Benign prostate enlargement – Rezum is a minimally invasive transurethral water vapour therapy for benign prostatic enlargement which uses thermal energy for treatment. The short-term results show it to have good outcomes with a potential for outpatient-based treatment preserving sexual function.

Benign prostatic hyperplasia (BPH) with associated lower urinary tract symptoms is a common medical condition in males over 50 years of age and is not usually a serious threat to health. In the United Kingdom the number of men with symptomatic BPH who require a surgical treatment is projected at 25,000 annual incidences.

Benign prostate enlargement – Rezum is suitable for the majority of men presenting with urinary symptoms due to an enlarged prostate. It is carried out as a day procedure and is an excellent choice for those who wish to retain their sexual function.

How is this treatment performed?

The REZUM Therapy system consists of a portable radio-frequency generator and delivery device to heat up a controlled amount of water in the Delivery Device outside of the body, converting the water into vapour or steam which is delivered into the prostate tissue that causes BPH.

Radio frequency energy from the generator is applied to an inductive coil in the delivery device to create steam and this energy is delivered into the prostate tissue through emitter holes in the delivery device needle to destroy the targeted obstructive prostate tissue that causes BPH.

During the treatment, saline is delivered through the device to enable visualisation and to keep the urethra cool and protect it from the thermal effects of the vapour during treatments.

What are the Benefits of the rezum Therapy System?

• Preservation of sexual function
• Significant improvement in BPH symptoms
• A rapid return to normal daily activities
• Fewer adverse events

The rezum therapy system offers an alternative to standard BPH management and has been supported by The National Institute of Clinical Excellence (NICE).
