A ureteral stent (50; 150; 250; 350; 450; 550; 650; 750; 850) for placement in a bladder , a kidney and a ureteral passageway connecting the bladder and kidney, the ureteral stent including: a bladder portion (52; 152; 252; 352; 452; 652; 752; 852) configured to be positioned in the bladder, the bladder portion being resilient and biased in an unrestrained position to prevent the bladder portion from migrating into the ureteral passageway (16;18) when positioned in the bladder, the bladder portion including at least one opening (60; 160) in a wall thereof; a kidney portion (54; 154; 254, 354; 454; 654; 754; 854) configured to be positioned in the kidney and the ureteral passageway, the kidney portion having a ureter portion (78; 278; 378; 478) configured to be positioned in the kidney and the ureteral passageway to place the ureteral passageway in an open state and a resilient fixing portion (76; 176; 276; 376) biased in an unrestrained position to secure the resilient fixing portion in the kidney when positioned in the kidney, the kidney portion including at least one opening in a wall thereof at least one tether (56; 156; 256; 356; 556; 656) coupled to the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state; wherein the at least one opening (60; 80) in the bladder and kidney portions provides a passage between an outside of the bladder and kidney portions and an inside of the bladder and kidney portions for receiving the tether, wherein the tether extends from the inside of the bladder and kidney portions to the outside of the bladder and kidney portions, wherein the tether has a first end and a second end coupled together outside the bladder and kidney portions forming a coupled tether portion, characterized in that a sleeve coupled to the wall of the bladder portion adjacent the opening in the wall, wherein the sleeve covers the coupled tether portion. a bladder portion (52; 152; 252; 352; 452; 652; 752; 852) configured to be positioned in the bladder, the bladder portion being resilient and biased in an unrestrained position to prevent the bladder portion from migrating into the ureteral passageway (16;18) when positioned in the bladder, the bladder portion including at least one opening (60; 160) in a wall thereof; a kidney portion (54; 154; 254, 354; 454; 654; 754; 854) configured to be positioned in the kidney and the ureteral passageway, the kidney portion having a ureter portion (78; 278; 378; 478) configured to be positioned in the kidney and the ureteral passageway to place the ureteral passageway in an open state and a resilient fixing portion (76; 176; 276; 376) biased in an unrestrained position to secure the resilient fixing portion in the kidney when positioned in the kidney, the kidney portion including at least one opening in a wall thereof at least one tether (56; 156; 256; 356; 556; 656) coupled to the bladder portion and the ureter portion to allow the bladder portion to float in the bladder and to allow a ureter orifice connecting the ureteral passageway to the bladder to move between a compressed state and an uncompressed state; wherein the at least one opening (60; 80) in the bladder and kidney portions provides a passage between an outside of the bladder and kidney portions and an inside of the bladder and kidney portions for receiving the tether, wherein the tether extends from the inside of the bladder and kidney portions to the outside of the bladder and kidney portions, wherein the tether has a first end and a second end coupled together outside the bladder and kidney portions forming a coupled tether portion, characterized in that a sleeve coupled to the wall of the bladder portion adjacent the opening in the wall, wherein the sleeve covers the coupled tether portion. <EOS>
