Transurethral thermotherapy using the Prostatron device

Area of Science:

• Urology
• Minimally Invasive Surgery
• Medical Devices

Background:

• Benign prostatic hyperplasia (BPH) is a common condition causing lower urinary tract symptoms.
• Transurethral microwave thermotherapy (TUMT) is a minimally invasive treatment option for BPH.
• TUMT utilizes microwave energy to heat and ablate prostatic tissue.

Purpose of the Study:

• To review available data on low- and high-energy TUMT for BPH treatment.
• To provide a perspective on patient selection and future developments in TUMT.
• To compare the efficacy of different TUMT energy modalities.

Main Methods:

• Systematic review of clinical studies evaluating low- and high-energy TUMT.
• Analysis of patient parameters and treatment outcomes.
• Comparison of efficacy based on prostate size and obstruction severity.

Main Results:

• Both low- and high-energy TUMT software modalities have demonstrated clinical effectiveness.
• Low-energy TUMT is suitable for smaller prostates with lower-grade obstruction and mild symptoms.
• High-energy TUMT is effective for deobstruction in larger prostates with moderate to severe obstruction.

Conclusions:

• Patient selection is crucial for optimizing TUMT outcomes.
• Baseline parameters can predict response to high-energy TUMT, but total energy delivered is key.
• Future research should focus on quantifying prostate vascularization and histology, and on reducing treatment time and morbidity.
