What is claimed is: 
     
         1 . A stent for treating a urologic disorder, comprising:
 a stent body having a deployed configuration with an outer surface portion having a plurality of projecting elements directed outward from the outer surface portion such that the plurality of projecting elements are configured to engage tissue in a wall of a lumen in a patient's urinary tract, wherein the stent body has a central passageway extending therethrough; and   wherein the stent body is transformable to an inverted configuration in which the outer surface portion is configured to invert within an end of the stent causing movement of the projecting elements within the central passageway of the stent body which disengages the projecting elements from the tissue for withdrawal of the stent body from the lumen.
