Abstract

Se describen un aparato y un procedimiento para el tratamiento de enfermedades de la prostata, que incluyen la BPH y el cáncer de prostata, utilizando energía concentrada de ultrasonidos aplicada transuretralmente para producir efectos hipertérmicos y termoterapéuticos en el tejido enfermo; una primera forma de realizacion preferida del aparato se basa en el control visual, y una segunda forma de realizacion preferida del aparato incorpora un transductor ultrasonico integrado de terapia y de formacion de imagen; el aparato y el procedimiento presentan la colocacion proxima del transductor de ultrasonido al tejido enfermo a tratar, dando como resultado una atenuacion menor del haz y la deposicion de una fraccion mayor del total de la energía de ultrasonidos emitida en la porcion seleccionada del tejido enfermo; la energía de ultrasonidos pasa de forma no traumática a través de la pared uretral y de otro tejido no enfocado; en el punto focal de la energía de ultrasonidos, se produce un calentamiento considerable del tejido enfermo para producir efectos hipertérmicos en el mismo, e incluso se alcanzan temperaturas termoterapéuticas más altas para producir la necrosis coagulativa del tejido enfermo.
