Trigonoureterosigmoanastomosis

Trigonoureterosigmoanastomosis: what is it and what is it used for?

Trigonoureterosigmoanastomosis is a surgical procedure used to treat various diseases of the urinary system, such as ureteral strictures and some cases of urinary tract obstruction. It consists of creating an anastomosis between the ureter and the sigmoid colon, passing through the vesical triangle.

The ureter is the tube that drains urine from the kidneys to the bladder. The sigmoid colon is the last section of the large intestine that ends in the rectum. Surgical anastomosis is the joining of two different organs or tissues.

A trigonoureterosigmoanastomosis procedure may be necessary when the urinary tract becomes diseased and an obstruction in the ureter needs to be bypassed. This can happen, for example, if there is a ureteral stricture, a narrow place that prevents the passage of urine. The procedure may also be necessary in cases where the ureter or bladder is damaged and a new path for urine needs to be created.

The trigonoureterosigmoanastomosis procedure can be performed either as an open procedure or through laparoscopic surgery. After surgery, the patient may require bladder catheterization for several weeks to ensure normal urine flow.

Although trigonoureterosigmoanastomosis can be an effective way to treat urinary tract problems, it can also lead to some complications such as urinary tract infections, bleeding, and bladder dysfunction.

In general, trigonoureterosigmoanastomosis is a surgical procedure that may be necessary to treat various diseases of the urinary system. This is a complex procedure that must be performed by an experienced surgeon, and the patient may require time to recover from surgery. However, for some patients, this may be the only treatment for their condition and they may benefit significantly from the procedure.

TRIGONOURETHOROSYGMOANASTOMOSIS is a two-stage operation for bladder outlet obstruction. Surgical intervention involves ligation of the ureteral segment at the point of entry into the bladder between the urethra and the vesicoureteral segment, followed by an anastomosis (reciprocal or graft) between the ureteric and sigmoid colon segments.

The use of this operation is indicated for a number of pathological conditions, for example, with fibrosis, benign strictures, to eliminate obstructive paraurethral cystic fibrosis or stenosis in the terminal ureter. In some cases, anastomosis is performed with reimplantation of the ureter with epicystostomy. The procedure can also be used to displace a kidney that is located distal to the ureter or in combination with ureteral stenting for stenosis due to osteochondrosis.
