If the kidney stones are causing vomiting, it is recommended to go to the hospital for further treatment. 1. If the examination is due to gastrointestinal reaction caused by kidney stones, it is recommended to inject metoclopramide intramuscularly or push ondansetron intravenously to relieve the vomiting symptoms, and at the same time, it is recommended to carry out extracorporeal shock wave lithotripsy and ureteral stent tube drainage to reduce the pressure in the renal pelvis and reduce the irritation after nausea and vomiting. 2. If the vomiting is not caused by kidney stones but by gastrointestinal diseases, it is recommended to go to the gastroenterology department for further consultation and give symptomatic antiemetic drugs, appropriate rehydration or suppression of gastric acid secretion to reduce the symptoms of vomiting, and then go to the urology department to deal with the stones after the gastrointestinal diseases are stabilized. 3. If the vomiting is caused by water retention in the kidneys caused by stones and azotemia, dialysis treatment is recommended, and the vomiting symptoms can be gradually relieved or disappeared after the urea nitrogen and creatinine levels in the serum have decreased.
