For the treatment of urethral stones, we first need to use ultrasonography or CT scans to determine the exact location and size of the stones within the urethra for treatment. If the stone is relatively small, such as about five millimeters, this condition can be treated by drinking more water and urinating frequently, relying on the flushing action of the urine to expel the stone from the body promptly. If the stone is larger, and has caused obstruction in the urethra, it is necessary to see the specific location of the stone. If it is causing obstruction in the posterior urethra, a cystoscope can be used to push the stone back into the bladder before performing lithotripsy. If the obstruction is in the anterior urethra, a small amount of liquid paraffin oil can be injected into the urethra to squeeze the stone out, or treatment can be conducted through holmium laser lithotripsy or open surgical stone removal.
