Pouch urinary tract fistulae are rare. We aimed to describe the presentation, diagnostic workup, and management of patients with pouch urinary at our center.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Our prospectively maintained pouch registry was queried using diagnostic codes and natural language processing free-text searches to identify ileoanal pouch patients diagnosed with any pouch-urinary tract fistula from 1997 to 2022.

Overall median age was 42 (27\u201362) years, and 92.3% of the patients were male. Fistula locations included pouch-urethra in 13 patients (48.1%), pouch-bladder in 12 patients (44.4%), and anal-urethra in 2 (7.4%). The median time from pouch to fistula was 7.0 (0.3\u201338) years. Pouch excision and end ileostomy were performed in 12 patients (bladder fistula, <jats:italic>n<\/jats:italic>\u2009=\u20093; urethral fistula, <jats:italic>n<\/jats:italic>\u2009=\u20099), while redo ileal pouch-anal anastomosis (IPAA) was performed in 5 patients (bladder fistula, <jats:italic>n<\/jats:italic>\u2009=\u20093; urethral fistula, <jats:italic>n<\/jats:italic>\u2009=\u20092). The 5-year overall pouch survival after fistula to the bladder was 58.3% vs. 33.3% with urethral fistulae (<jats:italic>p<\/jats:italic>\u2009=\u20090.25).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Pouch-urinary tract fistulae are a rare, morbid, and difficult to treat complication of ileoanal pouch that requires a multidisciplinary, often staged, surgical approach.
