Abstract
PURPOSE: To propose a state-of-the art of current knowledge about clinical, ureteroscopic and photodynamic for the diagnosis of the upper urinary tract cancer (UTUC). MATERIAL AND METHOD: A systematic review of the literature search was performed from the database Medline (NLM, Pubmed), focused on the following keywords: urothelial carcinomas; upper urinary tract; ureter; renal pelvis; diagnosis; fluorescence; ureteroscopy; photodynamic technique; biopsy; cytology. RESULTS: Gross hematuria and flank pain are the two main clinical symptoms revealing a UTUC in daily clinical practice. Urinary cystoscopy and cystoscopy are mandatory to rule out a concomittant synchronous bladder tumour. Flexible ureteroscopy has revolutionized the management of UTUC by allowing a full exploration of upper urinary tract, an endoscopi vizualization of the tumour and assessment of grade with biopsies. A flexible ureteroscopy is mandatory in diagnostic evaluation of UTUC as soon as a conservative management is being considered. New investigation technologies such as fluorescence, narrow band imaging and optical coherence tomography (± combined with ultra sound), are promising for a near future. CONCLUSION: It has to be understood that the diagnostic work-up of a UTUC has to be exhaustive and particularly the search of another urothelial carcinoma within the urinary tract. Flexible ureterosocopy has revolutionized the diagnosis and management of UTUC and belongs fully to its initial evaluation.
