Mayo Clinic Scottsdale Experience with laparoscopic nephroureterectomy.

OBJECTIVES

To evaluate the efficacy of laparoscopic nephroureterectomy for patients with transitional cell carcinoma of the upper urinary tract.

METHODS

Eighteen patients underwent attempted transperitoneal laparoscopic nephroureterectomy between June 2000 and October 2002. Mean patient age was 67.5 years. The specimen was removed intact through a 7- to 9-cm extraction incision in the lower midline. In the majority of patients, the distal ureter was dissected through the extraction incision.

RESULTS

Sixteen cases were completed laparoscopically. Two cases required conversion to an open procedure. In these cases, dense fibrosis was present around the renal hilum preventing further dissection. The mean operative time was 180 minutes, and the mean estimated blood loss was 160 mL. The mean length of stay was 3.3 days. Complications included the 2 conversions, and 1 patient with a postoperative Mallory Weiss tear. No port-site or distant metastasis occurred; however, 1 patient developed a retroperitoneal recurrence.

CONCLUSION

Laparoscopic nephroureterectomy is an alternative to open nephroureterectomy. Cases with high-stage and grade may cause the laparoscopic dissection to be difficult. The extraction incision allows for easy dissection of the distal ureter.
