Foreign body urination

Urinary foreign body sensation is due to foreign body sensation in patients with urinary calculi. Urethral stones are rare in the clinic. Most come from the urinary system of the bladder and above, such as kidney stones, ureteral stones or bladder stones. Stones can stay in the urethra or be embedded in the urethra, scaphoid fossa, or outer urethra of the prostate when discharged. A few are secondary to urethral stricture, urethral atresia, foreign body, or urethral diverticulum. Stones that originate in the urethra are quite rare. It is usually a single stone. The components of the combined infection stones were mostly magnesium ammonium phosphate. Most female urethral stones occur in the urethral diverticulum.
