In the method of treating internal body tissue, the steps that include providing an endoscope having a viewing channel, with an elongated optical stem, associated with the channel, and defining a longitudinal axis; providing a longitudinally elongated sheath received on a stem and supported for controlled rotation about an axis and into selected angular position relative to a support, to gain access to the selected urethral tissue zone to be treated; providing means to be rotated with the sheath to be targeted toward and to eject flowable treatment material onto or into tissue at a zone; and rotating the sheath and ejecting treatment material at a selected zone.
