Hi, My brother has just had laser surgery for kidney stones under general anaesthetic & has a stent fitted for 5 - 6 weeks. He has cerebal palsy located mainly in his groin so finds it very difficult to get to the toilet quickly & get comfortable as his legs are very stiff & unbending. He now has an infection & has started with antibiotics today. He has a lot of pain at the end of his penis & is generally in a bad way. Is there anything you can suggest to alleviate his pain - he is already taking paracetamol. Is there any diet that can help him with the infection & going forward as he has been told he makes too much calcium in his body which causes these kidney stones. This is the second time he has had this operation (previously it was on his left kidney - this is his right one) & he didn t experience so much pain. The stones this time were large & took some time to laser. He has to go back for the same operation in the near future (still awaiting date) to find out if the operation worked, take out the stent & see if there are any more stones that need attacking. This means he will have to go through all this again & there is nothing I can do to help him. Any help or suggestions you can offer will be most appreciated. Kind regardsm Lita

HelloThanks for query. I feel very sorry for suffering from your brother who is already crippled. The pain in penis and while urinating is due to presence of stent and is common due to irritation of Trig one of the bladder in addition to foreign body reaction to stent. Normally it fades away once the stent is removed. As regards the second planned surgery in few weeks time it will not be so difficult like first surgery as Ureter is widely dilate due to stent making it very simple and easy to fragment the residual stone (if any).In the meanwhile continue giving him appropriate antibiotics and ensure he Chat Doctor. As regards, he's getting recurrence of stone you need to get stone analysis done to know the composition of the stone so that certain dietary measures can be taken to prevent recurrence of stone.
