Ureteral stent Ureteral stent (detail) 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 ...
The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral.Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic.
The presence of indwelling ureteral stents may cause minimal to moderate discomfort, frequency or urgency incontinence, and infection, which in general resolves on removal. Most ureteral stents can be removed cystoscopically during an office visit under topical anesthesia after resolution of urolithiasis. [116]
Ureteral stents are used for various purposes, such as temporary measures to prevent damage to a blocked kidney until a stone removal procedure can be performed, providing drainage for compressed ureters caused by tumors, and preventing spasms and collapse of the ureter after trauma during procedures like stone removal. The thread attached to ...
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.
Obstruction of the ureter most commonly occurs at the site where the ureters are reconnected to the urinary diversion created. A small, hollow, flexible tube called a stent may be placed inside the ureter at the time of surgery to possibly help the reconnection site to heal. This reconnection site is also at risk for leaking urine within the ...
Alonso was given IV painkillers and sent home with pain pills to take while she waited for the kidney stone to work its way out of her system. Kidney stones are one of the most painful conditions ...
Mean follow-up was 6.5 years. Complications include common ureteral narrowing (one patient); subsequent kidney removal, or nephrectomy (one patient); recurrence of disease with ureteral obstruction (one patient); and disease progression in a case of inflammation of blood vessels, or vasculitis (one patient).
