Rezum Water Vapour Therapy is a minimally invasive procedure designed to treat benign prostatic hyperplasia (BPH), a common condition where the prostate gland enlarges and compresses the urethra, causing urinary symptoms.
This therapy uses the natural energy of water vapour (steam) to target and reduce the excess prostate tissue responsible for these symptoms. Unlike traditional surgical options, Rezum therapy offers a minimally invasive alternative that eliminates the need for general anaesthesia, hospital stays, or long recovery periods. The approach is particularly valued for its ability to relieve symptoms without compromising critical functions such as sexual health and urinary continence.
By addressing the underlying cause of BPH symptoms — excess prostate tissue — Rezum therapy improves quality of life for patients and enables them to regain normal urinary function. The treatment is ideal for men seeking a modern alternative to long-term medication or invasive surgeries such as transurethral resection of the prostate (TURP). Its effectiveness, convenience, and safety make it a preferred option for managing BPH.
Rezum therapy is performed as an outpatient procedure, typically under local or mild sedation. A specialised device is used to deliver small, precise doses of water vapour directly into the prostate tissue through the urethra. Guided by ultrasound imaging, the urologist ensures accurate placement of the device, which injects steam into the targeted areas of the prostate. Each injection lasts about nine seconds, during which the steam disperses thermal energy into the tissue. This heat causes the prostate cells to break down and die.
After the procedure, the body’s natural healing processes begin. The treated cells are gradually reabsorbed, leading to a reduction in the size of the prostate over the course of several weeks to months. Most patients begin to notice symptom improvement within two weeks, with full benefits typically realised within three months.
Rezum therapy is precise, targeting only the areas causing symptoms, while leaving surrounding tissues and structures unharmed. It eliminates the need for incisions, and reduces the risk of infection or significant complications. In some cases, a temporary urinary catheter may be placed to aid bladder emptying during the initial healing phase. Patients generally experience minimal downtime and can resume normal activities shortly after the procedure.
Rezum Water Vapour Therapy offers a range of advantages, which makes it an appealing choice for men seeking effective treatment for benign prostatic hyperplasia (BPH) without the need for invasive surgery or long-term medication. Here are the key benefits:
These benefits make Rezum therapy a modern and effective solution for managing BPH, improving quality of life with minimal disruption.
At Allen Sim Urology, we utilise Rezum Water Vapour Therapy to provide effective relief for men experiencing urinary issues caused by benign prostatic hyperplasia (BPH). This treatment is tailored to address the following conditions:
Like any medical procedure, Rezum Water Vapour Therapy may have some side effects, but they are generally mild and temporary. Common side effects include:
These side effects are part of the body’s natural response to the treatment and usually diminish as the healing process progresses. At Allen Sim Urology, we provide detailed aftercare instructions and support to help manage any temporary discomfort and ensure a smooth recovery.
Like any medical procedure, Rezum Water Vapour Therapy may have some side effects, but they are generally mild and temporary. Common side effects include:
mild burning or stinging sensations that usually subside within a few days to weeks.
this is a normal part of the healing process and typically resolves on its own.
increased urinary frequency or urgency may occur initially but improves as the prostate heals.
in rare cases, difficulty urinating may require a temporary urinary catheter.
These side effects are part of the body’s natural response to the treatment and usually diminish as the healing process progresses. At Allen Sim Urology, we provide detailed aftercare instructions and support to help manage any temporary discomfort and ensure a smooth recovery.
At Allen Sim Urology, during your initial consultation, we will thoroughly evaluate your condition, discuss your symptoms, and explain how the therapy works to help you make an informed decision.
On the day of the procedure, you will be prepared with either local anaesthesia or mild sedation to ensure comfort. The therapy itself is minimally invasive and takes less than an hour to complete. A specialised device is used to deliver targeted steam injections into the prostate tissue, breaking down the cells causing your symptoms. Once the procedure is complete, you may require a temporary urinary catheter for a few days to assist with bladder emptying during the initial healing phase.
Following the procedure, our team will provide clear post-operative care instructions according to your needs. It’s common to experience mild discomfort, blood in the urine, or increased urinary frequency for a few days to weeks, but these symptoms typically resolve as your body heals. We recommend avoiding heavy lifting and strenuous activity for a short period and attending follow-up appointments to monitor your progress.
Most patients begin to notice improvements in their urinary symptoms, such as better flow and reduced frequency, within two weeks. Maximum results are usually achieved within three months as the body gradually absorbs the treated tissue. Rezum therapy offers long-term relief, with many patients experiencing sustained benefits for years.
At Allen Sim Urology, we also emphasise aftercare to ensure you achieve optimal outcomes. Our team is always available to address your concerns and provide guidance as you recover, helping you regain control of your life with improved urinary function and comfort.
Rezum Water Vapour Therapy typically requires only one session to effectively treat benign prostatic hyperplasia (BPH). The procedure is designed to target and reduce excess prostate tissue in a single treatment, with results gradually improving over the following weeks to months. Most patients do not require additional sessions, but your urologist will monitor your progress during follow-up appointments to ensure optimal outcomes.
If you are experiencing urinary symptoms caused by an enlarged prostate, schedule a consultation with us to explore how Rezum Water Vapour Therapy can provide long term relief and improve your quality of life.
Clinical studies have demonstrated sustained symptom improvement for up to five years following a single treatment. Individual results may vary.
Some patients may require a temporary urinary catheter for a few days post-procedure to aid in bladder emptying during the initial healing phase. Your urologist will provide guidance based on your specific situation.
Most patients can resume normal activities within a few days after the procedure. Your doctor will offer personalised recommendations based on your recovery progress.
Rezum Therapy is typically performed under local anesthesia or oral sedation, which minimises discomfort during the procedure. Most patients report only minor discomfort, if any.
