Experimental setups for laser treatment of urethra with balloon-assisted diffusing applicator (BDA): (A) geometry of urethra and BDA for numerical simulations (U = urethra; left image = isotropic view; top right image = longitudinal view; bottom right image = cross-sectional view). Note that the BDA is placed inside the urethral tissue (i.e., diameter = 7 mm; length = 35 mm). (B) Evaluation of temperature in ex vivo porcine urethral tissue with infrared (IR) camera and fiber bragg grating (FBG) sensor. (C) In vivo porcine urethral tissue test with 980 nm laser (B = bladder; IUS = internal urinary sphincter; AL = active length; left image = porcine animal model; top right images = photographs; bottom right images = illustration of urethra during laser irradiation).
