Transient simulation of laser ablation based on Monte Carlo light transport with dynamic optical properties model

open access: yesScientific Reports, 2023
Laser ablation is a minimally invasive therapeutic technique to denature tumors through coagulation and/or vaporization. Computational simulations of laser ablation can evaluate treatment outcomes quantitatively and provide numerical indices to determine

Risk Factors for Transurethral Coagulation for Hemostasis During Holmium Laser Enucleation of the Prostate [PDF]

open access: yesInternational Neurourology Journal, 2022
Purpose We aimed to identify risk factors for transurethral coagulation (TUC) using bipolar electrocautery for hemostasis during holmium laser enucleation of the prostate (HoLEP) surgery for benign prostatic hyperplasia (BPH).
