After suffering from urethral stones, whether hospitalization is necessary depends first on examinations such as color Doppler ultrasound and CT scans to determine the exact location and size of the stones within the urethra. If the stones are relatively small, such as about five millimeters, hospitalization is not necessary. By drinking more water and urinating frequently, the flushing action of the urine can expel the stones from the body. However, if the stones are larger and become lodged in the urethra, causing significant hematuria or even urinary retention, it is advisable to hospitalize immediately and proceed with surgery. Using a ureteroscope with holmium laser lithotripsy, the stones can be shattered and expelled from the body.
