The 30-minute transurethral microwave thermotherapy (TUMT) offers superior results with improved patient comfort and reduced catheterization needs. This modified TUMT technique achieves higher intraprostatic temperatures, leading to better outcomes.

Area of Science:

  • Urology
  • Minimally Invasive Therapies

Background:

  • Transurethral microwave thermotherapy (TUMT) presents variability in protocols and outcomes, causing clinical confusion.
  • Previous TUMT protocols often involved longer treatment times and higher patient discomfort.

Purpose of the Study:

  • To evaluate the efficacy and patient experience of a novel 30-minute transurethral microwave thermotherapy (TUMT) protocol.
  • To compare the outcomes of the 30-minute TUMT with previous treatment protocols.

Main Methods:

  • A modified 30-minute TUMT protocol was implemented in 16 patients.
  • This protocol featured an initial power of 80 W and urethral cooling at 48°F (8°C).
  • Intraprostatic temperatures, patient discomfort, analgesic requirements, and post-treatment outcomes were assessed.

Main Results:

  • Significant improvements in patient comfort, with reduced analgesic needs (11 mL remifentanil) and low pain scores (0-2).
  • All patients in urinary retention were catheter-free within one week; only one patient required post-treatment catheterization.
  • Improved urinary flow rates, reduced postvoid residuals, and prostatic cavity formation in nearly all patients observed via ultrasound at 3 months.

Conclusions:

  • The 30-minute TUMT protocol demonstrates superior clinical outcomes compared to previous methods.
  • This modified approach offers enhanced patient comfort, minimal discomfort, and reduced need for catheterization.
  • Higher intraprostatic temperatures achieved with this technique contribute to effective treatment and prostatic cavity formation.
