Many men initially assume Benign Prostatic Hyperplasia (BPH) is a natural consequence of getting older (e.g. waking up during the night to urinate or needing the bathroom more frequently). However, in many cases, BPH progressively becomes far more disruptive than anticipated. Constant urination can result in serious sleep deprivation, leaving patients fatigued throughout the day. Some men begin avoiding travel, meetings, or social gatherings because they worry about not finding a restroom quickly enough. Others face a sudden "crisis moment" such as acute urinary retention requiring emergency catheterisation. Medication may provide relief initially, but prolonged use often brings medication fatigue and anxieties about sexual side effects. Meanwhile, conventional prostate surgery can raise concerns about complications affecting sexual function. For many patients seeking a contemporary, effective, and less invasive solution, Rezum therapy is the answer, and BNH Hospital in Bangkok is a preferred choice. To help you better understand this treatment, here are 5 commonly asked questions about Rezum therapy at BNH Hospital. 1. What is Rezum therapy?Rezum therapy is a minimally invasive treatment that utilises natural water vapour (steam) to reduce enlarged prostate tissue. The targeted steam releases energy to eliminate excess prostate cells that cause urinary blockage. Over time, the body naturally absorbs the treated tissue, enabling the prostate to open the urinary channel and alleviate symptoms. 2. Why is Rezum therapy preferred over other treatment options?Many men with BPH want a simple and straightforward treatment that addresses urinary symptoms. Rezum water vapour therapy delivers an effective, safe, and minimally invasive alternative to traditional surgery. One primary reason patients select Rezum is its ability to preserve sexual function. Unlike certain conventional prostate surgeries that may trigger retrograde ejaculation, Rezum is designed to minimise these risks, enabling men to improve urinary symptoms whilst maintaining sexual health. Rezum can also help patients reduce or eliminate long-term BPH medications. Drugs such as alpha-blockers or 5-alpha reductase inhibitors typically need to be taken for years and may produce side effects like dizziness, low blood pressure, or reduced libido. Another advantage is its minimally invasive procedure. Rather than cutting or removing prostate tissue, it employs targeted water vapour delivered through the natural urinary channel to reduce the enlarged prostate, lowering the risks associated with traditional surgery. The procedure is also quick and convenient, typically completed in a brief outpatient visit with a relatively swift recovery. Many patients return home the same day and resume normal activities soon afterwards. Most importantly, Rezum delivers lasting relief from common BPH symptoms, such as frequent urination, weak urine stream, urgency, and nighttime urination. For many men, it represents an effective and modern solution for managing an enlarged prostate with minimal disruption to daily life. 3. Who performs Rezum treatment at BNH Hospital?Rezum therapy at BNH Hospital is performed by Dr Suntchai Wirotsaengthong, a leading urologist specialising in minimally invasive prostate treatments. He is recognised as a Centre of Excellence (COE) physician for Rezum therapy and leads the first Rezum Centre of Education in ASEAN. Dr Suntchai’s extensive expertise not only attracts patients but also mentors physicians across the region, helping them master the procedure firsthand. 4.

Through March 2026, patients can access a special rate of 185,000 baht, saving 35,000 baht on this advanced treatment. 5. How can patients get started with Rezum treatment at BNH Hospital?Rezum is not a one-size-fits-all treatment and doesn't deliver immediate results. Each patient's symptoms and overall health vary, so it's always important to first discuss your situation with a specialist. During consultation, specialists will determine whether Rezum is appropriate for your case and explain realistic expectations for results.
