Abstract
Purpose We review the morbidity and long-term outcome of percutaneous caliceal diverticulectomy and associated stone extraction. Materials and Methods Percutaneous caliceal diverticulectomy was performed in 19 women and 11 men (age range 20 to 58 years), of whom 26 had stones (all 15 mm. or less). The diverticula were located throughout the kidney, including the upper (11 patients), middle (15) and lower (4) calices. Percutaneous caliceal diverticulectomy included 28 direct and 2 indirect accesses (1 via a previously placed nephrostomy tract and 1 due to stones in other areas of the kidney). In all cases the stone was removed and the diverticular neck was incised or dilated. Fulguration of the diverticular walls was performed in 22 cases. Transdiverticular percutaneous renal and ureteral drainage was maintained from 2 to 7 days until a nephrostogram demonstrated no extravasation. Results The average operating room time and hospital stay were 171 minutes (range 75 to 330) and 4.1 days (range 2 to 7), respectively. Major complications occurred in 6.6% of the cases, requiring 1 blood transfusion and 1 chest tube placement, and minor complications occurred in 13.4%. There was no mortality. Followup for more than 1 year was available in 27 patients. Stone-free rate was 93% with obliteration of the diverticulum in 76% of patients. Overall, 85% of patients are asymptomatic at average followup of 3.5 years (range 1 to 7.3). Conclusions Direct percutaneous endosurgical management provides a safe, efficacious and durable means of treating stone bearing caliceal diverticula, regardless of stone size or location of the diverticulum.
