Minimally invasive surgery for bladder stones primarily involves performing a holmium laser lithotripsy through a ureteroscope via the urethra. During the procedure, some of the fragmented stones are flushed out of the body. After the surgery, a urinary catheter is installed to assist with urination. On the first day after surgery, patients are not allowed to eat due to the effects of anesthesia. On the second day, patients can consume a light liquid diet. In terms of care, it is important to monitor whether the urinary catheter is clear and unobstructed.
