Urethral stones are usually treated by minimally invasive surgery, using holmium laser under urethroscopy or cystoscopy to break up the stones and then remove them from the body. In the case of anterior urethral stones, a lithotripter can be used to remove the stones directly, by injecting paraffin oil and other lubricants into the urethra under adequate anesthesia and using the lithotripter to reach the site where the stones are located. Stones in the posterior urethra are usually pushed into the bladder, where they are broken up within the bladder, and the broken up powder is removed under a cystoscope. However, if the stone in the posterior urethra is too tightly obstructed to be pushed into the bladder, Holmium laser lithotripsy can be performed directly under the urethroscope to break up the stone and then push it into the bladder for powdering. After the procedure, the catheter will be left in place for about 3-5 days, and the stones will be discharged or powdered, and the catheter can be removed for urination.
