The blind-ending vas: the fate of the contralateral testis.
From August 1980 to January 1983, 48 testes were explored for orchiopexy (28 unilateral and 20 bilateral testes). Unilateral anorchism (surgically identified blind-ending vas and vessels) was found in 7 of 48 cases (14.5 per cent). One simultaneous and 5 secondary contralateral scrotal explorations confirmed abnormal testicular fixation (bell-clapper deformity) in 5 of 6 testes (83 per cent). During documentation of unilateral anorchism, simultaneous contralateral scrotal exploration should be performed.
