Urethral stones are generally divided into posterior urethral stones and anterior urethral stones, whereas ureteral stones are classified into upper, middle, and lower segments. For posterior or anterior urethral stones, the main symptoms include frequent urination, urgent urination, painful urination, a feeling of obstruction during urination, and in severe cases, hematuria or even urinary retention may occur. In such cases, timely lithotripsy and stone removal treatment are required. If the stone is in the lower segment of the ureter and pauses at a certain place, the patient often does not feel discomfort or might experience mild obscure pain. If the movement of the stone stimulates the ureter, it can cause pain in the lower abdomen, often accompanied by the presence of blood in the urine. Diagnosis can be confirmed through color ultrasound or CT scan. For stones in the lower segment of the ureter, treatment depends on the specific size of the stone. If the stone is relatively small, conservative stone expulsion treatment can be done; if the stone is large, surgical intervention is recommended as soon as possible.
