At the distal portion, a retention end-piece is positioned for retaining the distal portion of the stent in the renal pelvis. The end-effector and the retention end-piece of the stent maintain the elongated body portion in situ. The end-effector may also include an inflatable balloon and may contain pharmaceutical or biologic agents for controlled release into the bladder.
