Megaureter

Megaureter is a significant dilation of the ureter. It is formed directly above the site of long-term obstruction of the ureter, as a result of which the free outflow of urine from the renal pelvis is obstructed in this place.

The most typical cause of the formation of a megaureter is the reflux of urine from the bladder back into the ureters (see Vesico-ureteral reflux), however, along with this cause, there are examples of the formation of the so-called idiopathic megaureter. In this case, either one or both ureters may be affected; in this case, at the very bottom of the bladder there is a segment of a normal ureter, which can be of varying length, and the ureter located above it expands significantly.

In both cases (with both urine reflux and idipathic megaureter), the patient's condition worsens, leading to the development of urinary tract infections and/or renal failure. During the treatment process, corrective surgery is performed.



Megaureter is a significant dilation of the ureters that can lead to serious urinary tract diseases. The most common cause of megaureter development is obstruction of the ureter due to reflux of urine from the bladder into the urinary tract. However, there are other causes, such as idiopathic megaureter, in which the ureters may dilate without obvious cause.

Megaureter affects the functioning of the kidneys and urinary tract, which can lead to the development of urinary tract infections, kidney failure and other complications. Treatment for megaureter usually involves corrective surgery, which may involve removing the dilated portion of the ureter or restoring its patency.

It is important to note that megaureter can be detected at any age, and early detection and treatment can help prevent the development of serious complications. Therefore, if you notice any changes in your urinary tract or kidney function, consult your doctor for diagnosis and treatment.
