Among the 127 patients who underwent surgical treatment for Crohn's disease at Tohoku University Hospital, urinary complications were noted in 13 patients (10.2%), including urolithiasis in 6 patients (4.7%), a ureteral obstruction in 4 (3.1%), and urinary fistula in 3 (2.4%). In patients with urolithiasis, conservative therapy was effective. An ureteral obstruction was detected on the right side in all 4 of these cases because of the inflamed terminal ileum. In 2 of the 4 cases, the symptoms improved by either preoperative total parenteral nutrition or elemental diet therapy. A resection of the inflamed intestine was necessary in all cases. In patients with urinary fistulas, a resection of the inflamed intestine combined with a reconstruction of the urinary tract was carried out after total parenteral nutrition. In conclusion, conservative therapy with preoperative total parenteral nutrition or elemental diet therapy proved to be effective for a ureteral obstruction since it improved the intestinal inflammation. As a definitive treatment, surgery is still necessary for the management of urinary fistulas and ureteral obstruction. Based on our findings, patients with urolithiasis in Crohn's disease should thus be treated conservatively in the same way as patients without Crohn's disease.
