Robot-Assisted Laparoscopic Management of Caliceal Diverticular Calculi.

Standard treatment modalities of caliceal diverticular calculi range from extracorporal shockwave lithotripsy (SWL) over retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PNL) and laparoscopic stone removal. A 55-year-old woman presented with a history of pyelonephritis based on a caliceal diverticular calculus. Due to the narrow infundibulum and anterior location, a robot-assisted laparoscopic calicotomy with extraction of the calculi and fulguration of the diverticulum was performed, with no specific perioperative problems and good stone-free results. This article shows technical feasibility with minimal morbidity of robot-assisted laparoscopic stone removal and obliteration of a caliceal diverticulum.
