Patients with stones may suffer from nausea. This is often seen when stones cause acute intrapelvic hypertension and hydronephrosis, which can cause elevated renal peritoneal tension and reflex spasms of the gastrointestinal tract, resulting in nausea and vomiting, so that kidney stones and stones in the upper ureter, except for pain, may be accompanied by gastrointestinal symptoms, which is a relatively common reaction. When the stone is discharged into the lower ureter, the nausea, vomiting and back pain will gradually decrease or disappear. If the stone leaves the obstruction site or is discharged into the ureter after extracorporeal shock wave lithotripsy, the pressure in the renal pelvis will be slightly reduced, so that the symptoms of nausea, vomiting or pain can be relieved to varying degrees. However, for patients with longer obstruction and more severe symptoms, inpatient surgery is necessary to relieve the obstruction and relieve the pain and nausea and vomiting.
