General anesthesia is normally used for kidney stone surgery, although sedation may be used for shock wave lithotripsy.
If you’re having a general anesthetic, ask your surgeon if you can meet with the anesthetist before the day of the procedure. This way you won’t be hurried or stressed and can be involved in the planning.
Sedation
Sedation will make you feel sleepy and relaxed. It reduces your awareness of the surgery and any discomfort. The anesthetist will normally give you sedation into a vein.
Pre-medication
The anesthetist may offer you medication before the surgery. This could be to prevent nausea, reduce stomach acid, or help you relax. If you think you’ll be feeling anxious before surgery, ask if you can have something to relax you.
General anaesthetic
With a general anaesthetic, you’ll be unconscious for your procedure and a tube will be inserted into your throat to help you breathe. You may wake up with a sore throat from the tube. General anesthetics may cause post-operative nausea and vomiting. Inform your anaesthetist if this has happened to you in the past as there are ways to help prevent it.  You may also get a local anesthetic for your wound.
If you’re overweight or obese, there are increased risks associated with general anesthesia.
Pain relief after surgery
After surgery, you’ll be given pain relief prescribed by your anesthetist.
Pills, tablets, or liquids can be given at regular times or when pain starts to bother you.
