[Surgical technique in the management of undescenced testis (author's transl)].

In cases of retentio abdominalis or inguinalis and of ectopic testis, surgery is performed about the 2nd year of life. Essentials of the operating technique are: incision of the skin must not be parallel to the spermatic cord; testes and spermatic cord must be mobilized without trauma; ideally a biopsy of the testis should be taken; any pulling of the spermatic cord and torsion of it during fixation of the testis should be avoided. If initial tensionfree placement of the testis in the scrotum is impossible, the operation should be carried out in 2 sessions with an interval of 6-12 months. In 241 cases of children operated on from 1972-1975 with 308 total operations, the author observed 2 recurrences and 1 deep infection (scrotal abscess).
