Retroperitoneoscopic technique for treating symptomatic caliceal diverticula

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