title: Results of double-contrast cystography in cats with idiopathic cystitis: 45 cases (1993-1995).
abstract: OBJECTIVE
  To determine results of double-contrast cystography in cats with idiopathic cystitis.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  45 cats with clinical signs of nonobstructive lower urinary tract disease for which an underlying cause could not be determined.
  
  
  METHODS
  Medical records and double-contrast cystograms performed initially and during 6- and 12-month reevaluations were reviewed.
  
  
  RESULTS
  105 cystograms were reviewed. Fifteen (33%) cats had abnormalities evident on cystograms obtained at the time of initial examination. Of these, only 1 had abnormalities 6 and 12 months later. Thirty cats did not have abnormalities evident on cystograms obtained at the time of initial examination. Of these, 1 had abnormalities on a cystogram performed 6 months later and another had abnormalities on a cystogram performed 12 months later. Abnormalities evident on cystograms included focal thickening of the bladder wall (n = 11), diffuse thickening of the bladder wall (6), irregularities of the bladder mucosa (10), decreased opacity of the bladder wall (3), increased opacity of the bladder mucosa (3), filling defects (4), contrast medium in unexpected locations (3), and altered ureteral opacity (15).
  
  
  CONCLUSIONS
  Results suggested that a large percentage of cats with idiopathic cystitis do not have cystographic abnormalities when initially examined but that abnormalities may be apparent during follow-up evaluations. In addition, a smaller percentage of cats with idiopathic cystitis may have nonspecific cystographic signs of cystitis or hemorrhage. Leakage of contrast medium into the peritoneal space during cystography does not necessarily require surgical management.
