Retroperitoneoscopic Treatment of Caliceal Diverticular Calculi: Report of Two Cases and Review of the Literature

Abstract

Two women with symptomatic stone-filled caliceal diverticula were treated by a retroperitoneoscopic approach. With a three-port technique, the diverticulum was marsupialized, the calculi removed, the cavity fulgurated, and perirenal fat inserted. The patients had no morbidity and remain stone and symptom free. They represent the 17th and 18th reported cases of this condition. We also review the clinical results in the literature.

Management of stones in calyceal diverticulum

“…Initially, retroperitoneoscopy was performed using four or five ports, but recent cases have been managed successfully using a three-port approach [19]. Important adjuncts to the retroperitoneoscopic approach include retrograde ureteral access, intraoperative laparoscopic ultrasound, and laparoscopic freehand suturing [35]. Accessibility of energy sources such as lasers, argon beam, or electrocautery is crucial.…”
