In the macroscopic analysis, the spatial relationships between the perirenal fat (PeRF), pararenal fat, posterior renal fascia (PRF), and extraperitoneal fascia (EPF) were examined. Histological observations focused on the distribution and continuity of adipose compartments and the organization of the surrounding dense fibrous connective tissue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Macroscopically, the EPF covered the anteromedial pararenal fat and extended posteriorly to the kidney. Upon incision, a small amount of adipose tissue was observed directly beneath it. Removing this TAC exposes the peritoneum and PRF with a clear demarcation between them. Histological analysis confirmed that the posterior renal and EPF were distinct, with dense connective tissue structures enclosing a separate TAC. This compartment extended anteriorly between the PeRF and peritoneum, and laterally between the peritoneum and EPF. These extensions converge near the peritoneal reflection in the lateral renal region, forming a characteristic triradiate configuration of adipose tissue.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Our findings challenge the classical notion that the renal fascia is a single continuous layer, supporting a compartment\u2010centered anatomical model. The posterior and lateral regions of the kidney contain a distinct third adipose compartment, bordered by the posterior renal and extraperitoneal fasciae. This model offers improved anatomical clarity and may aid understanding during laparoscopic, retroperitoneoscopic, and robot\u2010assisted surgeries.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/iju.70303","type":"journal-article","created":{"date-parts":[[2025,11,28]],"date-time":"2025-11-28T06:08:29Z","timestamp":1764310109000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Anatomy of Adipose Compartments and Fascial Structures in the Posterolateral Region of the Kidney With Special Focus on the Thin Adipose Compartment"],"prefix":"10.1111","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4981-8818","authenticated-orcid":false,"given":"Atsuhiko","family":"Ochi","sequence":"first","affiliation":[{"name":"Department of Urology Kameda Medical Center  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4709-6359","authenticated-orcid":false,"given":"Satoru","family":"Muro","sequence":"additional","affiliation":[{"name":"Department of Clinical Anatomy Institute of Science, Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sho","family":"Mitsumaru","sequence":"additional","affiliation":[{"name":"Department of Clinical Anatomy Institute of Science, Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3054-0273","authenticated-orcid":false,"given":"Akimoto","family":"Nimura","sequence":"additional","affiliation":[{"name":"Department of Functional Joint Anatomy, Biomedical Engineering Laboratory Institute of Industry Incubation, Institute of Science, Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2927-2937","authenticated-orcid":false,"given":"Keiichi","family":"Akita","sequence":"additional","affiliation":[{"name":"Department of Clinical Anatomy Institute of Science, Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,27]]},"reference":[{"key":"e_1_2_12_2_1","volume-title":"Der Ano\u2010Rectale Lymphapparat","author":"Gerota D.","year":"1895"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/0090-4295(76)90550-1"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.173.3.2682777"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1090800303"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1090890304"},{"key":"e_1_2_12_7_1","volume-title":"Anatomical Basis of Clinical Practice","author":"Standring S.","year":"2020"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.200.1.8657951"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.168.3.9057506"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF02421375"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11255-015-1156-0"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.21037\/tcr-21-2467"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbmt.2012.02.005"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1111\/iju.14248"},{"key":"e_1_2_12_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/joa.13810"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00384-025-04890-1"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/bjs.18003714702"},{"key":"e_1_2_12_18_1","volume-title":"Hinman's Atlas of UroSurgical Anatomy","author":"MacLennan G.
