Objective
Rezum technology uses heat from radiofrequency-generated water vapour to ablate prostate tissue. We evaluate the introduction of this thermal therapy to an Irish teaching hospital for the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia.
Methods
A pilot study of men with moderate to severe lower urinary tract symptoms who underwent Rezum treatment to the prostate was performed. Perioperative efficacy was evaluated using international prostate symptom score (IPSS), quality of life score (IPSS-QOL), uroflowmetry and post-void residual (PVR) volumes. Costs were evaluated and compared against matched patients undergoing the standard of care, transurethral resection of the prostate (TURP).
Result
Ten patients with a mean age of 70 ± 9 years who met the inclusion criteria underwent Rezum treatment. Mean PSA was 4.73 ± 4 ng/mL and mean prostate volume 72 ± 30 cc. Rezum therapy significantly improved both IPSS by 74% from mean baseline score of 20.8 ± 4 to 5.3 ± 1.49 (p < 0.001) and IPSS-QOL score by 84% from mean baseline score of 4.4 ± 0.7 to 0.6 ± 0.7 (p < 0.001) at 3 months. Maximum flow rate increase by 44% from 9.26 ± 2.5 to 13.34 ± 2.3 mL/s (p < 0.001). When compared to ten matched patients undergoing TURP in the same period, there was a significant cost saving of €1986.52 per patient for Rezum, overall up-front cost saving of €22,819 with an additional 19 bed days and 5 theatre hours spared.
Conclusion
Rezum, a minimally invasive thermal therapy, provides significantly improved symptom relief and quality of life with a significant cost saving to the institution.
