The role of an advanced thermotherapy device in prostatic voiding dysfunction

Area of Science:

• Urology
• Medical Devices
• Therapeutics

Background:

• Benign prostatic hyperplasia (BPH) is a common condition causing lower urinary tract symptoms.
• Transurethral thermotherapy (TUMT) is a treatment option for symptomatic BPH.
• Evaluating TUMT efficacy with advanced urodynamic analysis offers deeper insights.

Purpose of the Study:

• To assess the effectiveness of an advanced TUMT device (T3, Urologix).
• To integrate urodynamic analysis into the standard BPH evaluation protocol post-TUMT.
• To determine if urodynamics can predict treatment outcomes.

Main Methods:

• Fifty men with symptomatic BPH underwent standard assessments (AUA score, uroflowmetry, ultrasonography) and advanced urodynamic analysis.
• TUMT was administered using a focused microwave energy system.
• Evaluations were performed pre-treatment and at multiple follow-up points up to 12 months.

Main Results:

• Significant improvements observed at 3 months post-TUMT, including a 63% decrease in AUA score and a 64% increase in peak flow rate, sustained at 1 year.
• Advanced urodynamics revealed reduced obstruction severity in 52% and improved detrusor contractility in 86% of patients.
• Patients with marginal obstruction showed significantly better outcomes than those with unequivocal obstruction.

Conclusions:

• Advanced urodynamic analysis is valuable for predicting TUMT outcomes in BPH patients.
• Thermotherapy yields superior results in patients with marginal prostatic bladder outflow obstruction.
• TUMT offers a viable treatment option for symptomatic BPH, with predictable outcomes based on obstruction severity.
