A patient with benign prostatic hypertrophy (BPH) presents with reduced urinary stream and dribbling. Which type of urinary incontinence is most likely?

• A. Overflow UI
• B. Stress UI
• C. Functional UI
• D. Reflex UI

Answer: (A)

The situation describes overflow incontinence, which happens when the bladder cannot empty effectively due to obstruction—in this case, from benign prostatic hypertrophy (enlarged prostate). The reduced urine stream signals outlet resistance, and the dribbling reflects continuous leakage as the bladder remains overfilled and pressure leaks past the sphincter. Over time, the detrusor muscle may struggle to complete voiding, so urine accumulates and leaks gradually, which is the hallmark of overflow incontinence. Stress incontinence would involve leakage with physical effort like coughing or lifting, not just a weak stream with dribbling. Functional incontinence comes from an inability to reach the toilet in time, usually due to mobility or cognitive issues. Reflex (neurogenic) incontinence involves abnormal nerve signaling to the bladder, leading to involuntary leakage independent of obstruction.
