Congenital ureteral cyst (ureteral prolapse cyst) is a birth defect of the urinary tract that is quite common in children. If not detected and treated promptly, in the long term, it will cause complications on the kidneys and urinary system such as recurrent urinary infections, ureteral stones, scarring of the kidney leading to impaired kidney function. Therefore, it is necessary to diagnose ureteral cysts early to have timely treatment.

A prolapsed ureteral cyst, also known as a ureteral cyst, is a birth defect that is more common in girls than in boys. It is a bulge in the bladder at the end of the ureter, which can block the flow of urine down the bladder. A prolapsed ureter may be a large bulge or just a small bulge located inside or outside the bladder or down to the bladder neck or urethra. Ureteral prolapse can be diagnosed in the fetus with prenatal diagnostic methods.

Symptoms of ureteral prolapse may include: pain, back pain or abdominal pain; Urinary tract infections: fever, cloudy urine, strong-smelling urine. Urinary disorders: painful urination, dysuria, difficulty urinating.

The most important major complication of ureteral prolapse is damage and infection of the kidney. The prolapsed ureteral sac obstructs urine outflow, causing recurrent urinary tract infections and thus kidney damage and impaired renal function.
Diagnostic methods for ureteral prolapse are ultrasound, cystography, and CT scan.

4.1. Transurethral puncture Usually indicated for prolapsed ureteral sac in the bladder and thin wall. In this way, the prolapsed ureteral sac is punctured or deflated to allow urine to flow easily from the kidney to the bladder.
4.2. In some cases of a double ureteral kidney, when the prolapsed ureteral sac that causes the corresponding upper pole is no longer functional, this part should be removed.
4.3. Nephrectomy In single ureteral nephrology, if ureteral prolapse causes loss of kidney function, nephrectomy will be performed for these cases.

4.4. This is a surgical method to open the bladder, remove the prolapsed sac, and replant the ureter into the bladder wall. This method has a high success rate of about 90-95%.
4.5. Ureteral anastomosis For cases where the upper part of the ureter has a good prolapsed sac and there is no reflux in the lower part, the doctor may use the method of connecting the obstructed part to the non-obstructed part of the ureter or renal pelvis. .
For children with ureteral prolapse causing obstruction or vesicoureteral reflux, antibiotics should be used to prevent urinary tract infections until surgery.

In summary, congenital ureteral cysts, if not examined and treated early, can leave dangerous complications for the kidneys later on. Therefore, early diagnosis and examination of the disease is very important. In particular, ureteral cyst is a disease that can be diagnosed in the fetus, so parents need to follow the advice of specialists.
