A ureteral stent (pronounced you-REE-ter-ul), or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters.
The exact area is then located by ultrasound. Local anesthetic infiltration is used to numb the area. Then a needle would pass through to make the puncture on the kidney. Then, urine from the kidney is aspirated and check for its contents. If the urine is clear, dye will be injected to delineate the renal pelvis and renal calyx. If the urine is ...
Stenting refers to the placement of a stent. The word "stent" is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologically narrowed a structure such as an artery. A stent is different from a shunt. A shunt is a tube that connects two previously unconnected parts of the ...
The ureteric balloon catheter is intended to cure two major types of diseases: Ureteropelvic junction obstruction (also called UPJ obstruction or Pelvic-ureteric junction obstruction PUJO) [1] caused by intrinsic wall factors as fibrosis and / or hypertrophic wall problems.
A ureteric stent may be inserted to relieve an obstruction. [16] If the cause cannot be removed, a nephrostomy may be required, which is the insertion of a tube connected to the renal pelvis which directly drains urine into a stoma bag. [17]
A retrograde pyelogram may be performed to find the cause of blood in the urine, or to locate the position of a stone or narrowing, tumour or clot, as an adjunct during the placement of ureteral stents. [13] It can also be used ureteroscopy, or to delineate renal anatomy in preparation for surgery.

Left sided hydronephrosis in a person with an atrophic right kidney. Stent is also present (image below). Left sided hydronephrosis, coronal view. Stent is also present. Treatment of hydronephrosis focuses on the removal of the obstruction and drainage of the urine that has accumulated behind the obstruction.
