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, such as clamps, couplers, sutures, adhesives or receiving ends of the renal coil, and the wick portion may further comprise a sheath surrounding an elastic core to prevent kinking and enhance the ability of the wick portion to move with the patient. A novel method of ureteral stent placement is also disclosed.

The invention discloses a ureteral stent, which comprises a tubular body made of medical-grade polymer materials, wherein the ends of the tubular body are inwardly bent in opposite directions to a pigtail shape, and a larger groove (1) and a smaller groove (2) are symmetrically arranged at side walls of the tubular body with H-shaped cross sections. The diameter of the tubular body is 1.4-3.2 and the length thereof is 180-290 mm. The diameters of the larger (1) and the smaller (2) grooves are 0.8-2.0 mm and 0.4-0.8 mm respectively. One of the two pigtail-shaped ends has only the smaller groove (2) side, without the larger groove (1) side. The special open H-shaped structure can prevent blockage due to urine crystals when draining urine, so that the urine can be drained into bladder smoothly.

The invention discloses a simple urine leakage prevention water bag valve urethral catheter, which belongs to a medical instrument. According to the urethral catheter, a circle of skirt-shaped valve is newly and additionally arranged above a common water bag urethral catheter water bag to realize leakage prevention. The skirt-shaped valve is shrunk and attached to the urethral catheter water bag part at a production stage by means of a special process or adhesion action; after the urethral catheter is determined to enter the bladder in use, water is injected from a water injection port of the water bag, and the skirt-shaped valve is expanded along with water injection of the water bag to be opened and be separated from the original water bag; the skirt valve is attached to the neck of the bladder by means of pressure of the water bag and internal pressure of the bladder just like a piece of thin film covering the water outlet; no matter whether the urethral catheter is closely attached to the urethra, the skirt valve has a seepage blocking effect on the neck of the bladder; and even if the bladder of a patient is actively or non-actively (stimulated) shrunk, the valve is more closely pressed around the neck of the bladder when the pressure of the bladder increases, no dead space exists, the seepage of urine around the urethral catheter can be effectively prevented, and reverse infection is prevented. The urethral catheter is easy and convenient to operate; and compared with the conventional urine catheterization, the workload is not increased.
