A stent useful for treatment of prostatic urethral hypertrophy having a cylindrical conduit with a conical flange on one end and an annular flange on the other. The stent is constructed of a medical grade elastomer whereby it may be compressed for implantation and can thereafter be left in place for extended periods of time without adverse reactions by the patient. The stent is placed with a constructed endoscope with a novel everted, tubular retaining member to hold the stent in place during the implantation procedure.
