Ureterostomy
A ureterostomy is the creation of a 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, a reddish, moist abdominal protrusion. The ileal conduit is not painful; it has no sensation. The ureterostomy stoma retains sensation. Since it has no muscles to regulate u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ureteroureterostomy
Ureteroureterostomy ( "urétero-uréte-róstomy") is end-to-end connection (anastomosis) of the two portions of a transected ureter; also called ureteroureteral anastomosis An anastomosis (, plural 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 ... 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".

Stoma (medicine)
In anatomy, a stoma (plural stomata or stomas) is any opening in the body. For example, a mouth, a nose, and an anus are natural stomata. Any hollow organ can be manipulated into an artificial stoma as necessary. This includes the esophagus, stomach, duodenum, ileum, colon, pleural cavity, ureters, urinary bladder, and renal pelvis. Such a stoma may be permanent or temporary. Surgical procedures that involve the creation of an artificial stoma have names that typically end with the suffix "-ostomy", and the same names are also often used to refer to the stoma thus created. For example, the word "colostomy" often refers either to an artificial anus or the procedure that creates one. Accordingly, it is not unusual for a stoma to be called an ostomy (plural ostomies), as is the norm in wound, ostomy, and continence nursing. Gastrointestinal stomata Stomata are created in particular in surgical procedures involving the gastrointestinal tract (GIT) or gastrointestinal system (GI ...

List Of Surgeries By Type
Many surgical procedure names can be broken into parts to indicate the meaning. For example, in gastrectomy, "ectomy" is a suffix meaning the removal of a part of the body. "Gastro-" means stomach. Thus, ''gastrectomy'' refers to the surgical removal of the stomach (or sections thereof). "Otomy" means cutting into a part of the body; a ''gastrotomy'' would be cutting into, but not necessarily removing, the stomach. And also "pharyngo" means pharynx, "laryngo" means larynx, "esophag" means esophagus. Thus, "pharyngolaryngoesophagectomy" refers to the surgical removal of the three. The field of minimally invasive surgery has spawned another set of words, such as ''arthroscopic'' or ''laparoscopic'' surgery. These take the same form as above; an arthroscope is a device which allows the inside of the joint to be seen. List of common surgery terms Prefixes * ''mono-'' : one, from the Greek μόνος, ''monos'', "only, single" * ''angio-'' : related to a blood vessel, from the G ...

Ureter
The ureters are tubes made of smooth muscle that propel urine from the kidneys to the urinary bladder. In a human adult, the ureters are usually long and around in diameter. The ureter is lined by urothelial cells, a type of transitional epithelium, and has an additional smooth muscle layer that assists with peristalsis in its lowest third. 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 least the time of Hippocrates. It is, ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kidney
The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney ...

Cystostomy
A suprapubic cystostomy or suprapubic catheter (SPC) (also known as a vesicostomy or epicystostomy) is a surgically created connection between the urinary bladder and the skin used to drain urine from the bladder in individuals with obstruction of normal urinary flow. The connection does not go through the abdominal cavity. Urinary flow may be blocked by swelling of the prostate (benign prostatic hypertrophy), traumatic disruption of the urethra, congenital defects of the urinary tract, or by obstructions such as kidney stones passed into the urethra, and cancer. It is also a common treatment used among spinal cord injury patients who are unable or unwilling to use intermittent catheterization to empty the bladder, and cannot otherwise void due to detrusor sphincter dyssynergia. Initially, a thin tube (catheter) is placed through the skin just above the pubic bone into the bladder, often with the assistance of ultrasound imaging. This catheter initially remains in place for up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Percutaneous Nephrostomy
{{More citations needed, date=January 2021 In surgery, a percutaneous procedurei.e. Granger et al., 2012 is any medical procedure or method where access to inner organs or other tissue is done via needle-puncture of the skin, rather than by using an "open" approach where inner organs or tissue are exposed (typically with the use of a scalpel). The percutaneous approach is commonly used in vascular procedures such as angioplasty and stenting. This involves a needle catheter getting access to a blood vessel, followed by the introduction of a wire through the lumen (pathway) of the needle. It is over this wire that other catheters can be placed into the blood vessel. This technique is known as the modified Seldinger technique. More generally, "percutaneous", via its Latin roots means, 'by way of the skin'. An example would be percutaneous drug absorption from topical medications. More often, percutaneous is typically used in reference to placement of medical devices using a need ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
