摘要:
A ureteral stent comprising a short renal coil made of a pliable material and a wick portion made of a material having a hydrophilicity or hydrophobicity different from that of the renal coil and extending from a ureteropelvic junction to a bladder so as to assist in the transfer of urine out of a kidney and into the bladder and to improve patient comfort. Due to increased hydrophilicity or hydrophobicity, wick may be significantly smaller in diameter than renal coil, resulting in less reflux of urine into the kidney and further decreasing patient discomfort. The stent may further comprise one or more couplers between the renal coil and wick portion, and the wick portion may comprise a sheath surrounding an elastic core to prevent kinking and enhance the ability of the wick portion to move with the patient. A method of ureteral stent placement is also disclosed.
