To report our initial experience of robotic assisted laparoscopic radical cystectomy with extracorporeally reconstructed Y-shaped orthotopic ileal neobladder by using nonabsorbable endo GIA staples From January 2014 to June 2014, We performed robotic assisted laparoscopic radical cystectomy with Y-shaped orthotopic ileal neobladder constructed using nonabsorbable endo GIA staples in total 2 male patients.One patient with urothelial carcinoma clinical stage 2 and the other patient with carcinoma in situ were noted.In our procedure, a 50cm ileal segment is arranged in a Y shape with two segments of approximately 20 cm and two limbs of 5 cm.The jaws of the endoGIA stapler (80 x 3.5 mm) are accommodated within the bowel loop and fired as low as possible, bringing together and detubularizing of each segment of the Y.An opening is made at the lowest point of the Y-ileal segment on its antimesenteric border.The ureters were brought outside the abdominal cavity and freshened and spatulated for approximately 1.5cm.Bilateral double J ureteral stents were then inserted up to the renal pelvis and the ureters were directly anastomosed to the open ends of the limbs of the neobladder.Then performed the anastomosis of The open ends of the U shape and the cutting end of urethra by manual suturing.
