RESUMO
Unilateral hydronephrosis can complicate a far from negligible number of patients with Crohn's disease. Bilateral hydronephrosis associated with Crohn's disease is a much more unusual entity. In the other hand, the treatment for this condition is still controversial. We present the case of a 44 year old female with several bowel obstruction episodes caused by ileocolic Crohn's disease. During the last episode she was also diagnosed of bilateral hydroureter and hydronephrosis. After the resolution of the bowel obstruction and the placement of a double J catheter in both ureters, the patient was operated. Ileocolic resection and bilateral ureterolysis with omental wrapping were performed. Although urinary and wound infection complicated the postoperative course, and a enterocutaneous fistula had to be medically treated one year later, the patient is now free of symptoms and her renal function is normal.
