Congenital primary megaureter, refluxing form

Congenital primary megaureter, refluxing form, is a condition present from birth in which one or both ureters (the tubes that carry urine from the kidneys to the bladder) are abnormally wide (dilated). In the refluxing form, urine flows backward from the bladder up toward the kidneys, a problem known as vesicoureteral reflux (VUR). This happens because the connection between the ureter and the bladder does not work properly, allowing urine to travel in the wrong direction. The condition is often detected before birth on prenatal ultrasound or in early infancy when a child develops urinary tract infections. Key symptoms include recurrent urinary tract infections, flank or abdominal pain, and in some cases, poor kidney growth or kidney damage if the reflux is severe and left untreated. Some children may have no obvious symptoms, and the condition is discovered incidentally during imaging studies. Boys are affected more often than girls, and the condition can occur on one or both sides. Treatment depends on the severity. Many mild cases resolve on their own as the child grows, and doctors may recommend a watch-and-wait approach with preventive low-dose antibiotics to reduce urinary tract infections. More severe cases, especially those causing kidney damage or recurrent infections despite antibiotics, may require surgical correction. The most common surgery is ureteral reimplantation, where the ureter is repositioned into the bladder to prevent reflux. Endoscopic injection therapy is another less invasive option. With appropriate monitoring and treatment, most children have an excellent long-term outcome.
