Duplex kidney
中文译名：重复肾
The world ‘duplex’ is Latin for ‘double’ so having a duplex kidney literally means that your child has a double kidney on one side. Some of our patients at Great Ormond Street Hospital who have this condition are proud to boast that they have three kidneys!
The double section is usually limited to the part of the kidney where the urine collects (the collecting system or renal pelvis), before the urine passes down the bladder in the usual way via a tube called the ureter.
