The ureteral stent is placed in the ureter, and the two ends are respectively located in the kidney and the bladder. It is used to support the ureter, connect the kidney and the bladder, and ensure the smooth transportation of urine. Because its two ends resemble the letter "J", it is also called DJ tube, double J tube or pigtail tube, and is widely used in urological surgery.
Four functions of ureteral stent
Drainage: The ureteral stent is a hollow tubular stent that can drain urine, reduce hydronephrosis, and improve kidney function; Especially for patients with long-term ureteral obstruction leading to pyonephrosis, the drainage effect of indwelling ureteral stent is immediate.
Support: When ureteral stones cause urethritis edema, polyp formation, or ureteral edema after endoscopic surgery, the ureteral stent can support the ureter and help the ureteral mucosa repair.
Bridging: Indwelling ureteral stents in ureteral stricture resection or ureteral bladder reimplantation can help to connect the stumps of the ureter, reduce urinary extravasation, and promote the healing of the stumps.
Dilation: Ureteral stents are generally left in the ureter for 1-2 months. During this period, the ureter can be passively expanded to make the lumen thicker for better urination and stone removal.
