I am booked in for a robotic partial nephrectomy on 1st April. I have a 2.6cm Bosniak 4 cyst. I keep reading that I won't be able to raise my arm above my head and I cannot find any explanation why not? I live alone, it's my right kidney and I'm right handed. I am not going to be able to tie my hair up if I cannot raise my right arm!!! Has anyone had this issue, and how long did it last for you? I am also worried about how I will know if I am damaging my sewn-up kidney. I have a high pain threshhold so I ride with twinges etc but how would I know if, for example, I have damaged my kidney when rolling out of bed?
