The formation of urethral stones generally does not occur in the urethra itself; most urethral stones form in the bladder or kidneys. During the process of stone elimination, they fall into the urethra, thus forming urethral stones. After urethral stones occur, patients often experience noticeable pain during urination and a sensation of urinary obstruction. Some patients may also exhibit symptoms of hematuria and should promptly visit the hospital's urology department for an ultrasound to determine the exact size and location of the stones. If the stones are small, it is recommended to drink plenty of water and urinate frequently to flush the stones out of the body. If the stones are larger and become lodged in the urethra, it is advised to seek surgical treatment as soon as possible to break down and eliminate the stones.
