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 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]
Treatment of ureteric strictures varies from one patient to another depending on the level, cause and extent of stricture in addition to patient factors such as comorbidities and preferences. Treatment options include minimally invasive palliative procedures such as Nephrostomy tube insertion or ureteric stents insertion or ureteral balloon ...
A prostatic stent is a stent used to keep open the male urethra and allow the passing of urine in cases of prostatic obstruction and lower urinary tract symptoms (LUTS). Prostatic obstruction [ 1 ] is a common condition with a variety of causes.
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 ...
Patients can also be treated with alpha blockers [7] in cases where the stone is located in the ureter. A 2019 review found three cases of renal colic were hydronephrosis caused by malpositioned menstrual cups pressing on a ureter. When the cups were removed, the symptoms disappeared. [8]
Mechanical: any structural abnormalities in the urinary tract, vesicoureteral reflux (urine from the bladder flowing back into the ureter), kidney stones, urinary tract catheterization, ureteral stents or drainage procedures (e.g., nephrostomy), pregnancy, neurogenic bladder (e.g., due to spinal cord damage, spina bifida or multiple sclerosis ...
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.
