Objective:To present our experience and technique with robot-assisted uretero-neocystos tomy(RAUN)procedure in adults.Methods:Between February 2015 and August 2018,a total of 30(34 ureters)patients who un-derwent RAUN surgery under a single surgeon were retrospectively reviewed.Perioperative data such as age,sex,body mass index(BMI),American society of anesthes iologists score,esti-mated blood loss,surgical technique,operative time,complications,length of hospital stay,and stent removal time were recorded.During the follow-up,patients underwent renal func-tion test,urinalysis,and renal ultrasound examination for evaluation.Success was defined as symptomatic and radiologic relieve.Lastly,a literature search was conducted to review all published articles regarding RAUN surgery in adults.Results:The patients'mean age,BMI,EBL,operative time,and follow-up period were 45.4 years,23.1 kg/m^2,65.6 mL,182.9 min,and 21.3 months,respectively.The two most common indications for the surgery were benign ureteral strictures and ureteric injuries secondaryto a previous radical hysterectomy.Of the 34 cases,26(76.5%)and 8(23.5%)patients received pri-mary RAUN and RAUN with psoas hitch technique,respectively.Refluxing RAUN method was performed in all cases.No intraoperative complications were found.Two patients had a radio-logic and symptomatic recurrence;one was managed with a repeat surgery while the other received ureteral dilatation treatment.Conclusion:Both our study and the published literature showed that RAUN is a safe,less inva-sive,and effective surgical technique that can easily replicate the open ureteroneocystostomy for managing lower ureteral diseases.
