He has to urinate every 12 hours during the day and wakes up at least 23 times at night to urinate. He also reports that over the last 2 months, he has difficulty initiating micturition and the urinary stream is weak, with prolonged terminal dribbling. His pulse is 72min, and blood pressure is 158105 mm Hg. Rectal exam shows a smooth, symmetrically enlarged prostate without any tenderness or irregularities. Prostate-specific antigen is within the reference range and urinalysis shows no abnormalities. A postvoid ultrasound shows a residual bladder volume of 110 mL. Which of the following is the most appropriate next step in management?? A: Bladder catheterization, B: Transurethral resection of the prostate, C: Terazosin therapy, D: Finasteride therapy, E: Cystoscopy,  <response>: This is a question about benign prostatic hyperplasia BPH. The patient is a 59-year-old man with lower urinary tract symptoms frequent urination, weak stream, terminal dribbling and incomplete bladder emptying, as evidenced by the post-void residual volume. The enlarged prostate on rectal exam and elevated PSA are consistent with BPH. The question asks for the most appropriate next step in management. Choice A, bladder catheterization, is incorrect because it does not treat the underlying cause and poses infection risk. Choice B, transurethral resection of the prostate TURP, is too aggressive as initial therapy. Choices D and E, finasteride and cystoscopy, are not indicated at this stage. Choice C, terazosin therapy, is correct. An alpha blocker like terazosin is the appropriate first-line medical therapy for symptomatic BPH. It works by relaxing smooth muscle in the prostate and bladder neck to improve urine flow and symptoms.C: Terazosin therapy
