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.
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 ...
Leaking: Leakage of urine may occur from the stoma, particularly if the channel becomes stretched and the valve preventing such leaks fails to self- seal. [5] Bladder spasms, painful contractions of the bladder, can cause leakage from the stoma or the urethra [ 30 ] and may need to be treated with medication called an antispasmodic.
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]
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.
Percutaneous coronary intervention (coronary angioplasty with stent placement): A percutaneous coronary intervention involves opening up a narrowed artery in your heart with a thin tube called a ...
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).
Nephrectomy for renal cell carcinoma is rapidly being modified to allow partial removal of the kidney. Nephrectomy is also performed for the purpose of living donor kidney transplantation. [1] A nephroureterectomy is the removal of a kidney and the entire ureter and a small cuff of the bladder for urothelial cancer of the kidney or ureter. [9]
