Narrowing of the urethra, often associated with prostate enlargement.

Narrowing of the urethra, often associated with prostate enlargement.

• A. Benign Prostatic Hypertrophy
• B. Urethrostenosis
• C. Nocturia
• D. Prostatism

Answer: (B)

This item focuses on a specific anatomical change: a narrowing of a tubular structure. Urethrostenosis is the term for narrowing of the urethral lumen. When the urethra is narrowed, urine flow is impeded, producing obstruction. The phrase “often associated with prostate enlargement” acknowledges that bladder outlet obstruction from an enlarged prostate can coexist with urethral changes, but the defining feature here is the lumen narrowing itself. Benign prostatic hypertrophy describes an enlarged prostate and its obstructive effect, not a narrowed urethral tube. Nocturia is simply the need to urinate at night, a symptom. Prostatism refers to the overall syndrome of symptoms caused by prostate enlargement, not the specific narrowing of the urethra. Therefore, urethrostenosis best fits the description.
