FACILITATING DRAINAGE

摘要

A prostatic stent (3) comprises a body member (5) and a retaining member. The body member (5) includes a distal terminating end (4), a proximal end portion (7), and a lumen extending within the body member to allow fluid drainage through the body member. The body member (5) is sized for placement substantially within the prostatic section of the urethra, with the distal terminating end (4) located proximal of an external sphincter to allow normal operation of the external sphincter. The retaining member (8) extends from the proximal end portion (7) of the body member (5). The retaining member (8) is collapsible into a first state to allow passage of the prostatic stent (3) into the urethra, and the retaining member (8) is expandable into a second state when located in a bladder to hold the body member (5) in place substantially within the prostatic section of the urethra.
