ABSTRACT
Urothelial tumors of the upper urinary tract are rare, serious diseases that are increasing in frequency. Because of similar embryologic and histologic, pathologic appearance, symptomatology of these tumors are considered as a single entity. We experienced 15 patients with urothelial tumors of the upper urinary tract, who were admitted to our Dept. of Urology during 8 years period from Jan. 1978 to Jan, 1986. The most common symptom was gross hematuria. The most common finding on excretory urogram was a non-visualization of the kidney. Treatment included nephroureterctomy with excision of bladder cuff, nephrectomy and partial ureterectomy, nephroureterectomy and total cystectomy with ileal conduit or Kock continent ileal reservoir. We report 15 cases of urothelial tumors with some review of literatures.
