Generally speaking, people with two parents suffering from Polycystic Kidney Disease have 75% chance to inherit this kidney disorder. And people with one parent suffering from PKD have 50% chance to undergo this disease. Therefore, children with family members undergoing PKD still have chance to live without being damaged by polycystic kidney problem.
Besides, although PKD is genetic-related, people without family history still have chance to suffer from this problem and it occurs in about 10% of cases. It occurs by a randon mutation in the gene that disposes patients to the disease. At present, nobody knows why this occurs and it is considered to be spontaneous.
For PKD with or with no family history, the diagnosis is based on medical tests such as CT scan, B ultrasound, MRI (Magnetic Resonance Imaging), Routine Urine Test, Routine Blood Test, KUB and IVP (Intravenous Pyelogram) and so on. All these medical tests help to diagnose PKD in different ways and play an important role for PKD patients to learn about their illness condition.
