The management of the impalpable testis by surgery alone

We evaluated 68 prepubertal boys with 84 impalpable testes who were operated upon without using any other diagnostic maneuvers. Of the testes 18 (22%) were absent (anorchism or 'vanished') and 38 (45%) could be placed in a scrotal position with standard orchiopexy. A staged, Fowler-Stephens or microvascular procedure was required for 28 testes (33%), involving orchiectomy in 2 cases, and succeeded in a scrotal position for another 24 testes. In 1 boy 2 testes were fixed outside the inguinal canal. Reexamination after 3 to 9 years showed that 42 of 55 operated testes (76%) were in scrotal position without atrophy, 10 had atrophied and 3 were removed at the second stage operation. We conclude that an exclusive surgical approach has the advantage of providing diagnosis and therapy, and, therefore, it is an effective method.
