BACKGROUND/OBJECTIVES: Laser ablation is a promising technique for tissue-debulking in patients with symptomatic benign prostatic hyperplasia (BPH). This study evaluated the effects of focused laser ablation of the prostate (FLA) on urinary symptoms for patients with BPH. METHODS: Since 2018, 62 patients had bilateral prostate FLA for prostate cancer and/or symptomatic BPH, defined as an international prostate symptom score (IPSS) ≥11, and have 6-month follow-up data. Urinary and sexual health were scored with standardized surveys while imaging defined prostate anatomy. FLA was performed as an outpatient procedure with either transrectal MRI-guided ( RESULTS: All patients had technically successful FLA and 6-month clinical and imaging follow-up. At 6-month follow-up, mean IPSS was reduced by 43% relative to baseline (10.4 vs. 18.4), mean prostate volume was reduced by 30% (42.2 vs. 60.5 mL), and mean PSA was reduced by 58% (4.3 vs. 10.2 ng/mL). All of these changes were statistically significant ( CONCLUSIONS: FLA is a safe and effective tissue-debulking technique for patients with symptomatic BPH. This outpatient procedure requires minimal procedure time and can be performed without the need for operating rooms or cystoscopy. Our results are consistent with those of previous studies indicating that FLA preserves sexual function.
