A 17-year-old girl with the diagnosis of right renal hydatid disease was treated by retroperitoneoscopic technique. No complications occurred at peroperative and postoperative periods. There were no clinical symptoms and radiologic pathologic causes to show recurrence at postoperative second year. This is the first case that is reported via retroperitoneoscopic laparoscopic approach at the treatment of renal hydatidosis in children. We prefer retroperitoneoscopic approach to avoid intraperitoneal contamination. Retroperitoneoscopic laparoscopic treatment can be an alternative treatment technique at renal hydatidosis therapy because of its advantages to conventional surgery, Although further reports of its long-term outcomes and additional experiences are necessary.
