Hydrocephalus is a complex pathology that can have a significant impact on the quality of life in all age groups. Cerebrospinal fluid (CSF) diversions from the lateral ventricle to the peritoneal cavity are regarded as the treatment of first intent, but they have a high revision rate, and there are multiple factors which can impair their proper insertion and function. One of the many alternatives to peritoneal shunting is redirecting the CSF towards the renal system. A literature search was conducted to identify the particularities of these types of shunts and what clinical context rendered them feasible in pediatric and adult patient populations. Twenty-eight studies were found to meet the selection criteria. The shunts were classified into ventriculopyeloureteral, ventriculoureteral, and ventriculovesical. Their main advantage was that they did not depend on absorption properties of the tissues, like in the case of the peritoneum. However, several issues with ascending infections, bladder pressure imbalance, distal shunt migration, and calculus formation were noted. Literature suggests that the urinary tract can have the potential of diverting CSF when the peritoneum or atrium is not available, but further research is required to establish their proper role in current practice.
