Den del av urinvägssystemet som sköter transporten, kallas urinvägarna. Hos människan består urinsystemet av två njurar, två urinledare, urinblåsan, urinröret och två slutarmuskler, sfinktrar. Stor del av urinvägarna täcks på insidan av Thereafter, terms "ureter" and "urethra" were variably used to refer to each other thereafter for more than a millennia. It was only in the 1550s that anatomists such as Bartolomeo Eustacchio and Jacques Dubois began to use the terms to specifically and consistently refer to what is in modern English called the ureter and the urethra.

In rats, congenital cases are more prevalent on the right side. Christal G. Pollock DVM, Diplomate ABVP (Avian), in Ferrets, Rabbits, and Rodents (Third Edition), 2012 Hydronephrosis. Hydronephrosis and hydroureter are uncommon findings in ferrets usually attributed to ligation of the ureter during ovariohysterectomy. 46 There have also been rare reports of hydronephrosis associated with obstruction caused by ureteral calculi, carcinoma involving the renal Known medicinal treatments include the use of alpha-blockers such as Flomax that relax the lining of the ureter to help stones pass more easily, and medications that treat the associated pain. Additionally, surgical procedures or other non-invasive means of surgical treatment may be prescribed to break up both calcium oxalate and uric acid kidney stones.
The kidneys collect urine, which empties into two tubes called the ureters, which in turn lead to the bladder. Although cancer of the ureter and/or renal pelvis is rare, when it does occur it affects mainly men, and usually people over the age of 65.
The urinary tract is made up of 2 kidneys, 2 ureters, the bladder, and the urethra. The kidneys act as a filter system for the blood. They remove toxins and keep the useful sugar, salts, and minerals. Urine, the waste product, is made in the kidneys and flows down 2, 10 to 12-inch-long tubes called ureters into the bladder.
Pain, which can be severe, is the most common symptom. Learn more about the other symptoms ureter definition: 1. a tube on each side of the body that takes urine from the kidney to the bladder 2. a tube on….
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.

A ureter is a thin tube that allows urine to travel from the kidney to the bladder. Each ureter is a muscular tube about 8 to 10 inches long. The muscles tighten and relax to force urine down into the bladder, away from the kidneys. The kidneys collect urine, which empties into two tubes called the ureters, which in turn lead to the bladder. Although cancer of the ureter and/or renal pelvis is rare, when it does occur it affects mainly men, and usually people over the age of 65.

Calculi are crystal accumulations and can be caused by inadequate fluid intake, excessive meat consumption, or inflammation. Cell-based tissue engineering offers an alternative technique for urinary tract reconstruction.
