Stones falling down and blocking the urethra are called urethral calculi, which need to be combined with the size and location of the stones to choose between stone removal or surgical treatment.
1. Anterior urethral calculi: if the stone is not large enough to stay in the anterior urethra, the urethra can be enlarged or incised, and the stone can be extracted by clamping, hooking or squeezing, and lubricant should be injected before stone extraction to facilitate stone extraction. If the stone is large and can not be moved by the efforts, urethrotomy can be used to remove the stone.
2. Posterior urethral calculi advocate the use of a probe rod to push the stone back to the bladder, and then according to the bladder stone treatment, but also in the direct vision urethroscopy stone extraction or lithotripsy. Those with urethral stricture or diverticulum complicating the stone should be treated at the same time as stone extraction.
If there are urethral stones, it is recommended that the patient go to a regular medical institution for consultation and standardized treatment under the guidance of a doctor.
