A Self-inserted Foreign Body in the Urinary Bladder and Urethra Due to Autoerotism: Two Case Reports

Most foreign bodies in the lower genitourinary tract are self-inserted through the urethra, often due to psychosexual issues, sexual curiosity, or autoerotic behaviour. A variety of foreign objects have been reported, including screws, pens, nuts, electrical or telephone wires, plastic tubes, and writing utensils like pens and pencils. Diagnosis typically involves taking a thorough clinical history, conducting a physical examination, and utilizing imaging studies. Treatment depends on the size, location, shape, and mobility of the foreign body. In most cases, minimally invasive procedures, such as endoscopic removal, are preferred to prevent bladder and urethral injuries. However, in certain cases, more invasive approaches, such as open surgery or suprapubic cystostomy, may be necessary. We present two cases of self-inserted foreign bodies in the urinary bladder and urethra. The foreign body in the urethra was removed via cystoscopy, while the foreign body in the bladder was extracted through an open suprapubic cystostomy.
