How does the urethra have stones?

Urethral calculi may be related to factors such as concentrated urine, urinary tract infection, urinary tract foreign bodies, etc.

1. Concentrated urine When a

large amount of water is lost in the body, after a long time without urination or drinking too little, the components in the urine will crystallize out and form calculi.

2. Urinary tract infection

After urinary tract infection, bacteria can decompose urea in the urine into ammonia, and urine becomes alkaline, which is conducive to the deposition of phosphate and carbonate, and gradually can form calculi.

3. Urinary foreign bodies

There are surgical residues or sutures in the urethra, and long-term indwelling catheters, etc., which may cause iatrogenic urinary calculi.
