Renal scintigraphy: Renal scintigraphy enables the separate determination of renal function of the upper and lower part of the duplex kidney for further treatment planning.

Some cases have been reported on bilateral duplex collecting system [4, 5]. A duplex collecting system often causes no symptoms and may only be noticed during pregnancy when routine ultrasound examination shows fetal hydronephrosis.

After birth, urinary tract infections and/or day/nighttime wetting, or flank pain may be presenting signs/symptoms. There are not much data about it.

Ureters are long, narrow tubes that drain urine from the kidneys to the urinary bladder. Children with a duplex kidney (also called a duplicated collecting system) have two ureters coming from a single kidney. Duplicated ureter or Duplex Collecting System is a congenital condition in which the ureteric bud, the embryological origin of the ureter, splits (or arises twice), resulting in two ureters draining a single kidney.It is the most common renal abnormality, occurring in approximately 1% of the population.

The additional ureter may result in a ureterocele, or an ectopic ureter Duplex-system. A duplex collecting system, or duplicated collecting system, is one of the most common congenital renal tract abnormalities. The more extensive duplication, however, does often cause problems and can typically mean a child is more prone to urine infections. What are duplex collecting system care options? The limited duplex kidney (where only the collecting system is double) is usually an incidental finding and rarely causes problems. If needed, treatments include: Nephrectomy: Some or all of a kidney that is not working correctly is surgically removed.

Cystoscopy: Cystoscopy and retrograde pyelography is necessary depending on complaints. However, after birth, treatment will depend on how the duplication of collecting systems is affecting the urinary system.

Bilateral duplex collecting system is a rare abnormality. In 2001, the US Food and Drug Administration (FDA) approved the use of dextranomer/hyaluronic acid as the first FDA-approved subepithelial injectable treatment for VUR in the USA .
This surgery should be used only when kidney function is poor and the other kidney is operating normally. One ureter drains the upper part of the kidney and the other drains the lower part.

A duplex collecting system often causes no symptoms and may only be noticed during pregnancy when routine ultrasound examination shows fetal hydronephrosis. Duplicated collecting system; two ureters. Duplex kidneys can occur in one or both kidneys.

Treatment of the Duplex Kidney Hydronephrosis is a condition that typically occurs when one kidney swells due to urine failing to drain properly from the kidney to the bladder. This will eliminate incontinence and decrease the chance of infection. Duplex kidney, also called duplicated collecting system, occurs in about 1 percent of children and usually requires no medical treatment. Effectiveness of primary endoscopic incision in treatment of ectopic ureterocele associated with duplex system.

Finally, we may note that a bilateral duplex collecting system with refluxing upper pole ureter is rare. Ectopic (extravesical) Orifice is located in bladder neck, urethra A duplex collecting system, or duplicated collecting system, is one of the most common congenital renal tract abnormalities.

In many cases, a duplex collecting system does not require treatment… Most do not need treatment.

Duplex kidney is a developmental condition in which one or both kidneys have two ureter tubes to drain urine, rather than a single tube. Single kidney; single collecting system; single ureter. Urology. Surgical approaches can be either open or laparoscopic, with laparoscopic gaining more favour except in complicated cases such as in our patient. A duplex collecting system and ureterocele are generally treated in tandem.
