LONG-TERM RESULTS OF OPERATIVE THERAPY OF MALDESCENSUS-TESTIS

304 patients born during 1961-1975 and treated for cryptorchidism betw een 1967 and 1988 were invited to a follow-up examination. The average age at therapy was 9.4 years. 98 patients could be examined. The volu me of all testes could be determined by sonography. The fertility stat us of 68 patients was known. Success regarding the position of the tes tes was very good with two exceptions (2 %). The average volume of the formerly undescended testes (7.9 ml) is strongly pathological, while the contralateral testes (11.3 ml) were also too small. 84.6 % of the patients with unilateral and only 50 % of those with bilateral cryptor chidism demonstrated sufficient fertility. There were no correlations between the age at therapy and the present testes volume or fertility.
