Kenzi Quinn spends 11 hours each day on dialysis machines

Kenzi Quinn, three, from Sunderland, suffers from polycystic kidney disease and had both kidneys removed last year.

Her father Preston is ready to donate a kidney to keep her alive but the family has discovered that other daughter Kori, two, has the same condition.

Mr Quinn is now appealing for people to sign up to the organ donor register.

In polycystic kidney disease, fluid-filled cysts develop and gradually replace the normal kidney tissue making them less able to function and eventually the kidneys fail completely.

Kenzi spends 11 hours a day hooked up to a dialysis machine.

Mr Quinn said Kori's condition is currently controlled by medication and the main concern for him and partner Gillian Graham, the girls' mother, is for Kenzi who has no kidneys.

He said that many people would have been tested in the past to see if they were a match when their own family members needed a kidney donor.

He said: "If you weren't a match, why not be a live donor for other children in the same situation as Kenzi and Kori?"

Ms Graham said: "I go into a room and scream and let the tears fall when no-one is there.
