prostatitis: Inflammation of the prostate gland, which can be non-infectious (e.g., chronic pelvic pain syndrome), leading to urinary frequency, pain, and discomfort.
Do Not Miss Diagnoses
- Urinary Tract Cancer: Although less common, cancers of the bladder, prostate, or kidneys can present with increased urinary frequency and must be ruled out to avoid delayed diagnosis and treatment.
- Neurogenic Bladder: A condition resulting from a neurological disorder (e.g., multiple sclerosis, spinal cord injury) affecting bladder control, leading to urinary frequency, urgency, and incontinence.
- Diabetic Ketoacidosis: A serious complication of diabetes that can cause increased urinary frequency due to the body's attempt to eliminate excess glucose and ketones.
Rare Diagnoses
- Interstitial Cystitis: A chronic condition causing bladder pressure, bladder pain, and sometimes pelvic pain, which can lead to increased urinary frequency and urgency.
- Bladder Outlet Obstruction: Other causes of obstruction, such as bladder stones or urethral stricture, which can cause urinary retention and frequency.
- Endocrine Disorders: Certain endocrine conditions like hyperthyroidism or hyperparathyroidism can lead to increased urinary frequency due to their effects on the body's metabolic rate and calcium levels.
