It is an invasive operation that requires puncture from the skin to the kidney, and there is a risk of bleeding and infection, especially after strenuous exercise, so it is important to avoid strenuous exercise, such as intercourse, after kidney puncture. Generally, the puncture wound and kidney tissue may heal after 1 month or more, and it is relatively safer after 2 months, so it is recommended to have intercourse after 2 months after kidney puncture, and we must pay attention to the specific situation, if there are obvious discomfort symptoms during intercourse, it should be stopped in time, if there is no obvious discomfort, it should not be a big problem.
