Urethral stones can cause symptoms such as frequent urination, urgency, pain during urination, and hematuria. In severe cases, they can completely block the urethra, leading to urinary retention. If the stones are relatively small, this condition can often be resolved by drinking plenty of fluids and urinating frequently, relying on the flushing action of the urine to expel the stones from the body. However, if the stones are larger and cause urinary retention, it is necessary to promptly use a cystoscope or ureteroscope to visually crush the stones with a holmium laser and expel them from the body. After the procedure, a urinary catheter is left in place, and recovery typically takes about a week. It is important to drink plenty of water and urinate frequently to prevent the formation of stones.
