Prostatic microwave therapy: A pilot study for technology assessment

Objective. The Genemed Genetherm S 150 is an easy to use and comparatively inexpensive device for administering prostatic microwave therapy. This study was aimed at testing the efficacy and safety of this machine in a pilot study. Methods. Sixteen patients with benign prostatic hypertrophy participated in the study, but only fourteen were evaluable. All received one hour of microwave therapy where the mean temperature was 45.7±0.2 °C. Symptom scores (International Prostate Symptom Score and Quality of Life Assessment), peak flow rates and post void residuals were used to evaluate participants prior to and three months following their treatment. Results. The results of this study show a statistically significant improvement in mean symptom scores. There was no significant change in mean peak flow rates while a statistically significant increase in mean post void residual occurred. Individually, however, only one patient experienced an improvement in all of the above parameters. There were no undesirable side effects during or after treatment. Conclusions. We conclude that the results of this pilot study do not warrant further study of this device, despite its practicality and safety.
