to out either side of 6 o’clock, and the suturing is completed circumferentially over a 22 Fr catheter, out to in on the ileal side, and in to out on the urethral
side.

Isolation of neobladder bowel segment and re-anastomosis of the bowel [Figure 4]: once the UIA is complete, as described above, the bowel is divided with
Endo-GIA™ Laparoscopic staplers which are passed through the “fourth arm” 15 mm port, once the robotic instrument has been removed. It is done 10 cm

above the UIA for the right ileal neobladder limb and 40 cm above the UIA for the left ileal neobladder limb. The ileum is then re-anastomosed using both a
60 mm and a 45 mm cartridge, finally closing the upper aspect of the anastomosed bowel with another 60 mm cartridge.

Detubularization of the ileal neobladder limbs and formation of the posterior plate [Figures 5 and 6]: both limbs of the neobladder are opened over the suction
instrument, except for 10 cm of the proximal aspect of the left ileal limb, which forms the “chimney”. Once detubularized, stay sutures are placed to bring the

medial sides of the top of the right ileal neobladder limb to the medial aspect of the left ileal neobladder limb, just at the bottom of the chimney. Two more stay
sutures are placed. First, 10 cm below the chimney, the medial aspect of the left ileal neobladder limb is sutured to the upper aspect of the ileum just above the
UIA. It leaves an open U-shaped loop of 20 cm of the left ileal neobladder limb on the left side of the pelvis. The final stay suture is placed at its most lateral

aspect, bringing the inner aspect of the upper and lower parts of this loop together. With the stay sutures in place, the different parts of the posterior plate are
