Transperineal Interstitial Laser Ablation

This procedure is based on the principle of percutaneous tissue ablation. Depending on the prostate volume and shape, up to four applicators (21-gauge Chiba needle) are required and the procedure is guided by an ultrasound.

Transperineal interstitial laser ablation (TPLA) is performed under IV sedation combined with local perineal anesthesia and transrectal prostatic block.[23]

Mauri et al..[24] reported a retrospective multicenter study of 160 patients with a follow-up of at least 6 months and of 83 patients with a follow-up of at least 12 months. Mean hospital stay was 1.8 ± 0.4 days, and mean catheterization time was 12.6 days.

At 12 months, IPSS improved from 22.5 ± 4.5 to 7.0 ± 2.9 (P < 0.001), Qmax from 8.6 ± 5.2 to15.0 ± 4.0 ml/s (P < 0.001). Complications were mostly low grade.

The authors reported 2/160 (1.2%) patients with lost of ejaculatory function (ejaculatory function was not evaluated with a specific questionnaire).
