Ureterectasis Meaning

Ureterectasis is the enlargement of either the right or left ureter, the fibromuscular tubes that transport urine from the renal pelvis to the bladder. If the flow of urine is obstructed, the ureteral pressure might rise, resulting in dilatation. It is referred to as ureterectasis or hydroureter if only the ureter is dilated. When both the ureter and the kidney get bigger, it is called hydroureteronephrosis or hydronephrosis.

Ureterectasis Definition

The term "ureterectasis" describes an enlargement or dilatation of the ureter, a tube that delivers urine from the kidney to the bladder. This problem can be caused by a variety of circumstances, such as obstructions in the ureter, damage to the ureter as a result of accident or surgery, or underlying medical diseases such as renal disease or urinary tract infections.

Ureterectasis Symptoms

In certain instances, initial symptoms may be very modest, but they may quickly deteriorate into a more severe form. Some of the signs and symptoms are:

  1. Discomfort felt below the rib cage (in the belly, the back, or the sides).
  2. Malaise, sickness, or throwing up
  3. Discomfort or difficulty in passing urine
  4. Frequent urination
  5. UTIs that recur frequently
  6. Having bloody or cloudy urine
  7. Low urine output

Ureterectasis Causes

There are two types of ureterectasis: hereditary and acquired.


The ureteropelvic junction, which connects the ureter to the kidney, can become obstructed due to congenital conditions such as ureteropelvic junction obstruction, which occurs when this section fails to canalize during fetal development.

Vesicoureteral reflux is another genetic condition that causes urine to flow retrograde from the bladder into the ureters and then the kidneys. A posterior urethral valve is a condition in which tissue flaps block the posterior urethra, the portion of the urethra closest to the bladder. This condition is one of several congenital causes.


Ureterectasis can also be caused by kidney stones, an enlarged prostate, or retroperitoneal or pelvic malignancies that impinge on the ureter externally.

Ureterectasis Treatment

The course of treatment you receive is determined by the cause of the blockage. Your doctor will first carry out a procedure to let your body's urine drain. These steps consist of:

  • A ureteral stent is inserted into the ureter to hold the ureter open and allow for unobstructed urine drainage.
  • A nephrostomy, or small incision in the skin around the kidney, is made in this technique to insert a catheter. Direct kidney urine drainage is accomplished by inserting a catheter into the hole.
  • The insertion of a catheter into the urinary bladder is the treatment of choice when the obstruction in question is located at the point where urine exits the bladder.

After the urine has been drained, your doctor will examine the underlying cause of the obstruction. The approach taken by your physician will depend on the origin of the obstruction and the severity of the obstruction.
