1. A ureteral stent comprising:
an elongated flexible tubular member having a lumen extending along a length thereof, the tubular member defining a bladder retention member at a first end thereof and a renal retention member at a second end thereof and an intermediate portion therebetween;
wherein the bladder retention member comprises:
multiple turns within a plane in which the intermediate portion lies; and
a plurality of portions configured, shaped, and structured to facilitate segmenting of the bladder retention member in vivo; and
wherein:
the bladder retention member includes radiopaque markings which are identifiable in vivo and positioned to identify the plurality of portions of the bladder retention member in vivo; and
each of the plurality of portions of the bladder retention member is positioned at a respective one of the radiopaque markings along the bladder retention member which is identifiable in vivo, the bladder retention member portions and radiopaque markings together structured and configured and positioned to facilitate incremental segmenting of the bladder retention member in vivo to adjust a length of the bladder retention member in vivo in segments corresponding to the incremental portions identified by the radiopaque markings.
