Summary

Two out of three tumours in the upper urinary tract are located in the renal pelvis. Muscle-invasive urothelial carcinoma is probably more common among tumours in the upper urinary tract compared to tumours in the urinary bladder. Thus, muscle-invasive tumours represent approximately 45 % of renal pelvic tumours compared to 25 % of tumours within the urinary bladder. As in the bladder, lymph node metastases are rare in non-muscle invasive disease. Information regarding indications, extent and possible curative potential is currently lacking for lymphadenectomy in conjunction with nephroureterectomy for urothelial carcinoma in the upper urinary tract (UUTUC). There are, however, retrospective series with survival data for patients with lymph node metastasis that report long term survival after surgery as monotherapy \[4\] with similar survival proportions as in bladder cancer with lymph node metastases after radical cystectomy. A retrospective study from Tokyo was expanded to the only available prospective study, where 68 patients with UUTUC were submitted to template-based lymphadenectomy. Another retrospective study by the same Japanese group, showed that 5-year cancer-specific and recurrence-free survival was significantly higher in the complete lymphadenectomy group than in the incomplete lymphadenectomy or without lymphadenectomy groups. Tanaka N et al. reported recurrence rate after nephroureterectomy without lymphadenectomy at 1 and 3 years were 18.9 and 29.8 %, respectively.

Conditions

  • Ureteral Neoplasms

Interventions

PROCEDURE

Lymphadenectomy in conjugation with nephroureterectomy

Lymphadenectomy (intervention group only): Lymphadenectomy performs in four fractions on the right side and two fractions on the left side according to Dissection template (Appendix 1). Renal hilar nodes are included in fraction 1 and 3, respectively.

PROCEDURE

Nephroureterectomy without lymphadenectomy

Removing the kidney, ureter and bladder cuff
