Abstract
The insertion of a ventriculoperitoneal shunt (VPS) is considered the standard of
care for several forms of hydrocephalus. Abdominal complications are most common with
this procedure, comprising up to 30% of all shunt-related problems. Conversely, visceral
perforation or extrusion of the shunt apparatus is rare. Herein we report a rare complication
of VPS insertion in which the peritoneal catheter was spontaneously extruded through
the urethra of a patient with a neobladder. We further discuss the pathogenesis, diagnosis,
and treatment of this condition.
