Patients with urethral stones generally exhibit obvious symptoms such as frequent urination, urgency, painful urination, hematuria, and even urinary retention. These symptoms represent a urological emergency that requires immediate attention. In such cases, it is best to fast and not eat any food. The patient needs to visit the hospital's urology department for ultrasound, CT scans, and other tests to determine the exact size and location of the urethral stones. If the stones are small, drinking more water and urinating frequently can help to expel the stones from the body. If the stones in the urethra are large and cause urinary retention, it is necessary to promptly perform surgery to break up and remove the stones. There are no specific dietary requirements in this regard.
