The symptoms of urethral stones and the size of the stones, as well as their position within the urethra, are directly related. If the urethral stone is relatively small, patients may not experience any discomfort symptoms. By drinking more water and urinating frequently, the stone can be expelled from the body. If the stone is large and causes obstruction in the urethra, it will lead to noticeable symptoms such as urinary obstruction, frequent urination, urgency, and pain during urination. If the stone damages the urethral mucosa, there may also be symptoms of hematuria. If the stone completely blocks the urethra, it will cause urinary retention, and the patient will have significant difficulty urinating. For larger urethral stones, it is necessary to conduct timely ultrasound, CT, and other examinations to determine the specific location of the stone. Appropriate surgical treatments are then selected to crush and expel the stone from the body.
