For patients, the diagnosis of testicular torsion is controversial and complicated by the fact that ultrasound blood flow signals are not significantly reduced in comparison to the unaffected, healthy, testis, despite persistent symptoms on the affected side. Our study aims to investigate the diagnostic characteristics of high-resolution ultrasonography (US) in pediatric testicular torsion with the preserved flow to increase diagnostic accuracy.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Seven pediatric patients aged 49 days to 15 years old, with the preserved blood flow, but surgically diagnosed as testicular torsion, from October 2017 to August 2019, were retrospectively included in the study. The imaging manifestations of high-frequency ultrasonography were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>All cases had preserved testicular blood flow, but the surgical findings showed various degrees of twist, from 90 to 540 degrees. Preoperative ultrasound showed spermatic cord distortion in all cases, and testicular long axis tilting in four cases (4\/7 = 57.1%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In some testicular torsion cases, Color Doppler may show normal or increased blood flow signals in the testis. We should further observe the morphology and position of the testes and epididymides, the echo of the testicular parenchyma, and, especially evaluate the \u201cwhirlpool sign\u201d in the spermatic cord, to avoid missing testicular torsion with blood flow signals.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fped.2022.1001958","type":"journal-article","created":{"date-parts":[[2022,9,28]],"date-time":"2022-09-28T02:41:13Z","timestamp":1664332873000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":16,"title":["The diagnostic value of ultrasound in pediatric testicular torsion with preserved flow"],"prefix":"10.3389","volume":"10","author":[{"given":"Zhihua","family":"Xu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junbo","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuangshuang","family":"Ni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongxia","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,9,28]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"996","DOI":"10.2214\/AJR.11.8034","article-title":"Sonography of the pediatric scrotum: emphasis on the Ts\u2013torsion, trauma, and tumors","volume":"198","author":"Sung","year":"2012","journal-title":"AJR."},{"key":"B2","doi-asserted-by":"publisher","first-page":"670","DOI":"10.1016\/j.urology.2011.10.041","article-title":"Clinical predictors of testicular torsion in children","volume":"79","author":"Boettcher","year":"2012","journal-title":"Urology."},{"key":"B3","doi-asserted-by":"publisher","first-page":"362","DOI":"10.1100\/tsw.2011.39","article-title":"Testicular torsion in children: a 20-year retrospective study in a single institution","volume":"11","author":"Yang","year":"2011","journal-title":"Scientific World J."},{"key":"B4","first-page":"8594","article-title":"Management of acute scrotum in children: a 25-year single center experience on 558 pediatric patients","volume":"23","author":"Pogoreli\u0107","year":"2016","journal-title":"Can J Urol."},{"key":"B5","doi-asserted-by":"publisher","first-page":"465","DOI":"10.1002\/bjs.1800630618","article-title":"Torsion of the testis and allied conditions","volume":"63","author":"Williamson","year":"1976","journal-title":"Br J Surg."},{"key":"B6","doi-asserted-by":"publisher","first-page":"563","DOI":"10.7863\/jum.2006.25.5.563","article-title":"Sonographic differential diagnosis of acute scrotum: real-time whirlpool sign, a key sign of torsion","volume":"25","author":"Vijayaraghavan","year":"2006","journal-title":"J Ultrasound Med."},{"key":"B7","doi-asserted-by":"publisher","first-page":"43","DOI":"10.1007\/BF00264627","article-title":"Experimental testicular torsion: effect on endocrine and exocrine function and contralateral testicular histology","volume":"16","author":"Janetschek","year":"1988","journal-title":"Urol Res."},{"key":"B8","doi-asserted-by":"publisher","first-page":"1159","DOI":"10.21037\/tau.2017.09.10","article-title":"Degree of twisting and duration of symptoms are prognostic factors of testis salvage during episodes of testicular torsion","volume":"6","author":"Howe","year":"2017","journal-title":"Transl Androl Urol."},{"key":"B9","doi-asserted-by":"publisher","first-page":"435","DOI":"10.1136\/bmj.312.7028.435","article-title":"ABC of general surgery in children.
