  • The cause of BPH is unknown.
  • Male sex hormones play a role.
  • Frequent or urgent need to urinate; delayed, weak, or interrupted urine stream; dribbling.
  • Pain upon urination.
  • Urge to urinate several times a night.
  • Blood in the urine.
  • Patient history and physical examination, which includes a digital rectal examination (DRE). In DRE the doctor inserts a gloved finger into the rectum and presses on the prostate gland to check for enlargement.
  • Tests to measure the rate of urine flow.
  • Urine tests and cultures.
  • Measurement of retained urine within the bladder.
  • Treatment may be unnecessary for mild symptoms.
  • Excess alcohol or fluid intake, especially at night, should be avoided.
  • Your doctor may prescribe medication such as Proscar (finasteride) to shrink the prostate or drugs that relax smooth muscle tone in the prostate (alpha-blockers).
  • Heat treatment (the application of heat to prostate tissue) can be used to alleviate symptoms of BPH. An advantage of this approach is that it can be administered on an outpatient basis using minimally invasive microwave or radio-frequency energy.
  • Removal of excess tissue from an enlarged prostate via transurethral resection of the prostate (TURP) is the most common surgical treatment. A thin, lighted viewing tube is passed through the penis into the urethra. A minuscule cutting tool at the end of the tube is used to excise prostate tissue that is pressing upon the urethra.
  • Surgical removal of obstructing prostate tissue via an abdominal incision may be necessary when the prostate is unusually large.
  • There is as yet no way to prevent BPH
