Ultrasound-guided transperineal laser ablation for percutaneous treatment of benign prostatic hyperplasia: a new minimally invasive interventional therapy.

Although there are different treatments for benign prostate hyperplasia, their efficacy and safety differ. We are currently exploring a new minimally invasive interventional therapy for benign prostatic hyperplasia (BPH).

To determine the feasibility, effectiveness, and safety of ultrasound-guided transperineal laser ablation (US-TPLA) for the treatment of BPH.

Twenty patients with BPH (mean age = 73.9 ± 9.2 years) who underwent US-TPLA from June 2018 to January 2020 with a subsequent six-month follow-up were retrospectively reviewed. After local anesthesia, a 21-G trocar was inserted into the prostate tissue under ultrasound monitoring, followed by 1064 nm diode laser irradiation. Changes in international prostate symptom score (IPSS), quality of life (QoL), maximum urinary flow rate (Qmax), postvoid residual (PVR), prostate volume, and complications were evaluated six months after surgery.

All patients underwent the operation successfully without serious complications. After six months, the average IPSS improved from 22.7 ± 5.3 to 9.1 ± 3.2 (P < 0.001), the QoL improved from 4.9 ± 1.7 to 2.3 ± 1.3 (P < 0.001), the Qmax improved from 8.5 ± 3.0 to 15.2 ± 4.8 mL/s (P < 0.001), the PVR increased from 78.7 ± 58.8 to 30.3 ± 34.2 (P < 0.05), and the mean prostate volume ranged from 70.8 ± 23.8 to 54.7 ± 20.9 mL (P < 0.05).

US-TPLA is safe and feasible for the treatment of BPH. An evaluation at the six-month follow-up is effective.
