title: [Rupture of kidney pelvis in retroperitoneal fibrosis].
abstract: OBJECTIVE
  To present a case of rupture of the renal pelvis in a patient with idiopathic retroperitoneal fibrosis and no previous dilatation of the left excretory system.
  
  
  RESULTS
  A patient with retroperitoneal fibrosis underwent surgery for ureterolysis and intraperitonealization of the right ureter. The control IVP was unremarkable. One week later, however, rupture of the left renal pelvis was observed, which was resolved by placement of a ureteral catheter.
  
  
  CONCLUSIONS
  In the case described, rupture of the renal pelvis without previous obstruction could be due to ureteral akinesia associated with the retroperitoneal fibrosis.
