Summary
Cooled transurethral microwave thermotherapy is effective for benign prostatic hyperplasia regardless of prostate size. This treatment offers similar outcomes for men with small or large prostates, addressing prior misconceptions.
Area of Science:
- Urology
- Medical Technology
Background:
- Transurethral microwave thermotherapy (TUMT) is an established treatment for lower urinary tract symptoms due to benign prostatic hyperplasia.
- Concerns exist regarding the efficacy of cooled TUMT for smaller prostates.
Purpose of the Study:
- To evaluate if baseline prostate size influences patient response to cooled transurethral microwave thermotherapy.
- To determine the long-term effectiveness of cooled TUMT across different prostate sizes.
Main Methods:
- A meta-analysis of 713 patients from six studies using Urologix cooled TUMT devices.
- Analysis of American Urological Association Symptom Index, peak flow rate, quality-of-life, and symptom problem index over 60 months.
- Statistical analysis using general linear models and repeated measures.
Main Results:
- No significant effect of baseline prostate size on treatment outcomes was observed for over five years.
- Patient-reported pain (Visual Analog Scale) during treatment was not influenced by prostate size.
Conclusions:
- Cooled transurethral microwave thermotherapy demonstrates comparable efficacy in patients with small and large prostates.
- This treatment modality should be considered for benign prostatic hyperplasia in men with prostates of all sizes.
