  • Title: Erosive bladder perforation as a complication of ventriculoperitoneal shunt with extrusion from the urethral meatus: case report and literature review.
    Author: Pohlman GD, Wilcox DT, Hankinson TC.
    Journal: Pediatr Neurosurg; 2011; 47(3):223-6. PubMed ID: 22222434.
    Abstract:
    Ventriculoperitoneal (VP) shunt surgery is the most common technique used in the treatment of hydrocephalus. Erosive bladder perforation is an extremely rare complication of VP shunt surgery. Only 2 cases of erosive bladder perforation by a peritoneal catheter have been reported in the English literature. The authors present the case of a 14-year-old male with a history of cerebral palsy, severe developmental delay and hydrocephalus who presented with VP shunt tubing protruding from his urethral meatus. The patient had no evidence of neurological change. The VP shunt had been last revised over 11 years prior to admission. Imaging demonstrated the VP shunt to be intact, but displaced inferiorly, with the ventricular catheter in the extracranial soft tissue of the neck and the peritoneal catheter passing into the abdomen, bladder, and out through the urethra. Shunt removal was achieved through a multidisciplinary approach, involving both neurosurgery and urology teams. The authors discuss other reported cases of perforation by a VP shunt, potential mechanisms, and considerations for management of this rare complication.
