Three women with symptomatic stone-containing caliceal diverticula in the right kidney were treated by extraperitoneal laparoscopic diverticulectomy. The diverticula measured 31 x 21 mm, 15 x 12 mm, and 12 x 9 mm, with the calculi measuring 10 x 8 mm, 5 x 4 mm, and 6 x 6 mm, respectively. The site of the diverticulum was identified by the presence of a depression on the surface of the kidney. The diverticulum was marsupialized, the lining fulgurated, and in the second and third patients, a flap of Gerota's fascia and perirenal fat inserted. The mean operating time was 127 minutes. The mean postoperative analgesic requirement was six doses of pethidine (meperidine). The median time to drainage tube removal was 3 days, and the median time to discharge after surgery was 4 days. Complications were minimal. On follow-up, all patients were stone free and asymptomatic. The first patient had a slight recurrence of the diverticulum, measuring 15 x 7 mm. Laparoscopic caliceal diverticulectomy has been successful in three patients.
