Kidney Duplex Collecting System
Kidney duplex collecting system. Morphogenesis of duplex kidney. Duplication of the ureters is a common anomaly and is frequently encountered by radiologists. A duplex kidney also known as a duplicated collecting system consists of two ureters each coming from a different kidney.
In a normal urinary tract the ureters are two thin tubes in the abdomen one each connecting a kidney to the bladder. What is a duplex collecting system. Children with a duplex kidney also called a duplicated collecting system have two ureters coming from a single kidney.
The part of the kidney that is duplicated is usually the collecting system or renal pelvis which is where urine collects before it is. Duplex collecting systems are one of the most common congenital anomalies with an incidence of 08. Incomplete duplication is most often associated with ureteroureteral reflux or ureteropelvic junction obstruction of the lower pole of the kidney.
Duplex system is explained as the kidney with two pyelocaliceal systems which may have either single or bifid ureter partial duplication or double ureter draining separately into the urinary bladder complete duplication with a single renal parenchyma that is drained by two pyelocaliceal systems - duplex ureters are two ureters from one kidney site could be a bifid ureter Y shaped ureter or two separately. The incidence of duplex kidney is approximately 1. Duplex kidney also known as duplicated ureters or duplicated collecting system is the most common birth defect related to the urinary tract.
Duplex kidney also called duplicated renal collecting system is a developmental condition in which one or both kidneys have two ureter tubes to drain urine into the bladder rather than a single tube. Subsequently apoptosis of the common nephric duct CND leads to the insertion of both ureters into the developing bladder with the orifice of the initially posteriorly positioned ureteric bud ending up in a superior position. The 2 ureters empty separately into the bladder or fuse to form a single ureteral orifice.
A duplex collecting system is a congenital kidney anomaly with an incidence of 08. A duplex collecting system or duplicated collecting system is one of the most common congenital renal tract abnormalities. Duplication may be either complete or incomplete and is often accompanied by various complications.
It is possible to connect and drain both ureters separately into the bladder or to connect and drain both ureters together. It is possible for one or both kidneys to function simultaneously.
When a duplex collecting system is present two ureters one draining the upper part of a kidney-the other draining the lower half connect each.
Incomplete duplication is most often associated with ureteroureteral reflux or ureteropelvic junction obstruction of the lower pole of the kidney. In these cases the double collecting system is thought to result from duplication of the ureteric bud. A normal urinary tract includes two kidneys each with a ureter that drains urine into the bladder.

A duplex kidney also known as a duplicated collecting system consists of two ureters each coming from a different kidney. A duplex kidney also known as a duplicated collecting system consists of two ureters each coming from a different kidney. Duplicated collecting systems also known as duplex collecting systems can be defined as renal units containing 2 pyelocaliceal systems that are associated with a single ureter or with double ureters. Duplex kidneys can occur in one or both kidneys.
