Transperineal laser ablation for percutaneous treatment of benign prostatic hyperplasia: a feasibility study. Results at 6 and 12 months from a retrospective multi-centric study.

To investigate the effectiveness and safety of SoracteLite™-transperineal percutaneous laser ablation (TPLA) in the treatment of patients with symptomatic benign prostatic hyperplasia (BPH) at 6 and 12 months follow-up.

Patients with urinary symptoms secondary to BPH underwent TPLA under local anesthesia in four centers. Under US guidance, up to four 21G applicators were inserted in the prostatic tissue. Each treatment was performed with diode laser operating at 1064 nm changing the illumination time according to prostate size. The primary end-points of this study were change in IPSS, PVR, Qmax, QoL, and prostatic volume at 6 an 12 months from SoracteLiteTM TPLA treatment. Secondary end-point was the assessment of complications.

Analysis was performed on data 160 patients (mean age 69.8 ± 9.6 years) with at least 6 months follow and of 83 patients (mean age 67.9 ± 8.7 years) with at least 12 months follow-up. At 6 months, IPSS improved from 22.5 ± 5.1 to 7.7 ± 3.3 (P < 0.001), PVR from 89.5 ± 84.6 to 27.2 ± 44.5 ml (P < 0.001), Qmax from 8.0 ± 3.8 to 14.3 ± 3.9 ml/s (P < 0.001), QoL from 4.5 ± 1.1 to 1.8 ± 1.0 (P < 0.001), volume from 75.0 ± 32.4 to 60.3 ± 24.5 ml (P < 0.001). At 12 months, IPSS improved from 22.5 ± 4.5 to 7.0 ± 2.9 (P < 0.001), PVR from 71.7 ± 93.9 to 17.8 ± 51.0 ml (P < 0.001), Qmax from 8.6 ± 5.2 to 15.0 ± 4.0 ml/s (P < 0.001), QoL from 4.2 ± 0.6 to 1.6 ± 0.9 (P < 0.001), volume from 87.9 ± 31.6 to 58.8 ± 22.9 ml (P < 0.001). 7/160 (4.3%) grade I and 1/160 (0.6%) grade III complication occurred.

SoracteLite™ TPLA allows significant improvement of IPSS, Qol, Qmax, PVR, and reduction of prostatic volume at 6 and 12 months.
