Duplex kidney
Duplex Kidney
Duplex kidney (pronunciation: /ˈdjuːplɛks ˈkɪdni/), also known as a duplicated renal collecting system, is a congenital condition where a kidney has two ureters instead of one. The condition can occur in one or both kidneys.
Etymology
The term "duplex" is derived from the Latin word "duplex", meaning "double". The term "kidney" is derived from the Old English word "cwið", meaning "stomach".
Anatomy
In a normal kidney, a single ureter drains urine into the bladder. However, in a duplex kidney, two ureters drain urine from the kidney into the bladder. This can occur in two ways:
- Complete Duplex System: Each ureter has its own separate connection to the bladder.
- Incomplete Duplex System: The two ureters join together before reaching the bladder, forming a Y shape.
Symptoms
Most individuals with a duplex kidney do not experience any symptoms and the condition is often discovered during imaging tests for other reasons. However, some individuals may experience urinary tract infections, kidney stones, or urinary incontinence.
Diagnosis
Duplex kidney is typically diagnosed through imaging tests such as ultrasound, CT scan, or MRI. A DMSA scan may also be used to assess the function of each part of the duplex kidney.
Treatment
Treatment for duplex kidney is typically not necessary unless the individual is experiencing symptoms. In cases where symptoms are present, treatment may include antibiotics for urinary tract infections or surgery to correct any structural abnormalities.
