Objective: To determine the impact of earlier ureteral ligation (EUL) during hand-assisted retroperitoneoscopic nephroureterectomy (HARN) for primary renal pelvis urothelial cancer.
Methods: We retrospectively reviewed 240 patients with upper urinary tract urothelial cancer who underwent HARN. Only patients with primary renal pelvis urothelial cancer and complete follow-up with a minimum of 1 year after HARN were enrolled into our study. We defined EUL as ligating the ureter prior to pneumoretroperitoneum and mobilizing the kidney during the surgery. Of these 61 patients, 31 (who composed the study group) underwent EUL, while 30 serving as controls were without ureteral ligation during the surgery. We analyzed intravesical recurrence utilizing log rank testing to assess the significance between the two groups.
Results: Clinical parameters were similar between the two groups. The median follow-up after HARN was 39.7 months (range 12-96). There was no significant difference in the rate of intravesical recurrence and cancer-specific survival. However, patients without ligation of the ureter had shorter time to first bladder tumor recurrence (11.7 ± 9.1 months vs. 26.4 ± 19.1 months, p = 0.03).
Conclusion: EUL during HARN for primary renal urothelial cancer did not affect intravesical recurrence rate or cancer-specific survival.
