What are the initial diagnostic steps for urinary incontinence?

• A. Focused history and physical examination; urinalysis and post-void residual; renal US, creatinine, and BUN if renal pathology suspected
• B. Urodynamic testing as first test
• C. MRI pelvis is the initial test
• D. Treatment with antimuscarinics before evaluation

Answer: (A)

When evaluating urinary incontinence, start with noninvasive, broad screening to classify the type and rule out reversible or serious issues. Begin with a focused history and physical to understand the pattern of leakage, triggers (such as coughing or sneezing), daytime and nighttime symptoms, medications, fluid intake, and pelvic floor status, along with a quick neurologic review. A urinalysis is essential to exclude infection, blood, or abnormal glucose that could explain the symptoms. Measuring post-void residual helps determine if incomplete bladder emptying contributes, suggesting overflow physiology or obstruction. If renal pathology is suspected from history, exam, or urinalysis results, proceed with renal ultrasound and basic kidney function tests (creatinine and BUN). Urodynamic testing or pelvic MRI aren’t first-line; they’re used when the initial evaluation doesn’t clarify the cause or before surgical planning.
