Nonpalpable testes: is there a relationship between ultrasonographic and operative findings?

ABSTRACT: BACKGROUND: Ultrasonography (US) as a diagnostic tool in the work-up of boys with nonpalpable testes (NPT) is still controversial. OBJECTIVE: To evaluate the relation between US and operative findings in boys with NPT. MATERIALS AND METHODS: During a 7-year period we saw 135 boys with 152 NPT. All were examined by the referring physician or a paediatric surgeon, underwent US examination, and were then re-examined afterwards by a specialist. Finally, all boys were surgically explored for testicular position. RESULTS: US located 103 NPT (68%), 16 within the abdomen and 87 in the inguinal canal. With knowledge of the US result, 37 testes were palpable on re-examination. The sensitivity of US was 97% for inguinal and 48% for abdominal viable testes. Of the 49 testes (32%) missed by US, 16 were viable in either the abdominal (n=14) or the inguinal (n=2) position. CONCLUSION: All boys with presumed NPT should be referred to a specialist. US is useful to determine localization of NPT, which facilitates planning the surgical procedure. An inguinal exploration is called for when US identifies the testis in the inguinal canal. Because the sensitivity of US for viable abdominal testes is only 48%, we now always perform laparoscopic exploration when US is negative.

Project description:ObjectiveDescribe detailed histopathologic findings from a cohort of patients with chronic rhinosinusitis and evaluate whether histologic measures correlate with baseline clinical factors.Study designCross-sectional study with planned data collection.SettingTertiary medical center.Subjects and methodsAdult patients with chronic rhinosinusitis were prospectively enrolled and demographic data and medical comorbidities recorded. Disease severity was measured by computed tomography (CT), endoscopy, Smell Identification Test (SIT), the Chronic Sinusitis Survey, Rhinosinusitis Disability Index, and SF-36 General Health Survey. Mucosal specimens were assessed for the presence of mucosal inflammation, including cellular (eosinophils, neutrophils, lymphocytes, mast cells, plasma cells, macrophages), epithelial (squamous metaplasia, basement membrane thickening, goblet cells), and stromal markers (subepithelial edema, fibrosis). Histopathologic findings were correlated to baseline clinical factors.ResultsA total of 147 subjects were enrolled with histologic samples available for review. Presence of inflammatory markers was diverse, with lymphocytes present in 100 percent of subjects, eosinophils in 49.7 percent, and neutrophils found in 0.7 percent. Total eosinophil counts correlated with the presence of nasal polyposis (r = -0.367; P < 0.001), asthma (r = 0.264; P = 0.001), and aspirin intolerance (r = 0.279; P = 0.001). Mucosal eosinophilia correlated with worse disease severity on CT (r = 0.414; P < 0.001), endoscopy (r = 0.376; P < 0.001), and SIT (r = -0.253; P = 0.002), with the highest correlations seen in subgroups without nasal polyps. Histopathologic findings did not significantly correlate with any quality-of-life measure.ConclusionMucosal eosinophilia correlates with objective disease severity as defined by CT, endoscopy, and SIT scores. Although other histologic markers of inflammation are present, none show similar correlations. The presence of mucosal eosinophils does not correlate with quality-of-life scores.
