Which symptom is NOT a typical feature of benign prostatic hyperplasia?

• A. Dysuria
• B. Nocturia
• C. Polyuria
• D. Hesitancy

Answer: (C)

Benign prostatic hyperplasia causes urinary symptoms because the enlarged prostate narrows the outlet and affects bladder function. The typical picture includes hesitancy, a weak or intermittent stream, a feeling of incomplete emptying, dribbling, and nocturia. Irritative symptoms like frequency and urgency can also occur. Polyuria—producing large volumes of urine—does not result from prostatic enlargement. It points to other conditions such as diabetes mellitus, diabetes insipidus, or diuretic use. Because excessive urine production is not a consequence of bladder outlet obstruction from BPH, it is not a typical feature of this condition. Dysuria can appear with irritation or infection but is less central to the BPH pattern compared with hesitancy, weak flow, and nocturia.
