Goal: To understand endoscopic third ventriculostomy (ETV) surgical result in the hydrocephalus. Setting: Benha University Hospitals Department of Neurosurgery. Between January 2016 to February 2020. Materials and processes: A total of 58 hydrocephalus patients were included in this research, regardless of gender prejudice. CSF loculation or tumour hydrocephalus was excluded. Hydrocephalus CT scan brain and MRI were diagnosed. Information on patient specifics, causes of hydrocephalus and operation problems were recorded in Performa patient. The data were examined in version 26 of SPSS. Frequency and percentage for categorical variables were computed. Mean ± SD for age has been computed. Results were presented as tables. Results: The research comprised a total of 58 individuals with hydrocephalus. Of the 58 patients, 32 were male (55.2 per cent) and 26 were female (44.8 percent ). The average age was 22.86 months. The most frequent cause of hydrocephalus was congenital aqueductal stenosis. CSF leaking was observed in 20 individuals after surgery (34.5 percent ). 6 individuals have postoperative infection (10.3 percent ). Conclusions: third ventriculostomy endoscopic is safe and effective. Patients who fulfil the requirements are offered the option of freeing themselves from shunt dependence via endoscopic third ventriculostomy.
