title: [Management of urinary complication in Crohn's disease].
abstract: OBJECTIVE
  Although urinary complications of Crohn's disease are relatively rare, they often present diagnostic and therapeutic dilemmas. However, there is no established strategy for treating urinary complications of Crohn's disease. In the present clinical study, we describe the frequency of urinary complications of Crohn's disease, and discuss various approaches to their diagnosis and treatment.
  
  
  METHODS
  The subjects were 1,551 patients who underwent medical treatment for Crohn's disease between January 1994 and May 2002 at Social Insurance Central General Hospital. The subjects were retrospectively evaluated.
  
  
  RESULTS
  Urinary complications occuered in 75 of the 1,551 patients (4.8%): urolitiasis in 60 patients, urinary fistula in 14 patients, and urachal abscess (Enterourachocutaneous fitulas) in 1 patient. A total of 41 of the 75 patients with urinary complications (55%) consulted a practicing urologist: 26 patients with urolithiasis, 14 patients with urinary fistula and 1 patient with urachal abscess. 26 patients with urolithiasis received medical treatment: 20 patients underwent conservative therapy, 4 patients underwent ESWL, and 2 patients underwent TUL. In all 26 of those cases, the treatment was successful. Twelve of the 14 patients with urinary fistulas (86%) underwent resection of the inflamed intestine combined with reconstruction of the urinary tract. The 1 patient with urachal abscess underwent resection of the urachus and the inflamed intestine, and partial cystectomy.
  
  
  CONCLUSIONS
  All patients with urolithiasis should be treated the same way, whether or not they have Crohn's disease. In patients with Crohn's disease complicated by urinary fistula, surgery should be performed after preoperative medical therapy, as it improves the quality of life of such patients more rapidly than other approaches and may help avoid intestinal resection.
