title: Simultaneous bilateral renal pelvic tumors.
abstract: BACKGROUND
  A 72-year-old man was admitted with gross hematuria. Investigations revealed bilateral renal pelvic tumors.
  
  
  RESULTS
  Via a midline incision, left nephroureterectomy with bladder cuff resection was performed for the large left-sided tumor. The right small solitary right-sided tumor was endoscopically resected simultaneously. Histologically, both tumors were grade 2 transitional cell carcinomas without muscular invasion.
  
  
  CONCLUSIONS
  There has been no evidence of recurrence or metastasis 30 months postoperatively.
