Transurethral microwave thermotherapy (TUMT) is a safe and effective outpatient treatment for benign prostatic hyperplasia. Both low and high energy versions offer symptom relief, with high energy showing greater flow rate improvement but increased morbidity.

Area of Science:

  • Urology
  • Minimally Invasive Therapies

Background:

  • Benign prostatic hyperplasia (BPH) is a common condition affecting aging men.
  • Transurethral microwave thermotherapy (TUMT) is a minimally invasive treatment option for BPH.

Purpose of the Study:

  • To provide an overview of the current status of transurethral microwave thermotherapy (TUMT) in its low-energy (LE) and high-energy (HE) versions.
  • To evaluate the efficacy and safety of both LE-TUMT and HE-TUMT for BPH treatment.

Main Methods:

  • Review of existing studies on LE-TUMT and HE-TUMT.
  • Comparison of TUMT outcomes with sham procedures and transurethral resection of the prostate (TURP).

Main Results:

  • LE-TUMT demonstrates significant symptom improvement (75% of patients) and flow rate increase (35-40%).

  • HE-TUMT shows similar symptomatic improvement, with a greater flow rate increase (approx. 65%), but higher rates of retrograde ejaculation and retention.
  • Long-term studies indicate durability up to 5 years, with a small percentage of patients requiring subsequent TURP.

    • Conclusions:

    • TUMT is a safe, efficacious, and minimally invasive outpatient procedure for BPH symptom relief.
    • The availability of both LE and HE versions allows for patient selection based on obstruction severity.
    • TUMT offers a valuable treatment alternative for benign prostatic hyperplasia.
