title: [Retroperitoneal fibrosis without dilatation of the upper urinary tract and non-obstructive anuria].
abstract: OBJECTIVE
  An unusual case of retroperitoneal fibrosis with non-obstructive anuria is described and the therapeutic alternatives are discussed. METHODS/ RESULTS: Repeated obstruction of the double-J ureteral catheter and intense lumbar pain did not permit endourological management and surgery was required. Excellent results were achieved and the patient is asymptomatic 12 months postoperatively.
  
  
  CONCLUSIONS
  Conservative endourological management and corticosteroids may not always be feasible. The anuria without dilation in the case described is not unlike other reported cases considered as reflex anuria whose mechanism remains unknown.
