How does hypertrophy of the prostate affect the bladder?

• A. Eliminates the urge to void
• B. Interfere with flow of urine
• C. Increases bladder capacity
• D. Reduces kidney filtration

Answer: (B)

Prostate enlargement narrows the urethral passage, creating bladder outlet obstruction. The bladder must work harder to push urine through the narrowed channel, so urine flow is impeded. That’s why the primary effect on the bladder is interference with urine flow. Over time, the detrusor muscle may hypertrophy to overcome the obstruction, and there may be symptoms like a weak stream or incomplete emptying. This doesn’t eliminate the urge, nor does it increase bladder capacity; long-term obstruction can affect kidneys, but the immediate consequence described here is the disrupted flow.
