Presentation was preceded by a 6-month history of alternating faecaluria and increased colostomy output. Laboratory studies were notable for normal anion gap metabolic acidosis. Creatinine level of the colostomy output was 17.7 mg\/dL, a finding indicative of the presence of urine in the sample. CT enterography and X-ray loopogram confirmed neobladder to small intestine fistula.<\/jats:p>\n               <jats:p>Neobladder creation is commonly performed in patients with bladder cancer requiring resection. Fistulas between the neobladder and intestine are observed in fewer than 2.7% of cases. The patient\u2019s history of extensive abdominopelvic resection, colostomy creation and radiation likely contributed to fistula development. We highlight the need for a high index of suspicion for a fistula in a patient with a neobladder experiencing recurrent urinary tract infections or a high colostomy output concurrently with low neobladder output.<\/jats:p>","DOI":"10.1136\/bcr-2022-254170","type":"journal-article","created":{"date-parts":[[2023,12,6]],"date-time":"2023-12-06T12:50:56Z","timestamp":1701867056000},"page":"e254170","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Ileal
