What is an Enlarged Prostate?

Enlarged prostate lift icon


The prostate is a muscular gland next to the bladder that surrounds part of the urethra, which is the tube that carries urine and sperm out of the body. It is responsible for the production of semen. When healthy, the prostate is roughly the size of a walnut. However, as men age, many develop an enlarged prostate. Due to its positioning near the bladder and around the urethra, an enlarged prostate can restrict urine flow or cause other significant urinary symptoms.

Diabetic Neuropathy Pain icon


Prostate enlargement can be caused by prostate cancer, but it’s much more common for an enlarged prostate to be a non-cancerous condition called benign prostatic hyperplasia (BPH). The exact cause of BPH is yet to be determined, but we know for certain that the condition is closely tied to aging. Benign prostatic hyperplasia affects the majority of men as they get older, with some studies finding that as many as 90% of men have BPH by age 85.

Enlarged Prostate Symptoms

Urinary symptoms can be indicative of prostate problems. For many men, enlarged prostate symptoms can cause a great deal of discomfort and seriously hinder everyday life. Fortunately, the symptoms of an enlarged prostate are often treatable with medications and/or interventional procedures, and men seeking treatment for BPH have quite a few options to choose from.

Common Enlarged Prostate Symptoms

  • Frequent need to pee
  • Urgency (sudden, overwhelming need to urinate)
  • Peeing more often at night (nocturia)
  • Difficulty starting to pee
  • Weak urine stream, or a stream that stops and starts
  • Dribbling at the end of urination
  • Not being able to fully empty bladder
  • Feeling like you still have to pee after peeing


Less Common Enlarged Prostate Symptoms

  • Urinary tract infection (UTI)
  • Not being able to pee
  • Blood in the urine

Enlarged Prostate Diagnosis

Symptoms of an enlarged prostate are relatively straightforward to identify, but extensive testing may be required to confirm for certain that your enlarged prostate symptoms are indeed caused by BPH and not prostate cancer or some other urologic condition.

Enlarged prostate medical history icon

Medical History

Your physician will ask you a series of questions about your experiences, symptoms, and medical history.

Enlarged prostate digital rectal exam icon

Enlarged prostate cystoscopy icon


Allows your physician to visualize inside the urethra and the bladder.

Enlarged Prostate Treatment

BPH treatment focuses on symptom relief. Many treatments are available for BPH, ranging from oral medications to minimally invasive procedures and invasive surgeries. The ideal treatment for you will, in part, be determined by your prostate and bladder anatomy, your age, your medical history, and your treatment preferences.

Enlarged prostate alpha blockers icon

Alpha Blockers


Alpha blockers work by relaxing the smooth muscle of the bladder neck and the prostate, making it easier to pee.

Enlarged prostate 5ARIs icon



5 alpha reductase inhibitors (5ARIs) shrink the prostate by inhibiting the hormone changes that cause the prostate to grow.

Enlarged prostate tadalafil icon



Tadalafil (Cialis) is an erectile dysfunction medication that may also be prescribed to treat prostate enlargement.

Enlarged prostate prostatic artery embolization icon

Prostatic Artery Embolization

(Minimally Invasive Procedure)

Prostatic artery embolization (PAE) works by embolizing (blocking) the blood vessels that supply the prostate. This is accomplished by threading a catheter to the prostate artery through a tiny puncture in your arm or in your leg using real-time imaging. Once in position, microscopic beads are injected through the catheter into the prostate artery, blocking blood flow to the prostate. Following the procedure, the prostate shrinks, relieving BPH symptoms.

Patients often choose prostate artery embolization because it is less invasive than traditional surgery and less traumatic than other specialized interventions that target the prostate directly. Compared to other therapies, PAE provides minimal risk of sexual side effects, low risk of urinary incontinence, no hospital stay, quick recovery, and minimal downtime following the procedure.

Enlarged prostate vapor ablation icon
