It's a common enough surgery but most doctors will try other routes before opting for surgery. It was considered for me because I have kidney stones (yes a common condition but many people go through life without them) and my doctor wanted to do imaging first to see how embedded they were and if they were likely to remain so. I never did have the surgery but passed small stones and was treated medicinally for a while. I think you'd have more responses on a renal health forum than here where it would be a random part of the population that this may apply to as opposed to the majority. The anesthesiologist usually determines the drugs used just prior to the procedure or following the pre-op intake. The doctor determines the meds you will go home on and they vary widely depending on their own personal preference, how pressured they are by insurance/DEA, and your personal history. It could be anything from anti inflammatories to strong analgesics/narcotics. It could also be advice for OTC meds. Depends on a lot of things. Ask your doctor in advance if you're concerned about it.
