摘要： There is provided an indwelling ureteral (ureteric) stent comprised of a hollow flexible tube with an upper end section, a substantially straight middle section and a lower end section. The upper and lower sections are preferably coiled. The coiled upper section has a diameter between 1 and 2.5 cm which retains the upper section of the stent in the kidney, and has perforations in the surface to allow drainage of urine from the kidney into the tube. The lower coiled section of the stent is G-shaped. The tip of this lower section assumes the horizontal portion of the G shape and contains an integral valve. The integral valve maintains an open flow of urine from the kidney to the bladder, but prevents the reflux of urine into the kidney during bladder contraction. The stent further comprises a small cuff or series of studs behind said valve against which a stent pusher may rest.
