Ureteral stones are usually caused by kidney stones that obstruct the narrowing of the ureter during the process of expulsion. Characteristics: It is often accompanied by severe lumbar and abdominal pain, hematuria, nausea and vomiting. After the acute phase of symptoms (usually 2-3 days), the pain often gradually relieves, but the still undischarged stones can still cause ureteral obstruction and hydronephrosis, eventually causing renal insufficiency or even uremia. Therefore, the treatment of ureteral stones cannot be judged by the presence or absence of painful symptoms, but must follow the doctor’s instructions for regular review to ensure the discharge of stones. Treatment plan: Ureteral stones should be determined according to the location of the stones, the time of onset, the size of the stones and other factors. 1.Medication: stones with onset within half a month and diameter less than 0.6 cm. 2.Extracorporeal shock wave lithotripsy: stones with onset within half a month, diameter less than 2.0 cm, not in the pelvis (upper or lower part of the ureter). 3.Ureteroscopic lithotripsy: currently the main minimally invasive treatment, with the best effect on stones with a long history and located in the middle or lower part of the ureter. 4.Open surgery: it is basically eliminated at present, and is only applicable to patients with urinary system deformities and unable to undergo minimally invasive treatment.
