In this study, the optical and thermal characteristics of the various commercially available devices for treating benign prostatic hyperplasia, using transurethrally delivered Nd:YAG laser light, were evaluated. To calculate the optimal parameters for each delivery system, the created tissue effect was dynamically modeled. Optically the devices were evaluated using by measuring the 3D irradiance distribution in a water environment. The thermal behavior of the devices was studied by a specially developed thermal imaging technique. The optical and thermal characteristics of the devices together with optical and thermal parameters of prostatic tissue were used as an input for a theoretical model to predict the extent of laser induced permanent damage and thus the effect of the device. Results show the influence of beam profile, spot size and secondary reflections of each laser prostatectomy device and modeling its therapeutic effect, will contribute to obtain an optimal dosimetry with best fitted parameters for each individual device.
