Urinary bladder perforation, intra-corporeal knotting, and per-urethral extrusion of ventriculoperitoneal shunt in a single patient: case report and review of literature



Ventriculoperitoneal shunt (VPS) surgery is the most common procedure performed for the treatment of hydrocephalus. Erosive bladder perforation by a peritoneal catheter is an extremely rare complication of VPS. Only ten cases involving the normal (non-augmented) urinary bladder have been reported so far.


We report a case of erosive bladder perforation, intra-corporeal knot formation, and perurethral extrusion of the distal end of VPS. This is the second only case report so far in the world literature showing triad of uncommon VPS complications in a single patient.


Prompt management could avoid further complications. Patient’s parents should be aware about this rare complication, so that they can seek timely medical help.
