On FSEB, benign diagnoses represented 58% of cases which allowed us to avoid 81 unnecessary radical orchidectomies. The sensitivity and specificity of FSEB for malignancy were 100% and 96.3%, respectively. Excluding three indeterminate cases on FSEB, the concordance rate was 97.7% (129\/132). On definitive assessment, the majority of cases were benign (84\/135, 62%) and 51 (38%) cases were malignant. The three indeterminate cases were ultimately confirmed as benign. There were three false\u2010positive diagnoses of (favoured) malignancy and no false negatives.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>FSEB is accurate for patient management of small testicular lesions, allowing us to save young men from unnecessary radical orchidectomy.
