The video shows a case of a staghorn stone of the right kidney in a female patient 48 years old.The patient complained of recurrent infections and flank pain.The stone occupied entirely the pelvis and most of  the calyces.There was no evidence of ureteropelvic junction obstruction. Two minor calculi were in the mid calyces.
The stone was approched by robotic procedure. The renal pelvis was prepared and opened with V incision. Marked edema and hyperemia were present. The stone filling the entire pelvis and the calyces was dislocated and removed. During  maneuver part of stone in the upper calyx ruptured and was removed apart.The operative time was about 120 minutes . The two residual minor calculi were approched in a second time by endourological procedure.
There was no post operative complication.The patient was discharged after two days.Double J was removed at the third month after endoscopic laser lithotripsy of  two minor calculi. TC control after three months  demonstrated the  absence  of residual stone  and a normal configuration of the urinary tract.
In selected cases of large renal staghorn calculi the robotic surgery is very effective. The specific articulation and the finest movements of the robotic arms allow a complete removal of stone and a precise reconstruction of the urinary tract.
