The role of ultrasound-guided percutaneous catheter drainage (US-PCD) via the anterior-posterior (AP) approach warrants further evaluation. This case series retrospectively analyzed 10 patients with PA who underwent US-guided AP-PCD at Beijing Friendship Hospital. Data collected included procedure duration, pre- and postoperative clinical examinations, inflammatory markers, and imaging findings. Technical success was achieved in all cases (median procedure time: 18.5 minutes). Postprocedural Visual Analog Scale (VAS) pain scores decreased within 24 hours. By postoperative day 3, eight patients had normalized body temperature and white blood cell (WBC) counts. Median C-reactive protein (CRP) levels decreased from 151.3 mg\/L (range: 58.0\u2013269.4) preoperatively to 49.5 mg\/L (range:38.7\u2013186.1) postoperatively. During a follow-up period of 1\u20136 months, six patients achieved clinical success without further intervention, two required surgical debridement, and two died. This case series demonstrates that US-guided AP-PCD represents a feasible and safe minimally invasive option for selected patients with PA, offering the advantages of real-time guidance and no radiation exposure. However, given the modest success rate (60%) and etiological heterogeneity of this cohort, larger prospective studies are needed to validate its clinical role.<\/jats:p>","DOI":"10.1177\/00368504261448292","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T14:12:41Z","timestamp":1778076761000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasound-guided anteroposterior percutaneous catheter drainage for the treatment of psoas abscess: A case series"],"prefix":"10.1177","volume":"109","author":[{"given":"Jing","family":"Liu","sequence":"first","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-0488-212X","authenticated-orcid":false,"given":"Xianquan","family":"Shi","sequence":"additional","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gai","family":"Li","sequence":"additional","affiliation":[{"name":"North China University of Science and Technology Affiliated Hospital, Tangshan, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lanyan","family":"Qiu","sequence":"additional","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xia","family":"Ma","sequence":"additional","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Yang","sequence":"additional","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yunyun","family":"Dong","sequence":"additional","affiliation":[{"name":"Capital Medical University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,6]]},"reference":[{"key":"e_1_3_7_2_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0041-1735901"},{"key":"e_1_3_7_3_2","doi-asserted-by":"publisher","DOI":"10.1093\/postmj\/qgad110"},{"key":"e_1_3_7_4_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2334-13-578"},{"key":"e_1_3_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajem.2018.05.021"},{"key":"e_1_3_7_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amsu.2021.01.040"},{"key":"e_1_3_7_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/SLE.0000000000000879"},{"key":"e_1_3_7_8_2","doi-asserted-by":"publisher","DOI":"10.1097\/MD.0000000000019640"},{"key":"e_1_3_7_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(03)00274-5"},{"key":"e_1_3_7_10_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41394-022-00488-9"},{"key":"e_1_3_7_11_2","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.2252011443"},{"key":"e_1_3_7_12_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm13113199"},{"key":"e_1_3_7_13_2","doi-asserted-by":"publisher","DOI":"10.4103\/jmas.JMAS_184_20"},{"key":"e_1_3_7_14_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-020-03344-9"},{"key":"e_1_3_7_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/RHU.0000000000001320"},{"key":"e_1_3_7_16_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12082760"},{"key":"e_1_3_7_17_2","doi-asserted-by":"publisher","DOI":"10.1089\/sur.2019.056"},{"key":"e_1_3_7_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjsurg.2007.07.032"},{"key":"e_1_3_7_19_2","doi-asserted-by":"publisher","DOI":"10.3389\/fimmu.2023.1237729"},{"key":"e_1_3_7_20_2","doi-asserted-by":"publisher","DOI":"10.4103\/0019-5413.125506"},{"key":"e_1_3_7_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(97)80036-0"},{"key":"e_1_3_7_22_2","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.54.4284"},{"issue":"1","key":"e_1_3_7_23_2","first-page":"17","article-title":"Presentation, management and outcomes of iliopsoas abscess at a University Teaching Hospital in Nepal","volume":"8","author":"Sah JK","year":"2023","unstructured":"Sah JK, Adhikari S, Sah G, et al.
