Urethral foreign body in an adolescent boy: report of two rare cases and review of literature.

The presence of a foreign body in the urethra is uncommon. A wide variety of foreign bodies have been described in urethras, but they are often missed in physical examinations as the patient tries to hide the fact. We report two unusual cases of foreign bodies in the urethra in two adolescent boys suffering from psychiatric disorders. In the first case, a 12-year-old boy presented with introduction of sewing needle into the urethra 3 days back. The patient in that case suffered from a delusional disorder. In the second case, a 19 year old man introduced a metallic screw into his urethra for sexual gratification several times in the preceding 4 years. That patient suffered from schizophrenia. Although psychiatric illness is associated with urethral foreign body, such underlying psychiatric disorders are very rare.
