This dedicated imaging confirmed HK with a heterogeneously enhancing right upper pole 3.1 cm\u00d73.7 cm\u00d72.7\u2009cm mass. Due to suspicion for aberrant vasculature on CECT, renovascular angiography was performed, which revealed recruitment of a right paravertebral vessel alongside two right renal moiety arteries and multiple right renal moiety veins. Based on vascular complexity and the surgical exposure required for arterial clamping, open transperitoneal right partial nephrectomy was preferred to minimally invasive techniques. Postoperative course was complicated by ileus, which resolved with standard management. Pathologic analysis revealed complete resection of a 5.0\u2009cm Fuhrman grade II clear cell renal cell carcinoma.<\/jats:p>","DOI":"10.1136\/bcr-2020-235928","type":"journal-article","created":{"date-parts":[[2021,5,14]],"date-time":"2021-05-14T11:16:27Z","timestamp":1620990987000},"page":"e235928","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Open transperitoneal partial nephrectomy in a horseshoe kidney"],"prefix":"10.1136","volume":"14","author":[{"given":"Alex","family":"Romeo","sequence":"first","affiliation":[{"name":"Geisinger Commonwealth School of Medicine, Scranton, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0897-9220","authenticated-orcid":false,"given":"Evan","family":"Spencer","sequence":"additional","affiliation":[{"name":"Geisinger Commonwealth School of Medicine, Scranton, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"Baber","sequence":"additional","affiliation":[{"name":"Geisinger Northeast Urology Department, Wilkes-Barre, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Ferretti","sequence":"additional","affiliation":[{"name":"Geisinger Northeast Urology Department, Wilkes-Barre, Pennsylvania, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,14]]},"reference":[{"key":"2025082803054480000_14.5.e235928.1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21590"},{"key":"2025082803054480000_14.5.e235928.2","doi-asserted-by":"publisher","DOI":"10.1097\/01.ju.0000092537.96414.4a"},{"key":"2025082803054480000_14.5.e235928.3","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2006-1374"},{"key":"2025082803054480000_14.5.e235928.4","first-page":"31","article-title":"Retroperitoneoscopic partial nephrectomy for a horseshoe kidney tumor","volume":"13","author":"Nikoleishvili","year":"2017","journal-title":"Urol Case Rep"},{"key":"2025082803054480000_14.5.e235928.5","first-page":"100902","article-title":"Renal cell carcinoma in a horseshoe kidney treated with robot-assisted partial nephrectomy","volume":"25","author":"Yamamichi","year":"2019","journal-title":"Urol Case Rep"},{"key":"2025082803054480000_14.5.e235928.6","doi-asserted-by":"crossref","first-page":"e2175","DOI":"10.1016\/S1569-9056(17)31332-5","article-title":"Partial nephrectomy of horseshoe kidney with renal cell carcinoma localized in the isthmus and the lower poles of both parts: a case report","volume":"16","author":"Grygorenko","year":"2017","journal-title":"European Urology Supplements"},{"key":"2025082803054480000_14.5.e235928.7","first-page":"1","article-title":"A rare case of a renal cell carcinoma confined to the isthmus of a horseshoe kidney","volume":"2015","author":"Kongnyuy","year":"2015","journal-title":"Case Rep Urol"},{"key":"2025082803054480000_14.5.e235928.8","unstructured":"National Comprehensive Cancer Network .
