Robot-assisted Management of Anterior Calyceal Diverticular Calculi

Abstract

Calyceal diverticula are rare outpouchings of the upper collecting system that likely have a congenital origin. The incidence of the stone formation in the calyceal diverticula is up to 50%. The most effective diagnostic method is the computed tomography urogram. Treatment options for symptomatic patients include shock -wave lithotripsy, ureteroscopic or percutaneous methods, and laparoscopic surgery. The treatment option should be selected based on the basis of the diverticulum location and stone burden. This paper reports an interesting case of a 19-year-old boy with a stone burden of 1.663 mm3 in the calyceal diverticula of the right kidney. The patient underwent a robot-assisted procedure using the daVinci© Xi system.
