An inguinal sonogram often is obtained in boys with a nonpalpable testis to \u201clocalize\u201d the testis, ie, determine whether the testis is present. The results of ultrasonography in boys with a nonpalpable testis were analyzed.<\/jats:p>\n               <jats:p>Methods. The records of boys who were referred to a pediatric urology center with a diagnosis of nonpalpable testis and who had undergone inguinal sonography were reviewed. The results of sonography were compared with findings in the office as well as surgical findings.<\/jats:p>\n               <jats:p>Results. A total of 62 boys who were referred with a diagnosis of a nonpalpable testis and who had undergone a sonogram were reviewed. The sonogram was ordered by the primary care physician in 51 boys (82%) and by a general urologist in 11 cases (18%). The testis was identified by sonography in 12 (18%) of 66 cases, and all were localized to the inguinal canal. Physical examination by a pediatric urologist showed that 6 were in the scrotum and 6 were in the inguinal canal or perineum. Of the 54 testes that were not localized by the sonogram, 33 (61%) were palpable and 21 (39%) were nonpalpable. Of the truly nonpalpable testes, laparoscopy and abdominal\/inguinal exploration identified the testis as abdominal in 10 cases and atrophic secondary to spermatic cord torsion in 11 cases.<\/jats:p>\n               <jats:p>Conclusion. Sonography is unnecessary in boys with a nonpalpable testis, because it rarely if ever localizes a true nonpalpable testis, and it does not alter the surgical approach in these patients.<\/jats:p>","DOI":"10.1542\/peds.110.4.748","type":"journal-article","created":{"date-parts":[[2004,8,14]],"date-time":"2004-08-14T00:17:55Z","timestamp":1092442675000},"page":"748-751","source":"Crossref","is-referenced-by-count":89,"title":["Ultrasonography Is Unnecessary in Evaluating Boys With a Nonpalpable Testis"],"prefix":"10.1542","volume":"110","author":[{"given":"Jack S.","family":"Elder","sequence":"first","affiliation":[{"name":"From the Division of Pediatric Urology, Rainbow Babies and Children\u2019s Hospital, Department of Urology, Case Western Reserve University School of Medicine, Cleveland, Ohio"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2002,10,1]]},"reference":[{"key":"2021121006402471700_R1","doi-asserted-by":"crossref","unstructured":"Elder JS.
