Five Misconceptions About Enlarged Prostate

Enlarged prostate, also known as benign prostatic hyperplasia (BPH), is a condition in which the prostate grows and presses on the urethra. This can obstruct the flow of urine and can disrupt a man’s life by causing uncomfortable symptoms, like having a weak stream or difficulty starting or stopping urination.[1] BPH is a common condition in older men, yet there are many misconceptions about treatment options, their side effects and what it means to live with BPH.[2]

Here are five common myths about BPH.

1. Only older men get BPH

While it’s true that up to 90% of men develop BPH by age 85, younger men can develop the condition too. Did you know 50% of men by age 60 will develop BPH?2 Some data suggest that approximately 1 in 12 men between the ages of 41 and 50 can also suffer from BPH. Men with BPH may experience waking up throughout the night to urinate or the feeling that the bladder is not empty, even after relieving themselves.[3]

2. BPH is connected to prostate cancer

BPH and prostate cancer may present similar symptoms, but having BPH does not increase the risk of developing prostate cancer.[4] However, since they do have similar symptoms, such as a frequent urge to urinate or a weak urinary stream, it is important to talk to a doctor for an accurate diagnosis.4

3. If BPH symptoms aren’t severe, treatment isn’t needed

When BPH symptoms aren’t severe, health care providers may recommend a “watch and wait” approach, which may include behavior modifications and therapies.[5] Examples include:

  • Avoiding fluids prior to bedtime or before going out
  • Reducing consumption of diuretics such as caffeine or alcohol
  • Pelvic floor muscle training

If the “watch and wait” approach isn’t effective, minimally invasive treatment options may provide relief. It is important to speak with a healthcare provider to determine the best course of action to help maintain quality of life. By delaying treatment, men, particularly those who are older, may experience worsening BPH symptoms.[6]

4. Most treatment options for moderate or severe BPH require significant recovery time

For moderate or severe forms of BPH, treatment options beyond lifestyle adjustments may be recommended. For patients who want to avoid the potential side effects that come with some surgical procedures, minimally invasive procedures, such as Rezūm™ Water Vapor Therapy, may be an option. Rezūm Therapy uses the energy stored in water vapor to reduce the size of the prostate and provide lasting relief. It works by releasing water vapor into the excess prostate tissue that’s causing bothersome urinary symptoms.[7] Over time, the body’s natural healing response absorbs the treated tissue, shrinking the prostate.[8] Most patients who receive Rezūm Therapy return to regular activities within a few days after treatment and see symptom improvement within two weeks.[9]

5. Multiple treatments are required to treat BPH

Treatment options for BPH can include medication to manage symptoms, minimally invasive procedures and surgery.[10] While some patients require multiple treatments, others may not. A clinical study found that patients treated with Rezūm Therapy had sustained symptom relief and preserved their sexual function out to five years — with only 4.4% of study participants requiring another surgical treatment for BPH symptoms.7

All treatments have inherent and associated risks. The Rezūm System is intended to relieve symptoms, obstructions, and reduce prostate tissue associated with BPH. It is indicated for men ≥ 50 years of age with a prostate volume 30cm3 ≤ 80cm3. The Rezūm System is also indicated for treatment of prostate with hyperplasia of the central zone and/or a median lobe. Potential risks include but are not limited to painful urination (dysuria), blood in the urine (hematuria), blood in the semen (hematospermia), decrease in ejaculatory volume, suspected urinary tract infection (UTI), and urinary frequency, retention or urgency. You should talk with your doctor about benefits and risks before moving forward with any treatment option.
