Transrectal hyperthermia effectively improved benign prostatic hyperplasia symptoms. Over half of patients experienced sustained relief six months post-treatment, indicating a promising therapeutic option.

Area of Science:

Urology
Oncology
Medical Physics

Context:

Benign prostatic hyperplasia (BPH) affects a significant portion of aging men.
Current BPH treatments have limitations and side effects.
Minimally invasive therapies are sought for BPH management.

Purpose:

To evaluate the efficacy and safety of transrectal hyperthermia for benign prostatic hyperplasia.
To investigate the thermal distribution and cellular effects of microwave-induced hyperthermia in prostatic tissue.

Summary:

Thirty BPH patients received transrectal hyperthermia (43.0°C) twice weekly for ten sessions.
In vitro studies showed optimal heating at 1.5 cm from the microwave source.
Histopathology revealed hyperthermia initially affects interstitial tissues, then epithelial cells.

Significant improvements in subjective symptoms, residual urine volume, and urodynamics were observed.

53% of patients maintained improvements six months post-treatment.

Impact:

Transrectal hyperthermia demonstrates significant short- and medium-term efficacy for BPH symptom relief.
The findings support hyperthermia as a viable, less invasive treatment option for BPH.
Further research can optimize hyperthermia protocols for enhanced BPH patient outcomes.
