Early detection of duplex kidney either on ultrasound or intravenous pyelography is very important because that will help to monitor patient for development of complications associated with duplex kidney especially urothelial malignancy at early stage in order to make nephron sparing surgery favorable for patient with surgical removal of tumor and cure of patient.
During routine clinical procedures, urine culture, voided urine cytology, abdominal ultrasonography (USG), intravenous pyelography (IVP) and computerized tomography are used in the initial diagnosis and follow-up.
Although it is currently unclear whether early diagnosis and treatment will result in a better prognosis, it has been suggested that hemoglobin electrophoresis, intravenous pyelography, and CT scans should be the minimal studies performed in young, black patients with hematuria.
It is also interesting to note that nearly all institutions require informed consent documentation for angiography, but only a little more than half require informed consent for intravenous pyelography.
Imaging of urinary tract that include renal USG, micturating cystourethrography (MCU), 99mTc-dimercaptosuccinic acid scintigraphy (DMSA) and in some cases Ethylene dicysteine renal scan (EC renal scan), 99mTc-diethylenetriaminepentaacetic acid scan (DTPA scan) and Intravenous pyelography (IVP) were done whenever relevant as per protocol recommended by Indian Paediatric Nephrology Group.
