US findings of whirlpool\u00a0sign, testicular volume ratio, heterogeneous echotexture, testicular vascularity, epididymis enlargement and\/or hyperemia, and\u00a0avascular nodule were evaluated and compared. A decision tree model was created using the conditional inference tree analysis\u00a0and the accuracy was calculated. Univariate logistic regression analysis was performed to find out the predictive US features of\u00a0unsalvageable testes.Results: Total of 381 patients (13.2\u00b17.2 years old; range, 1 day-30 years) were included. Thirty-four patients\u00a0were diagnosed with testicular torsion, and the others with orchitis or epididymo-orchitis (n=59), epididymitis (n=264),\u00a0and appendage torsion (n=24). In the conditional inference tree analysis, whirlpool sign, avascular nodule, and increased\u00a0testicular vascularity were the most significant discriminators (p&lt;0.001), and the whirlpool sign was the first discriminator.\u00a0The overall accuracy of the conditional inference tree was 91.1% (95% confidence interval [CI], 87.8-93.7%). Heterogeneous\u00a0echotexture (odds ratio [OR], 74.99; 95% CI, 2.75-2046.26; p=0.01) and symptom-to-operation time &gt;24 h (OR, 49.28; 95%\u00a0CI, 1.92-1262.03; p=0.02) were significant predictors of unsalvageable testis.Conclusions: Conditional inference tree analysis\u00a0showed that the whirlpool sign of the spermatic cord, avascular nodule, and altered testicular vascularity were significant\u00a0discriminators. Heterogeneous echotexture and symptom-to-operation delay were important prognostic factors for unsalvageable\u00a0testis.<\/jats:p>","DOI":"10.11152\/mu-3507","type":"journal-article","created":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T15:23:26Z","timestamp":1650986606000},"source":"Crossref","is-referenced-by-count":1,"title":["A simplified ultrasound approach to diagnose testicular torsion and predict unsalvageable testis"],"prefix":"10.11152","author":[{"given":"Yunji","family":"Lim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jisun","family":"Hwang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joonsuk","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Chul","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seon Jeong","family":"Min","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4840","published-online":{"date-parts":[[2022,4,18]]},"container-title":["Medical Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3507\/1958","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3507\/1959","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3507\/1960","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/viewFile\/3507\/1960","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,4,26]],"date-time":"2022-04-26T15:24:08Z","timestamp":1650986648000},"score":1,"resource":{"primary":{"URL":"https:\/\/medultrason.ro\/medultrason\/index.php\/medultrason\/article\/view\/3507"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4,18]]},"references-count":0,"URL":"https:\/\/doi.org\/10.11152\/mu-3507","relation":{},"ISSN":["2066-8643","1844-4172"],"issn-type":[{"value":"2066-8643","type":"electronic"},{"value":"1844-4172","type":"print"}],"subject":[],"published":{"date-parts":[[2022,4,18]]}}}
