A 65-year-old male presents to the clinic with complaints of difficulty urinating for the past 6 months. He reports a weak urine stream, frequent trips to the bathroom, especially at night, and a feeling of incomplete bladder emptying. Over the last few weeks, the symptoms have worsened, causing him significant discomfort. He denies any blood in the urine or pain during urination.

On physical examination, his abdomen is soft but shows mild suprapubic tenderness. A digital rectal exam reveals an enlarged, smooth, and firm prostate. Laboratory tests, including a PSA (prostate-specific antigen) level, are within normal limits for his age. A post-void residual bladder scan shows retained urine, indicating incomplete bladder emptying.

The diagnosis of benign prostatic hyperplasia (BPH) is made based on his clinical symptoms and physical findings. The patient is advised on treatment options, including lifestyle changes, medications (alpha-blockers), and the potential for future surgical intervention if symptoms persist or worsen.
