During the 1980s, reports of nephrocolic fistulas, with or without involvement of the skin, were commonly caused by genitourinary tuberculosis. Due to improvements in diagnosis and specifically the development of anti-Koch\u2019s therapy, the incidence of nephrocolic or nephrocolocutaneous fistulas has become uncommon especially in developed countries.<\/jats:p>\n               <jats:p>We report a case of a patient residing in a developing country, presenting with a 20-year\u2009history of a left flank lesion extruding minimal purulent output daily. He was seen at the emergency department due to weakness and was managed as a case of urosepsis. Contrast-enhanced CT scan and fistulogram showed a staghorn calculus in the left kidney with connections to the descending colon and skin. The patient eventually underwent a left hemicolectomy with en bloc excision of the kidney and fistula tract.<\/jats:p>","DOI":"10.1136\/bcr-2022-249351","type":"journal-article","created":{"date-parts":[[2023,1,18]],"date-time":"2023-01-18T11:05:15Z","timestamp":1674039915000},"page":"e249351","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Nephrocolocutaneous fistula from a staghorn calculus"],"prefix":"10.1136","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3715-0315","authenticated-orcid":false,"suffix":"III","given":"Cesar Karunungan","family":"Jacinto","sequence":"first","affiliation":[{"name":"Department of Surgery, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael Geoffrey Lee","family":"Lim","sequence":"additional","affiliation":[{"name":"Department of Surgery, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0887-2498","authenticated-orcid":false,"given":"Marc Paul Jose","family":"Lopez","sequence":"additional","affiliation":[{"name":"Department of Surgery, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dennis Pestano","family":"Serrano","sequence":"additional","affiliation":[{"name":"Department of Surgery, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2023,1,18]]},"reference":[{"key":"2025082722031925000_16.1.e249351.1","doi-asserted-by":"crossref","unstructured":"Borg MA .
