FERNANDEZ GONZALEZ, Inmaculada et al. Ureteroscopia diagnóstica anterógrada del tracto urinario superior en la neovejiga ortotópica. Arch. Esp. Urol. [online]. 2005, vol.58, n.2, pp.139-144. ISSN 0004-0614.

OBJECTIVES: To demonstrate the usefulness of antegrade endoscopical examination in the evaluation of the upper urinary tract pathology in patients with orthotopic neobladder. METHODS/RESULTS: We present the technique of percutaneous antegrade ureteroscopy and the indications for treatment of the upper urinary tract urothelial tumor (radical or conservative) depending on multiple pyelo-calyceal biopsies and tumor lesions. CONCLUSIONS: Endoscopical evaluation of the upper urinary tract in patients with orthotopic neobladder offers safer information than urine analysis, urine cytology, and the various radiological tests. The difficulty for retrograde examination is on the identification of the ureteral neomeatus, so that in case of failure, antegrade percutaneous approach allows complete ureteral and pyelocalyceal examination and biopsies thanks to the development of flexible endoscopes. The information supplied by these endoscopical examinations of upper urinary tract urothelial tumors (grade, stage, multifocality) allows the choice of radical or conservative (open surgery or endoscopical) treatment.
