To evaluate the feasibility, safety, and efficacy of ultrasound-guided transperineal laser ablation (TPLA) as a new minimally invasive surgical therapy (MIST) for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH).
Under local anesthesia and conscious sedation up to two laser fibers for each prostatic lobe were inserted under US-guidance by a percutaneous approach. TPLA was performed using a continuous wave diode laser (SoracteLite-EchoLaserX4) able to generate a light-induced thermal heating and subsequent coagulative necrosis of the prostatic tissue. Patients were evaluated at 3, 6, and 12 months after TPLA.
Twenty-two consecutive patients were prospectively enrolled (median age 61.9 years). All procedures were well tolerated and no procedural complications were recorded. Median catheterization time was 7 days, while the median hospitalization time was 1 day. Three out of twenty-two patients (13.6%) experienced acute urinary retention and two (9.1%) of them urinary tract infection requiring major antibiotic treatment. At 3, 6, and 12 months, median prostate volume significantly decreased by a - 21.3%, - 29%, and - 41%, respectively. At the same time point, median IPSS was 8 (- 63.6%), 5 (- 74%), and 6 (- 75%), while median QoL score was 1 in all the scheduled timepoints of follow-up. The median postoperative Qmax at 3, 6, and 12 months improved by + 57.8%, + 98%, and + 115.8%, respectively. Ejaculatory function was preserved in 21 out of 22 patients (95.5%).
TPLA of the prostate appears to be a promising MIST for BPH. Long-term results and comparative studies against standard treatments are warranted before implementations of this technique in the urologist's armamentarium.
