Abstract

|
Upper urinary tract urothelial carcinomas involving renal pelvis or ureter are relatively uncommon, accounting for 5-7% of all renal tumors and about 5% of all urothelial tumors. The most common symptom is gross or microscopic hematuria. Flank pain and lumbar mass are common symptoms of upper tract urothelial carcinoma. Diagnosis of upper urothelial carcinoma based on imaging study included computed tomography urography, cystoscopy with urine cytology, and diagnostic ureteroscopy with biopsy. The traditional pitfalls of upper tract urothelial carcinoma diagnosis, namely poor visualization and difficulty in obtaining representative histological samples, are being circumvented by the introduction of modern digital flexible ureteroscope that can be combined with phothodynamic diagnosis and narrow band image to improve tumor classification, deferring to conservative treatment. The accuracy of the diagnostic work-up of upper tract urothelial carcinoma is very important for decision-making of treatment. The development of technology can allow us more accurate biological information of upper tract urothelial carcinoma.
