For urethral stones, if hematuria occurs, the size of the urethral stones should be first considered. Generally, urethral stones are caused by kidney stones or ureter stones that move to and become lodged in the urethra, with the main symptoms being blood in the urine, difficulty urinating, and even urinary retention.

If the urethral stone is relatively small, exercising more and drinking more water usually can help in expelling the stones out of the body; this generally applies to stones smaller than four millimeters. If the stone is larger and cannot be expelled, it is recommended to undergo cystoscopy to push the stone back into the bladder to be broken up and removed, or to directly remove the stone through the urethra. Additionally, if the stone is very close to the external opening of the urethra, it can also be removed using hemostatic forceps to clamp out the urethral stone.
