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.
Newer treatments can include the placement of a stent and is usually successful. In 0.5-2.5% of major pelvic surgeries a ureterovaginal fistula will form, usually weeks later. [ 2 ] If the fistula cannot be repaired, the clinician may create a permanent diversion of urine or urostomy . [ 6 ]
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.
A ureteric balloon catheter is a balloon catheter intended for treating strictures of the ureter. In fact it is a double J stent on which a balloon is mounted. It is connected to a delivery device (pusher) to introduce it from the bladder into the ureter. The system comprises a non-return valve device, and a pusher with a stylet and two ports.
Ureterovesicular junction obstruction (UVJ obstruction) is an obstruction at the level of the ureter and bladder. It accounts for 20% of cases of hydronephrosis detected in utero. It is also most commonly seen in males and involved both sides of the urinary tract in approximately 25% of cases. [1]

A friend referred to her toddlers as anchors: cute, squishy anchors, but anchors nonetheless. The same could be said of our pets — furry, feathered, and finned. We love them dearly and can’t ...
Ureteral stent exchange: indwelling double-J type ureteral stents, typically placed by urologist using cystoscopy, may be exchanged in retrograde fashion through the female urethra. The IR uses a thin wire snare under fluoroscopy to capture the distal portion of the stent.
