RESUMEN
Objective To investigate the clinical application of robot-assisted laparosocopic ureterolithotomy.Methods The clinical data of 28 cases(15 males and 13 females),aged 42(18～72),of laparosocopic ureterolithotomy with AESOP system(computer Motion,USA) was analyzed.Of the 28 cases,18 patients had upper ureter stones and 10 had middle ureter stones.Results All procedures were completely performed by robot assisted laparosocopic ureterolithotomy.The operative time was ranged from 35 to 150 min(averaged 50 min) and the intraoperative blood loss was ranged from 20 to 50 ml(averaged 30ml).The postoperative hospital time was 3 to 5 days and no ureter stricture or recurrent calculus was found during the follow-up period(2～13 months).Conclusion The ZEUS AESOP system has the characteristics of high intelligence and humanization.The robot-assisted laparoscopic ureterolithotomy is effective,safe and precise.
