As the prostate enlarges, it puts pressure on the urethra similar to a clamp on a garden hose. With continued growth, the expanding prostate may constrict the urethra, causing symptoms such as difficulty starting urination or a weak urine stream.

Symptoms can include:

  • Sudden urge to urinate (urgency)
  • Difficulty starting and stopping your urine stream (hesitation)
  • The need to push or strain when urinating
  • Dribbling
  • Incomplete emptying (the sensation that the bladder is not empty after urinating)
  • Weak urine flow
  • Increased or decreased frequency of urination
  • Frequent nighttime urination (nocturia)
  • Burning or pain during urination
  • Incontinence
  • Blood in urine (hematuria)
These bothersome symptoms can have a profound effect on a man’s life, as men often change their lives to accommodate the need to urinate frequently. Treatment for the condition is necessary only if symptoms become intolerable. By age 80, 20% to 30% of men experience BPH symptoms severe enough to require treatment.
