What is a duplex kidney?
Duplex kidney is a condition you're born with (congenital) where you have two ureters (tubes) — instead of one — that connect one of your kidneys to your bladder.
It happens early in development, while your kidneys and ureters are forming. Duplex kidney is also called duplicated ureters or duplicated collecting system.
How it works: Ureters are tubes that drain pee (urine) from your kidneys to your bladder. Normally, one ureter leads separately from each of your two kidneys to your bladder. In duplicated collecting systems, two ureters — one in the upper part and one in the lower part — drain a single kidney.
Types of duplex kidney
Kidney duplication may affect one or both kidneys (bilateral duplex kidneys). It can also be complete or incomplete.
Complete Duplex Kidney
Two separate ureters lead away from the same kidney and enter your bladder separately.
Incomplete Duplex Kidney
Two separate ureters lead away from the same kidney but join together before draining into your bladder. This forms a single ureter when it enters your bladder.
Symptoms and Causes
What are the symptoms of duplex kidney (duplicated ureters)?
For most people, duplex kidneys don't cause symptoms. Symptoms happen when the ureters don't drain normally into your bladder (more common with complete duplex kidneys).
Symptoms of duplex kidney complications include:
- Urinary tract infections (UTIs)
- Kidney infections (UTI with fever)
- Leaking pee (urinary incontinence) even after potty training
What causes duplex kidneys?
When a fetus is developing, cell division errors can cause a duplex kidney. There's no evidence that anything you do or don't do during pregnancy causes duplex kidneys.
Is duplex kidney inherited?
Yes, sometimes duplex kidney can be inherited (if a parent has it, their child might have it, as well). If one parent has a duplex kidney, any biological children have a 50% chance of being born with it. But kids can have a duplex kidney even if neither of their parents has the condition.
What are the complications of duplex kidneys?
Duplex kidneys usually cause symptoms only when you have other, related differences in the way your urinary system develops. These differences can lead to blockage of the flow of pee (causing it to build up), swelling (hydronephrosis) and/or pee flowing backwards toward your kidneys (reflux). Any of these conditions can lead to repeated UTIs.
Conditions associated with duplex kidney include:
- Ureterocele
- Ectopic ureter
- Vesicoureteral reflux
- Hydronephrosis
Diagnosis and Tests
What tests will be done to diagnose this condition?
Your provider might perform the following imaging tests to diagnose a duplex kidney:
Ultrasound
Of your kidneys and bladder
CT Scan
Computed tomography scan
MRI
Magnetic resonance imaging
Retrograde Pyelogram
Specialized X-ray test
