Ureteroureterostomy
Ureteroureterostomy ( "urétero-uréte-róstomy") is end-to-end connection (anastomosis) of the two portions of a transected ureter; also called ureteroureteral anastomosis and van Hook operation (after Weller van Hook, surgeon). __TOC__ Reasons for performing procedure Ureteroureterostomies are often performed because of injured or scarred ureters, especially when the ureter in question is damaged in its upper third section. Generally if the patient has distal uretral strictures (narrowing of the ureter), a ureteroureterostomy is not recommended and a ureter reimplantation would be favorable.http://www.urology-textbook.com/ureteroureterostomy.html "Ureteroureterostomy: End-to-End Anastomosis of the Ureter".

Anastomosis
An anastomosis (, : anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus' heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Greek ana- "up, on, upon", stoma "mouth" ...

Ureter
The ureters are tubes composed of smooth muscle that transport urine from the kidneys to the urinary bladder. In an adult human, the ureters typically measure 20 to 30 centimeters in length and about 3 to 4 millimeters in diameter. They are lined with urothelial cells, a form of transitional epithelium, and feature an extra layer of smooth muscle in the lower third to aid in peristalsis. The ureters can be affected by a number of diseases, including urinary tract infections and kidney stone. is when a ureter is narrowed, due to for example chronic inflammation. Congenital abnormalities that affect the ureters can include the development of two ureters on the same side or abnormally placed ureters. Additionally, reflux of urine from the bladder back up the ureters is a condition commonly seen in children. The ureters have been identified for at least two thousand years, with the word "ureter" stemming from the stem relating to urinating and seen in written records since at ...

Surgeon
In medicine, a surgeon is a medical doctor who performs surgery. Even though there are different traditions in different times and places, a modern surgeon is a licensed physician and received the same medical training as physicians before specializing in surgery. In some countries and jurisdictions, the title of 'surgeon' is restricted to maintain the integrity of the craft group in the medical profession. A specialist regarded as a legally recognized surgeon includes podiatry, dentistry, and veterinary medicine. It is estimated that surgeons perform over 300 million surgical procedures globally each year. History The first person to document a surgery was the 6th century BC Indian physician-surgeon, Sushruta. He specialized in cosmetic plastic surgery and even documented an open rhinoplasty procedure.Papel, Ira D. and Frodel, John (2008) ''Facial Plastic and Reconstructive Surgery''. Thieme Medical Pub.

Stenosis
Stenosis () is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture). ''Stricture'' as a term is usually used when narrowing is caused by contraction of smooth muscle (e.g. achalasia, prinzmetal angina); ''stenosis'' is usually used when narrowing is caused by lesion that reduces the space of lumen (e.g. atherosclerosis). The term coarctation is another synonym, but is commonly used only in the context of aortic coarctation. Restenosis is the recurrence of stenosis after a procedure. Examples Examples of vascular stenotic lesions include: * Intermittent claudication (peripheral artery stenosis) * Angina ( coronary artery stenosis) * Carotid artery stenosis which predispose to (strokes and transient ischaemic episodes) * Renal artery stenosis Types In heart valves The types of stenoses in heart valves are: * Pulmonary valve stenosis, which is th ...

Ureterostomy
A ureterostomy is the creation of a stoma (medicine), stoma (a new, artificial outlet) for a ureter or kidney. The procedure is performed to divert the flow of urine away from the bladder when the bladder is not functioning or has been removed. Indications include bladder cancer, spinal cord injury, malfunction of the bladder, and birth defects such as spina bifida. Types There are two basic types of urostomies. The first features the creation of a passage called an "ileal conduit." In this procedure, the ureters are detached from the bladder and joined to a short length of the small intestine (ileum). The other type of urostomy is cutaneous ureterostomy. With this technique, the surgeon detaches the ureters from the bladder and brings one or both to the surface of the abdomen. The hole created in the abdomen is called a stoma (medicine), stoma, a reddish, moist abdominal protrusion. The ileal conduit is not painful; it has no sensation. The ureterostomy stoma retains sensation. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
