Summary
High-power transurethral microwave thermotherapy significantly improves benign prostatic hyperplasia symptoms and urinary flow. However, this advanced treatment is linked to higher short-term side effects compared to low-power options.
Area of Science:
- Urology
- Medical Devices
- Therapeutic Technology
Background:
- Benign prostatic hyperplasia (BPH) is a common condition affecting aging men.
- Transurethral microwave thermotherapy (TUMT) offers a minimally invasive treatment option for BPH.
- Continuous research aims to optimize TUMT efficacy and patient outcomes.
Purpose of the Study:
- To evaluate the effectiveness of high-power TUMT using the Prostcare device for BPH.
- To identify key factors influencing treatment outcomes in TUMT for BPH.
Main Methods:
- Utilized high-power TUMT with the Prostcare device since April 1992.
- Focused on apparatus development, accessories, and treatment performance optimization.
- Assessed outcomes through symptom scores, quality-of-life, maximal flow rate, residual/voided volumes, and pressure-flow studies.
Main Results:
- High-power TUMT demonstrated significant improvements in BPH symptoms, quality of life, and urinary flow parameters after 6 months.
- Pressure-flow data indicated a significant reduction in minimal urethral opening pressure.
- Higher treatment power correlated with increased short-term morbidity compared to low-power TUMT.
Conclusions:
- High-power TUMT is an effective treatment for BPH, yielding significant functional improvements.
- Treatment outcomes are influenced by power, temperature, technique, heat distribution, and localization.
- Balancing efficacy with short-term morbidity is crucial in optimizing high-power TUMT protocols.
