Which symptom indicates possible bladder outlet obstruction in men with BPH?

• A. Urinary Frequency Only
• B. Nocturia With Normal Stream
• C. Painful Urination
• D. Weak Urinary Stream With Hesitancy and Straining

Answer: (D)

When bladder outlet obstruction is present from enlarged prostate, the水 flow is directly impeded, so initiating and maintaining voiding becomes difficult. This shows up as a weak urinary stream and the need to strain to start and sustain urination—often with hesitancy. These signs point to an actual physical blockage at the outlet, rather than just irritation or infection symptoms.

Other options aren’t as specific for obstruction: urinary frequency alone or nocturia with a normal stream can occur for many reasons and don’t confirm blocked flow, and painful urination points more toward infection or inflammation rather than a mechanical blockage.
