Rare case of migration and perforation of the urinary bladder by ventriculoperitoneal shunt catheter with intravesical knotted formation: A case report and literature review.

Background: The most commonly used technique in the management of hydrocephalus is a neurosurgical procedure, known as ventriculoperitoneal shunt (VPS). Several complications of the distal end of a VPS catheter have been described in the literature, although migration and erosive bladder perforation of this shunt are extremely uncommon.

Case Description: We relate a rare pediatric case of a 4-year-old boy, with long-term dysuria, intermittent incontinence, and chronic abdominal pain developed during a myelomeningocele postoperative period, without other symptoms.
