Abstract

(Purpose) The usefulness of laparoscopy-assisted total nephroureterectomy for patients with renal pelvic and lower ureteral cancer is evaluated.
(Material) Seven patients with renal pelvic cancer and four with lower ureteral cancer performed laparoscopy-assisted total nephroureterectomy from May 1997 to December 2000 (Ten males and one female, mean age 68.5 year-old).
(Method) Of the 11 patients, the initial one received preoperative embolization of the renal artery. Under general anesthesia laparoscopy-assisted total nephroureterectomy underwent via transperitoneal approach in three patients and retroperitoneal approach in eight. After the kidney was completely dissected under laparoscopic procedure, it was delivered en bloc with ureter from the skin incision in the lower abdomen.
(Result) Two patients needed conversion to open surgery. The mean operating time of nine patients except for conversion cases was 272 minutes and the mean blood loss was 313ml. There was no major complication associated with laparoscopic procedure. There was no significant difference in both complication and recurrence rate between laparoscopy-assisted total nephroureterectomy and open surgery.
(Conclusion) Laparoscopy-assisted total nephroureterectomy is an useful procedure for the treatment of patients with renal pelvic and lower ureteral cancer because it enables us to remove out the kidney and ureter from one small lower abdominal incision.
