We evaluated 18 patients with renal pelvic and ureteral carcinoma focusing on the operative treatment. All the patients underwent nephroureterectomy and partial cystectomy, except for two patients, with CIS of the ureter and renal insufficiency, and one with invasive bladder carcinoma, in whom partial ureterectomy and total cystectomy were performed, respectively. Lymphadenectomy were performed in all the patients and resected lymph nodes were from renal hilus, para-aorta or vena cava, according to the affected side, intra aorto-caval and all the pelvic nodes in the affected side. Lymph node metastases were found in 4 patients (22%), 2 in the primary and distant nodes and the other in the regional nodes only. Skipped lesion of the lymph node metastasis was not rare and lymph node dissection from the renal hilus to the pelvis on the affected side should be included in the operative treatment of renal and ureteral carcinoma.

We report a case of primary appendiceal cancer that metastasized to the ureter. The patient was a 51-year-old woman who complained of persistent left back pain and right lower abdominal pain. After a detailed examination she was diagnosed to have cancer of the appendix, multiple liver metastases, and left hydronephrosis. Since an obstruction of the ileocecum was obvious, she underwent an ileocecal resection and a resection of the spindle-shaped tumor invading the left ureter. Lymph node metastases were found at the root of the superior mesenteric artery. The spindle-shaped tumor was considered to be due to invasion of the appendiceal cancer to the left ureter. The patient died 5 months postoperatively.

The incidence of transitional cell carcinoma of the kidney and ureter is low and for that reason limited data exists regarding the appropriate management of regional retroperitoneal lymph nodes. Lymph node metastases have consistently been associated with an adverse prognosis. However, five-year cancer-specific survival following nephroureterectomy and lymphadenectomy for patients with lymph node involvement ranges from 0-39%, suggesting a therapeutic benefit. This review covers the primary tumor characteristics associated with lymph node involvement, imaging of the lymph nodes, as well as the rationale, role, patient selection, suggested anatomic templates, and technical considerations for lymphadenectomy.
