摘要：A system and method for safely heating cancerous and pre-cancerous
conditions of the prostate, as well as benign and pre-benign lesions (any localized
珠海去香港pathological change in the prostate tissue) by irradiation of the prostate tissue with coherent phad array or non-coherent energy is introduced. Microwave energy and prostate compression provide preferential heating of high-water content prostate carcinoma and benign cells in the prostate compared to the surrounding lower-water content normal prostate tissues and tissue surrounding the prostate. To coherently focus the energy, such as microwave energy, in the prostate, the patient's prostate can be compresd via a urethral and rectal balloon and either a single electric-field probe, inrted in the central portion of the prostate, or two noninvasive electric-field nsors on the urethral and rectal walls, can be ud to measure a feedback signal to adjust the energy pha delivered to the applicators located in the urethra and in the rectum. The initial energy power delivered to the energy applicators is t to a desired value that is known to produce a desired increa in temperature in the prostate. Temperature feedback nsors are ud to measure urethral and rectal wall temperatures during treatment to adjust the energy power delivered to the applicators to avoid o
verheating the urethral and rectal walls. The energy delivered to the applicators is monitored in real time during treatment, and the treatment is completed when a desired total energy do has been administered. The system according to the invention can heat and destroy the prostate carcinoma and benign cells sufficiently in order to prevent prostate cancer and benign prostatic hyperplasia. The treatment is administered as a preventative for cancer and BPH, when a patient's PSA level is less than 4 and for BPH, when a patient's AUA Symptom Index scores less than 13.
