We studied the usefulness of radiography for localization of cryptorchid testes. A total of 23 radiographic studies ordered by referring physicians was done for testis localization in 18 boys. Two patients had retractile testes and were followed expectantly. Ultrasonography failed to detect palpable testes in both cases. A total of 16 boys (19 undescended testes) underwent operative exploration and the findings were compared. Ultrasonography correlated with the operative findings in 7 of 12 cryptorchid testes (58%), while computerized tomography and magnetic resonance imaging correlated in only 4 of 12 (33%) and 0 of 1 (0%), respectively. The overall accuracy of radiological testing was 44%. Physical examination was 53% accurate when performed by the referring physician and 84% accurate when done by the attending pediatric urologist. In no case did radiographic assessment influence the decision to operate, the surgical approach or the viability/salvageability of the involved testes. Preoperative radiography for undescended testes is neither necessary nor helpful.
