The aim of this study, with Dr Fredrik Stenmark as lead author, was to evaluate the short- and long-term retreatment risk in men with a large prostates and benign prostate obstruction (BPO) or chronic urinary retention, all primarily treated with CoreTherm.

570 men with prostate volumes ≥ 80 ml treated with CoreTherm 1999–2015 were included in the study and have been followed until December 2019. Only 12% needed further surgical treatment during the follow-up period which averaged 11 years but up to 20 years. The long-term re-treatment rate in the study was 23% where the majority of these could be retreated with CoreTherm or TURP and for only 3% open surgery was necessary to resort to.

The authors conclude that CoreTherm is a suitable outpatient treatment option in patients with profoundly enlarged prostates, regardless of age, prostate size, and reason for treatment.

CEO Johan Wennerholm comments: "It is both important and gratifying that the academy continues to study our method. For men with very large prostate glands (larger than 80 ml), open surgical procedures are often offered as the size of the gland makes them unsuitable for a TUR-P. This means that the operations are performed under general anesthesia, with sometimes a high risk of bleeding and other complications, in addition to a in many cases time-consuming and expensive operation. We now have scientific evidence that CoreTherm is a safe and highly effective treatment option, both in the short and long term, for this patient group."
