title: [Tumor grafts in the upper urinary tract secondary to tumors of the bladder epithelium].
abstract: A retrospective study of cases seen between 1975 and 1985 showed 24 tumors of upper urinary tract secondary to primary bladder localizations. These secondary localizations developed during evolution of multi-resected recurring bladder tumors, within a mean period of 15 months after discovery of a secondary vesicorenal reflux. This reflux is acquired constantly during the course of these tumors and it is undoubtedly responsible for the onset of these upper tract tumoral grafts. These findings suggest the need for urographic surveillance combined with regular endoscopic examinations of patients with bladder tumors, for prevention of reflux during endoscopic resections and for treatment of any reflux detected.
