    Abstract:
    Primary primitive neuroectodermal tumor (PNET) of the urinary tract is a rare disease with aggressive behavior and poor prognosis. We analyzed 851 cases of urinary tract malignancies in our hospital between 1984 and 2004. Only three (0.035%) cases with PNET of the urinary tract were identified. Presenting symptoms included flank pain and hematuria. The first case was a 44-year-old man with left renal PNET who underwent hand-assisted laparoscopic radical nephrectomy and adjuvant chemotherapy. There was no recurrent tumor at the 4-year follow-up. The second case was a 75-year-old woman with right renal PNET with inferior vena cava (IVC) thrombosis extending to the right atrium. The patient underwent right radical nephroureterectomy and IVC thrombectomy with cardiopulmonary bypass. She died of metastatic disease 7 months later. The third case was a 45-year-old man with left ureteral PNET. Left ureteral segmental resection and partial cystectomy were performed. Tumor recurrence was noted 7 years later. The patient died of disseminated disease 1 year after the discovery of recurrence. Urinary tract PNET appears to be an aggressive malignancy. Long-term survival is possible if complete resection is performed at an early stage.
