Spider-man, magnets, and urethral-cutaneous fistula.

Self-inserted foreign bodies in the genitourinary tract or externally attached to the male genitalia can be challenging to the urologist. These cases often necessitate urgent assessment and intervention. We present the case of a 12-year-old boy who inserted 1 magnet into his urethra and placed a second on the ventral surface of the penis. This led to the development of a urethral-cutaneous fistula. To our knowledge, this is the first reported case illustrating the development of an iatrogenic fistula after self-insertion of a foreign body in the genitourinary tract. Copyright 2010 Elsevier Inc.
