We report our experience with closure of the bladder during laparoscopic nephroureterectomy by using a gastrointestinal anastomosis type stapling device designed to deliver 6, 3 cm. rows of 3.5 mm. titanium staples via a 12 mm. trocar. We initially used this stapling device to secure a cuff of bladder in 8 female pigs undergoing laparoscopic nephroureterectomy. Followup in these animals was completed 2 to 6 months postoperatively. Then, 3 patients underwent laparoscopic ureterectomy using the laparoscopic stapler to transect and secure the ureter along with a cuff of bladder. In neither the laboratory nor the clinical situation were any complications encountered due to the transvesical staples (for example extravasation, stone formation, urinary tract infection or abscess formation). Our preliminary results indicate that titanium staples may be an effective method to provide rapid and secure closure of the bladder in patients undergoing either laparoscopic nephroureterectomy or laparoscopic ureterectomy.
