Abstract:

We report a rare case of primary urothelial carcinoma in megaureter in a patient with duplicated collecting system and ureterocele. A 63-year-old male, previously diagnosed with left sided ureterocele and megaureter, presented with gross hematuria. Cystoscopy revealed bleeding from left ureteral orifice. Urine cytology showed poorly differentiated urothelial carcinoma. MSCT urography, with delayed excretory scans, showed duplicated dysplastic kidney with impaired function, with enhancing neoplasm within dilated upper-pole moiety ureter, not outlined on delayed scans. The patient underwent a successful left nephroureterectomy. Pathology revealed high-grade papillary urothelial carcinoma confined to the ureter. There was no evidence of recurrence during two-year follow-up.
