What is calculus of Ureterovesical Junction?

What is calculus of Ureterovesical Junction?

Ureteric calculi or stones are those lying within the ureter, at any point from the ureteropelvic junction (UPJ) to the vesicoureteric junction (VUJ). They are the classic cause of renal colic-type abdominal pain. They are a subtype of the broader pathology of urolithiasis.

How is ureteral vesicle junction stone treated?

The mainstay treatment for UVJ obstruction is a surgical procedure called ureteral reimplantation. In this surgery, the abnormal part of the ureter that connects to the bladder is removed. The rest of the ureter is then reconnected to another part of the bladder.

How do you treat ureter calculus?

How are ureter stones treated?

  1. Ureteral stent placement. A small, soft, plastic tube is passed into the ureter around the stone, allowing urine to bypass the stone.
  2. Nephrostomy tube placement.
  3. Shock wave lithotripsy.
  4. Ureteroscopy.
  5. Percutaneous nephrolithotomy.
  6. Medical expulsive therapy.

What is the purpose of Ureterovesical Junction?

Background: The valve function of the ureterovesical-junction (UVJ) is responsible for protection of the low pressure upper urinary tract from the refluxing of urine from the bladder.

What is right ureteric calculus?

Ureterolithiasis or ureteric calculi are stones that form in or travel down to the ureters, which are the slender muscular tubes that connect the kidneys to the urinary bladder.

Can ureter stone damage kidneys?

Ureteral obstructions are fairly common blockages that can happen in one or both of your ureters. The ureters are tubes that carry urine from the kidneys to bladder. Untreated blockages can damage your kidneys and put you at risk of infection.

What is calculus in human body?

Calculus, renal: A stone in the kidney (or lower down in the urinary tract). Also called a kidney stone. The stones themselves are called renal caluli. The word “calculus” (plural: calculi) is the Latin word for pebble. Renal stones are a common cause of blood in the urine and pain in the abdomen, flank, or groin.

How are calculi formed in the ureterovesical junction?

Calculi in the ureterovesical junction may also cause irritative voiding symptoms such as dysuria and urinary frequency. Up to 80% of renal calculi are formed by calcium stones 3. Other types include struvite, uric acid and cystine stones.

Where is the ureterovesical junction in the kidney?

The ureterovesical junction is located where the ureter (the tube that drains urine from the kidney) meets the bladder. Ureterovesical junction (UVJ) obstruction refers to a blockage to this area.

How big is the calculus in the ureter?

Axial images of a CT scan of the abdomen and pelvis, showing a 4 mm calculus in the right distal ureter near the ureterovesical junction causing mild hydronephrosis. Coronal images of a CT scan of the abdomen and pelvis, showing a 4 mm calculus proximal to the ureterovesical junction.

When does an ureterovesical junction ( UVJ ) obstruction occur?

UVJ obstruction usually occurs during fetal development. Most of the time, the blockage is caused when the connection between the ureter and the bladder narrows.
