Urinary Frequency: Differential Diagnosis & Clinical Approach | Chief Complaint Framework

How do you approach a patient with urinary frequency? In this Chief Complaint Framework video, we break down urinary frequency using a practical clinical reasoning approach—from the initial differential diagnosis to focused history, targeted examination, and diagnostic narrowing. Rather than memorizing a long list of causes, learn how to recognize the key patterns: Irritative symptoms → UTI, prostatitis, overactive bladder Obstructive symptoms → BPH, urethral stricture, urinary retention True polyuria → diabetes mellitus, diabetes insipidus, metabolic or medication-related causes Red flags → urinary retention, hematuria, infection, and neurologic symptoms We then apply the framework to a 62-year-old male with chronic progressive urinary frequency, nocturia, hesitancy, weak stream, and incomplete bladder emptying, ultimately narrowing the differential toward bladder outlet obstruction and BPH. High-yield takeaway: Urinary frequency ≠ polyuria. First determine whether the patient is voiding small amounts frequently or producing excessive urine. Then distinguish irritative, obstructive, and systemic/polyuric patterns to narrow your differential.
