The mean and median indwelling times (range 0\u2013306 days) of the foreign bodies were 58.3 and 1.5 days, respectively. Computed tomography (CT) scans were conducted in six patients, and the extent and nature of the foreign bodies were well-visualized on CT scans. The removal access was new PCN access (n\u2009=\u20098), the tract missing PCN catheter (n\u2009=\u20093), pre-existing PCN access (n\u2009=\u20092), and percutaneous dissection (n\u2009=\u20091). The removal success rate was 92.9% (13\/14) with either a simple (n\u2009=\u20098) or modified (n\u2009=\u20094; combination of a snare and guide wire is used) snare technique or a direct forceps grasp (n\u2009=\u20091). The mean procedure time for successful cases was 14.2 min (range 7\u201325 min). Procedure-related hematoma with (n\u2009=\u20092) or without (n\u2009=\u20091) renal pelvis injury occurred in three patients, which were all self-limited within one week.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Percutaneous antegrade removal is safe and effective for urinary tract foreign bodies.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/0284185120950127","type":"journal-article","created":{"date-parts":[[2020,8,19]],"date-time":"2020-08-19T00:38:41Z","timestamp":1597797521000},"page":"1097-1103","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Percutaneous antegrade removal of foreign bodies in the urinary tract:  a 20-year, single-center experience"],"prefix":"10.1177","volume":"62","author":[{"given":"Lin","family":"Zheng","sequence":"first","affiliation":[{"name":"Department of Radiology, The Affiliated Cancer Hospital of Zhengzhou University, Zhengzhou, Henan, PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Chul","family":"Cho","sequence":"additional","affiliation":[{"name":"Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2162-419X","authenticated-orcid":false,"given":"Ji Hoon","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Radiology, The Affiliated Cancer Hospital of Zhengzhou University, Zhengzhou, Henan, PR China"},{"name":"Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jung-Hoon","family":"Park","sequence":"additional","affiliation":[{"name":"Biomedical Engineering Research Center, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun Bee","family":"Jang","sequence":"additional","affiliation":[{"name":"Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alrashidi","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Radiology, Prince Sultan Military Medical City, Riyadh, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hai-Liang","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Radiology, The Affiliated Cancer Hospital of Zhengzhou University, Zhengzhou, Henan, PR China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2020,8,18]]},"reference":[{"key":"bibr1-0284185120950127","doi-asserted-by":"publisher","DOI":"10.4293\/JSLS.2014.00271"},{"key":"bibr2-0284185120950127","doi-asserted-by":"publisher","DOI":"10.1007\/s00270-016-1330-5"},{"key":"bibr3-0284185120950127","doi-asserted-by":"publisher","DOI":"10.5152\/tud.2017.67366"},{"key":"bibr4-0284185120950127","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.70.831.9166059"},{"key":"bibr5-0284185120950127","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2008.09.010"},{"key":"bibr6-0284185120950127","doi-asserted-by":"publisher","DOI":"10.1097\/00007611-198910000-00017"},{"key":"bibr7-0284185120950127","doi-asserted-by":"crossref","unstructured":"Kim ET, Yang WJ, Shin JH, et al.
