Percutaneously inserted ventriculo-ureteral shunt as a salvage treatment in paediatric hydrocephalus: a technical note

Background Hydrocephalus is a challenge for paediatric neurosurgeons. When the abdominal cavity and heart fail as diversion sites for cerebrospinal fluid (CSF), many of the otherwise used alternative diversion sites are not feasible due to the smaller physical body size of children and infants. Using the urinary system as a site of diversion has been described in adults primarily. Objective To describe a minimally invasive procedure to percutaneously access the ureter for placement of a distal catheter in the treatment of paediatric hydrocephalus. Methods A percutaneous ultrasound-assisted technique was used to access the renal pelvis for catheter placement into the distal ureter. Results Fifteen months after the surgery, the child has a stable neurological condition and adequately managed hydrocephalus. Conclusion The urinary tract should be considered a viable option for CSF diversion in complex paediatric hydrocephalus. A multidisciplinary approach consisting of interventional radiologists, urologists and neurosurgeons should be involved in the evaluation of potential candidates.
