Minimally invasive surgeries for kidney stones may last as little as four or five days in the hospital or as long as two weeks or more, depending on the type of surgery. Surgical treatment of kidney stones requires different surgical methods due to the different sizes and complexity of the stones, and some patients even need multiple surgeries. If ureteroscopic surgery is performed, the general hospitalization period is about one week and the patient can be discharged from the hospital, but if the stone is complicated by infection and other complications, the hospitalization period will be extended. Complex kidney stones, such as antler stones, require percutaneous nephrolithotomy, and may even require two or three or more surgeries to remove the stone, and the hospitalization days usually take more than two weeks. Therefore, the number of hospitalization days depends on the condition.
