Basic Reliable Intraperitoneal Extravesical Flexible (BRIEF) Technique in Robotic-Assisted Radical Nephroureterectomy With Excision of Bladder Cuff for Upper Tract Urothelial Carcinoma: Step by Step

ObjectiveTo describe a technique of robotic-assisted radical nephroureterectomy with excision of bladder cuff.MethodIn our institution, a total of 64 patients were enrolled in which 29 patients underwent robotic technique and 35 patients underwent laparoscopic technique. We compared perioperative data and tumor recurrence rates in two groups to confirm the advantages of robotic technique.ResultAll 64 patients finished their operation without converting operation. As the general conditions were no differences, the robotic group had less intraoperative blood loss (36.38±15.86ml verse 50.57±27.94ml, P<0.05), earlier ambulation (7.24±1.37h verse 9.14±2.03h, P<0.05), and shorter hospitalization time (3.55±0.69days verse 6.32±1.68days, P<0.05). And the visual analogue scale scores of the robotic group in 1h, 12h and 24h was lower than traditional laparoscopic group (P<0.05). And tumor recurrence and positive surgical margin were not difference between two groups (P>0.05).ConclusionCompared with laparoscopic method, the robotic technique has the advantages in postoperative recovery.
