Leading urologist, Mr Andrew Ballaro, talks to us about an exciting new treatment for benign prostate enlargement, a condition that affects many men in their older age. Rezūm presents a minimally-invasive approach that has shown to produce good results, without the risk of invasive surgery or the complications associated with it.

How would I recognise the symptoms of BPH?

The prostate gland is an organ, normally the size of a walnut, which encircles the urethra (the tube that drains the urine from the bladder to the penis). Benign prostatic hyperplasia (BPH) is the medical term for an enlarged prostate and is characterised by lower urinary tract symptoms (LUTS) caused by the enlarged prostate blocking the flow of urine from the bladder.

LUTS include:

  • Urinary frequency (i.e. passing urine more often than normal)
  • Urinary hesitancy (i.e. finding it difficult to start passing urine or finding there is a longer than normal wait for the stream of urine to begin)
  • Poor urinary flow and dribbling at the end of the stream, or a stop-start stream
  • Getting up at night to pass urine
  • Feeling an urgent need to pass urine that is difficult to defer

Tell us about the new Rezūm treatment for benign prostate hyperplasia

Rezūm is a new minimally-invasive treatment recently approved for the treatment of BPH. It involves a short general anaesthetic and can also be performed under local anaesthetic, during which steam is injected into the obstructing prostate from inside the urethra. The steam causes shrinkage of the prostate and this significantly reduces the obstruction and improves urinary symptoms.

What are the advantages of Rezūm over other treatments (UroLift or TURP)?

The major advantage of Rezūm over conventional techniques, such as TURP and HoLEP, is that it does not involve surgical removal of large amounts of prostate tissue. This can be associated with heavy blood loss and complications, and also routinely causes loss of ejaculation (dry orgasm and infertility). The procedure is also much shorter than TURP or HoLEP and is usually a performed as a day-case. The results appear to be better than UroLift, another minimally-invasive operation for BPH, and, unlike UroLift, it does not involve implanting a plastic foreign-body into the prostate; the long term outcome of which is not yet known.

How well does Rezūm preserve sexual and urinary function?

Rezūm treatment significantly improves urinary symptoms resulting in, on average, a fifteen point improvement in symptoms scores. It preserves sexual function with only 4% of patients reporting an adverse effect on ejaculation.

How much does the Rezūm treatment cost?

Rezūm is approved by insurance companies and is at a competitive price to alternative procedures.


If you are male and experiencing urinary symptoms, as described above, make an appointment with an expert to investigate and treat these symptoms.

He has specialist surgical expertise in the management of kidney stone disease and benign prostate enlargement (BPE), and consistently publishes UK leading surgical outcomes for complex stone operations. He offers a choice of surgical procedures for benign prostatic enlargement tailored to the patient’s requirements including Holmium Laser prostatectomy (HOLEP) and is highly experienced in dealing with very large prostates and urinary retention, with every patient in a large series going home the day after surgery without a catheter.

Mr Ballaro takes satisfaction in providing second opinions, and is supported by a warm, skilled and responsive managerial team. Together they aim to provide the best possible outcome for each and every patient. Mr Ballaro's extensive training began after graduating from The Royal Free Hospital Medical School in London, and undertaking his surgical training at Oxford. He was awarded a fellowship from the Royal College of Surgeons of London and went on to complete higher urological training on the North London Training Scheme. This was followed by advanced training in complex stone surgery from national and international experts in his field.

Alongside his dedication to education, he is currently teaching trainees at the London Deanery, catering to various levels of expertise. Additionally, he has been honoured with a Hunterian Professorship from the Royal College of Surgeons of England, showcasing his commitment to scholarly pursuits. Holding a master’s degree in urology and an MD in clinical sciences from the Institute of Urology, Mr. Ballaro has extensively published research on bladder physiology and minimally invasive urological surgery. He is the co-author of the latest edition of the popular medical student textbook 'Lecture Notes in Urology'.
