Evaluating a new treatment for urinary symptoms caused by prostate enlargement

Evaluation of the Functional Outcomes After Bilateral, 3D Ultrasound-guided Focal Thermal Ablation of the Prostate Transition Zone, in Patients with Benign Prostatic Hyperplasia-related Obstruction

PHASE2 · Assistance Publique - Hôpitaux de Paris · NCT06212453

This study is testing a new microwave treatment for men with urinary problems caused by an enlarged prostate to see if it works better and is safer than traditional surgery.

What this trial studies

This study aims to assess the effectiveness of transperineal focal microwave ablation (TMA) for treating lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). It is a prospective pilot study conducted at a single institution, focusing on a minimally invasive approach that utilizes 3D ultrasound guidance for precision. The study compares this new method to traditional surgical interventions, which often come with significant complications. By using microwave thermal ablation, the researchers hope to provide a safer and more effective treatment option for patients suffering from BPH-related obstruction.

Who should consider this trial

Good fit: Ideal candidates are men over 40 with moderate to severe BPH symptoms and specific prostate volume criteria.

Not a fit: Patients with a history of prostate cancer or those who have undergone previous prostate surgeries may not benefit from this treatment.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce complications and improve quality of life for patients with BPH.

How similar studies have performed: While similar minimally invasive techniques have shown promise, this specific approach using TMA is relatively novel and has not been extensively tested.
