Last Wednesday morning, James and I went into theatre at the Royal Free hospital in Hampstead to undergo transplant surgery. My left kidney was removed from me and transplanted in to James, who has renal failure.

The operation itself went very well and my kidney began working as soon as it was connected up to James on the operating table.

We both came round a bit sore and tired, but completely overjoyed that litres of urine were gushing out of James's catheter thanks to my kidney, beavering away inside him as if nothing had happened.

But unfortunately, there were complications after the surgery. James suffered lots of internal bleeding, which caused other problems internally and he became very sick. I have to admit, I didn't think he was going to make it. Sunday night was the longest and worst of both our lives.

They took him back into theatre for an operation on Monday to remove the blood clot that had formed around the (my) kidney. The good news is that it is still working perfectly.

James is still very weak and I wouldn't say he's quite out of the woods yet, but things have now turned the corner for the better.

I am absolutely fine - still a little sore and tired, but relieved the worst seems to have passed.

So, fingers crossed, we might yet pull this off. We might just get our life back after all.

James hopes to be back writing next week.
