Symptoms will appear gradually over time. Prostate that has grown enough to create problems with urine flow may cause:

  • Incomplete emptying—a feeling that the bladder is not empty after urinating
  • Frequency—needing to urinate again less than 2 hours after urinating
  • Urgency—urge to urinate is very strong and hard to postpone
  • Nocturia—having to wake and get up out of bed to urinate

Note: Nighttime urination can also be a sign of other medical conditions. See your doctor if it persists.

Other common symptoms include:

  • Intermittency—urine flow stops and starts during urination
  • Hesitancy—having the urge to urinate, but need to wait until the flow actually starts
  • Weak stream—urine that trickles out rather than flows strongly
  • Straining—having to push or strain in order to urinate
  • Incontinence—leakage of urine, unable to stop flow of urine when needed
  • Hard time starting to urinate
  • Dribbling at end of urination
  • Deep discomfort in the lower belly

Backed-up urine may increase the risk of urinary tract infections (UTIs). BPH may increase the risk of frequent or chronic infections.

Elderly men with dementia may be at risk for a sudden complete blockage of urine flow. It can cause the bladder to stretch and cause lower abdomen to swell. This is the sign of an emergency.
