Abstract
A ureteral stent is configured for improved patient comfort and aftercare. The stent can have one or more of the following features: a distal portion with a somewhat flattened, non-circular cross-section that provides reduced irritation and elimination of urine reflux; a proximal portion with a helical coil shape that allows self-anchoring of the stent below the kidney; and a portion along the body of the stent having a coil shape that allows self-adjustment of the stent with ureteral movement.
