Neurons are energy-demanding *** in energy metabolism can quickly interrupt neuronal function,leading to cell death and *** instance,ischemia rapidly depletes adenosine triphosphate(ATp)thereby disrupting energy-dependent cellular processes crucial for homeostasis,and axon degeneration is preceded by a collapse of axonal ATp levels.

Objective: To evaluate transperineal laser ablation (TpLA) with Echolaser® (Echolaser® TpLA, Elesta S.p.A., Calenzano, Italy) as a treatment for benign prostatic hyperplasia (BpH) and prostate cancer (pCa) using the Delphi consensus ***: Italian and international experts on BpH and pCa participated in a collaborative consensus project. During two rounds, they expressed their opinions on Echolaser® TpLA for the treatment of BpH and pCa answering online questionnaires on indications, methodology, and potential complications of this technology. Level of agreement or disagreement to reach consensus was set at 75%. If the consensus was not achieved, questions were modified after each round. A final round was performed during an online meeting, in which results were discussed and ***: Thirty-two out of forty invited experts participated and consensus was reached on all topics. Agreement was achieved on recommending Echolaser® TpLA as a treatment of BpH in patients with ample range of prostate volume, from mL (80%) to >80 mL (80%), comorbidities (100%), antiplatelet or anticoagulant treatment (96%), indwelling catheter (77%), and strong will of preserving ejaculatory function (100%). majority of respondents agreed that Echolaser® TpLA is a potential option for the treatment of localized pCa (78%) and recommended it for low-risk pCa (90%). During the final round, experts concluded that it can be used for intermediate-risk pCa and it should be proposed as an effective alternative to radical prostatectomy for patients with strong will of avoiding urinary incontinence and sexual dysfunction. Almost all participants agreed that the transperineal approach of this organ-sparing technique is safer than transrectal and transurethral approaches typical of other techniques (97% of agreement among experts). pre-procedural assessment, technical aspects, post-procedural catheterization, pharmacological therapy, and expected outcomes were discussed, leading t
