Rezūm BPH Treatment
Rezūm treatment for benign prostatic hyperplasia at a glance
- Rezūm is a minimally invasive treatment option for BPH (benign prostatic hyperplasia), an enlarged prostate gland that affects urine flow.
- Rezūm treatment uses controlled water vapor (steam) to remove the urethra blockage caused by BPH.
- Patients who undergo Rezūm experience fewer side effects compared with side effects seen in invasive surgical procedures.
What is Rezūm?
Rezūm therapy, also known as convective radiofrequency water vapor thermal therapy, is a minimally invasive treatment option for benign prostatic hyperplasia (BPH), which is an enlarged prostate gland. This enlargement blocks the urethra that carries urine from the bladder to the penis for expulsion. This enlargement can reduce the flow of urine from the bladder and sometimes block it completely.
As these symptoms increase, a man’s quality of life can be greatly affected. This can include urgency to urinate, getting up frequently at night to urinate and psychological distress.
Rezūm treatment releases thermal energy directly to the prostate gland to treat BPH by using water vapor (steam). When the steam contacts the prostate tissue, it converts to its liquid state and releases the thermal energy it had stored up. This thermal energy kills the cell membranes immediately, freeing up the blockage caused by BPH.
Rezūm therapy is minimally invasive, which means that no incisions are made during the procedure. This allows the patient to have Rezūm done in an outpatient clinic and experience a quicker recovery.

How is Rezūm BPH treatment done?
Rezūm is done in our office under local anesthesia, with or without the use of nitrous oxide, or laughing gas. The entire procedure takes just a few minutes to perform. During the procedure, a narrow sheath is inserted through the urethra. Once inserted, a thin needle is deployed from the sheath and into the prostate gland. Water vapor (steam) is then rapidly delivered to the prostate gland, typically within 8-10 seconds, causing the offensive cells to die.
Over time, the patient’s body will absorb the treated tissue through its natural healing process. As this process takes place, the symptoms of BPH are relieved. Typically, patients begin experiencing relief in as little as two weeks, with the maximum benefit occurring in one to three months.
Rezūm was approved by the Food and Drug Administration in 2015. Pacific Urology is one of six Rezūm centers of excellence in the world.
In a four-year clinical trial of Rezūm therapy, patients showed a sustained 51 percent reduction in symptom severity from the baseline at 24 months. Additionally, in the trial there was a surgical retreatment rate of only 4.4 percent.
The results also highlighted continued preservation of the patients’ sexual function with none of the patients reporting new problems with erectile dysfunction after the Rezūm therapy.
At Pacific Urology, we have treated more than 400 patients with the Rezūm therapy with excellent results and no major complications.
After Rezūm treatment for enlarged prostate
After treatment, patients will need a temporary catheter for drainage. Patients are given thorough instructions on how to remove the catheter at home. Patients can return to pre-procedural activity levels within a week of undergoing Rezūm therapy.
Since it is a minimally invasive procedure, patients who undergo Rezūm experience fewer side effects compared with those seen in invasive surgical procedures. However, as with any procedure, side effects may occur.
The most common side effects with Rezūm are:
- Mild pelvic discomfort.
- A small amount of blood in semen and urine.
- Mild urgency of and burning urination.
These side effects typically subside on their own within three weeks of the procedure. Discomfort during the short-term healing process can be relieved through a mild pain medication such as Tylenol, or a warm bath or heating pad.
Benefits and considerations of Rezūm BPH treatment
Rezūm therapy is chosen by many patients due to its minimally invasive nature. The procedure is performed in an office in minutes and patients can drive themselves home after the appointment.
Rezūm also provides the following benefits:
- Preserves sexual and urinary function.
- Alternative to BPH medications.
- Relieves symptoms quickly (typically within two weeks).
- Does not require general anesthesia.
- Allows patients to return to regular activities within a few days.

Who is the right candidate for Rezūm BPH treatment?
Patients should carefully consider each option before deciding on their BPH treatment plan. Rezūm is most successful in patients who meet the following criteria:
- Men with symptoms not severe enough for a surgical procedure such as a transurethral incision of the prostate (TUIP).
- Men who have tried other BPH treatment options that have failed.
- Men who are looking for an alternative to medication.
