What is microwave therapy?
Microwave therapy is a heat-based way of treating an enlarged prostate. A special catheter carries radiofrequency (microwave) energy into the prostate. The heat causes some of the obstructing prostate cells to die. Over the following weeks the prostate slowly shrinks back, which makes it easier to pass urine.
It is the most common of the heat-based BPH treatments. Dr Kooner performed the first microwave therapy for BPH in Australia.
How it is done
- You usually have sedation rather than a full general anaesthetic.
- A catheter with a microwave element is passed along the urethra into the bladder.
- The microwave energy heats the prostate while a cooling system protects the urethra.
- You may go home the same day, often with a catheter in place for a few days while the prostate settles.
Important things to know
- The benefit is not immediate. The prostate shrinks slowly over weeks. Most men notice a change in flow in the first few weeks but the full effect takes longer.
- You may need a catheter for a few days after the treatment while the prostate settles.
- Some men get burning when passing urine, urgency, or temporary blood in the urine. These usually settle.
- Microwave therapy does not relieve symptoms as completely as a TURP or laser in some patients. A small number of men need a further procedure later.
- Newer minimally invasive options like Rezum and iTind have largely overtaken microwave therapy in many practices, but it is still a useful option for some men, especially those who cannot have a general anaesthetic.
