[Single transurethral microwave therapy of benign prostatic hyperplasia]

Area of Science:

• Urology
• Minimally Invasive Therapies
• Medical Devices

Context:

• Benign prostatic hyperplasia (BPH) is a common condition causing lower urinary tract symptoms.
• Traditional treatments include surgery and medication, which can have side effects.
• Transurethral microwave thermotherapy (TUMT) offers a less invasive alternative.

Purpose:

• To evaluate the efficacy and safety of transurethral microwave thermotherapy (TUMT) for treating benign prostatic hyperplasia (BPH).
• To assess changes in symptom scores, urinary flow rate, and residual urine volume post-TUMT.

Summary:

• TUMT utilizes microwaves to heat periurethral prostatic tissue, causing irreversible cell damage while protecting the urethra through cooling.
• Patients undergoing TUMT experienced significant improvements in Madsen symptom scores and reduced residual urine.
• Urinary flow rates showed a modest increase, and prostate volume reduction was minimal.

Impact:

• TUMT provides a safe and effective outpatient treatment option for symptomatic BPH.
• The procedure demonstrates significant symptom relief and improved urinary function in eligible patients.
• Further research may explore optimizing TUMT parameters for enhanced prostate volume reduction.
