Objective: To analize our experience in the endoscopical treatment of pediatrichydrocephalus. Methods: In a retrospective study we analyzed 360 hidrocephalic patients treated endoscopically in 5 Pediatric Neurosurgical Services in Buenos Aires. 374 procedures were performed: 207 third-ventriculostomies, 70 septal fenestrations, 48 catheter implantations, 26 cyst-ventriculostomies, 11 septomies, 7 catheter removals, 4 aqueductoplasties and 1 monoplasty. Results: Third ventriculostomy was the most frequent procedure with a very low failure rate (19,8 por ciento). The overall complication rate was 4,5 por ciento. IN pineal tumor related hydrocephalus, a simultaneous biopsy procedure was always sucessful. Conclusions: Endoscopic treatment of hydrocephalus must always be consideraded as an effective method and as the first choice treatment in an important number of patients
