Patients with benign prostate enlargement can now access a therapy called prostate artery embolisation through The London Clinic.
More than a third of men over 50 have an enlarged prostate, making it difficult to pass urine.
The non-surgical procedure, which is carried out under local anaesthetic as a day case, provides relief for lower urinary tract symptoms caused by the condition.
The charitable hospital says it is one of the first private hospitals in the UK to make the treatment available as a routine procedure, joining Spire Healthcare and HCA Healthcare UK.
Separately, the NHS recently received approval from the National Institute for Health and Care Excellence to treat enlarged prostate patients with a new steam treatment, saying evidence shows the procedure is as effective as surgery.
