Abstract
The present invention provides a method for diagnosing or treating prostatic tissue in a human or animal patient which comprises sensitizing the prostatic tissue with an effective amount of a photosensitive composition which accumulates in the prostatic tissue and exposing the sensitized tissue to a source of light energy for a predetermined time and intensity sufficient to cause cellular and/or tissue function of the sensitized prostatic tissue to diminish or cease.
Claims12
A method for treating the symptoms associated with benign prostatic hyperplasia (BPH) or prostatitis of noncancerous prostatic tissue in a human or animal patient comprising:
- (a) sensitizing noncancerous prostatic tissue with an effective amount of a therapeutic photosensitive composition with accumulates in the tissue and thereafter (b) exposing the sensitized prostatic tissue to a source of light energy for a predetermined period of time and at a predetermined wavelength, whereby the photosensitive composition in the light-exposed prostatic tissue absorbs the light or undergoes a photochemical reaction.
