Benign Prostatic Hyperplasia (BPH): This condition is common in men of this age group and can cause urinary retention due to the enlargement of the prostate gland, which compresses the urethra.

Urinary Tract Infection (UTI): A UTI can cause irritation and inflammation of the urinary tract, leading to symptoms of urinary retention.
Prostatitis: Inflammation of the prostate gland can cause urinary symptoms, including retention.
Neurogenic Bladder: Conditions affecting the nerves that control the bladder can lead to urinary retention, although this might be less common in the absence of other neurological symptoms.

Prostate Cancer: Although less likely than BPH, prostate cancer can cause urinary retention and must be considered, especially if there are other symptoms like weight loss or bone pain.
Spinal Cord Injury or Compression: Any condition that affects the spinal cord, such as a herniated disk, tumor, or injury, can lead to neurogenic bladder and urinary retention. This is critical to identify due to its potential for serious neurological consequences.
Urethral Stricture: A narrowing of the urethra can cause obstructive urinary symptoms, including retention. This condition can result from trauma, infection, or other causes.

Bladder Neck Contracture: A rare condition where the bladder neck narrows, causing obstructive urinary symptoms.
Urethral Cancer: A rare type of cancer that can cause urinary retention among other symptoms.
Phimosis: A condition where the foreskin cannot be fully retracted over the glans penis, which can lead to urinary retention in uncircumcised males, although this is more common in younger men.
