FIGURE 1.

Scenes of the non‐guided full bladder‐neck sparing bladder neck dissection (ngBND) task. A, Showing the bladder neck completely freed. The icon “CLEAR BLOOD” provides a virtual sucker. Opening and closing the right‐handed instrument 1 or left‐handed instrument 2 on the icon activates a functional icon. B, Showing the ventral part of the urethra opened by the curved scissors close to the prostate for maximum bladder neck preservation. The yellow transurethral catheter becomes visible. C, Showing the ventral and dorsal parts of the bladder neck opened in a proceeded phase of the ngBND module. The third robotic instrument arm (fourth arm) is pulling up the transurethral catheter towards the symphysis. The virtual icons “IN” and “OUT” can pull the free catheter in or out
