Abstract

OBJECTIVES:

To evaluate the efficacy of retroperitoneoscopic nephroureterectomy for transitional cell carcinoma of the renal pelvis and ureter, we analyzed the clinical outcomes and long-term cancer control of 89 patients.

METHODS:

In 36 patients, the kidney was retroperitoneoscopically dissected and the ureteral end was resected with open procedure (combined laparoscopy group). In 53 patients, the ureteral end with a bladder cuff was transected using an endoscopic stapler (pure laparoscopy group). Sixty patients underwent open nephroureterectomy (open group). The median follow-up period was 35, 31, and 17 months in the open, combined, and pure laparoscopy groups, respectively.

RESULTS:

The average operative time and bleeding volume was 5.4 hours and 665 mL in the open group, 5.1 hours and 580 mL in the combined laparoscopy group, and 4.3 hours and 354 mL in the pure laparoscopy group, respectively. The cause-specific patient survival rate at 3 years was 81% in the open group, 86% in the combined laparoscopy group, and 80% in the pure laparoscopy group. The bladder recurrence-free rate at 3 years was 51% in the open group, 65% in the combined laparoscopy group, and 45% in the pure laparoscopy group. The extravesical recurrence-free rate at 3 years was 71% in the open surgery group, 76% in the combined laparoscopy group, and 71% in the pure laparoscopy group. No statistically significant difference was seen in patient survival, bladder recurrence, or extravesical recurrence rates among the three groups.

CONCLUSIONS:

Our retroperitoneal laparoscopic nephroureterectomy is less invasive than open surgery and is a safe and effective alternative.
