Abstract:
Calculous disease in a caliceal diverticulum is a rare entity. The standard treatment currently is endoscopic surgery with marsupialization or fulguration or both with dilatation of the neck of the diverticulum. We present the fifth reported case of retroperitoneoscopic management of a caliceal diverticulum in a patient with a long history of flank pain and suggest that this treatment offers a stone-free rate comparable to that of open surgery with less morbidity than is associated with endoscopic treatments.
