Clinical study of unilateral intravaginal testicular torsion and anatomicalcomparative study of bilateral testes in orchiopexy

摘要

Fourty-eight patients were operated on for unilateral intravaginal testicular torsion at Yokohama Red Cross Hospital during the period between July 1976 and December 2001. Orchiopexy was carried out on 20 out of 48 patients. Only 8 patients could receive orchiopexy within 8 hours after the onset of symptoms. Although, 24 of the 48 patients had visited a medical doctor within 8 hours after the onset. Therefore, the less the testes might be sacrificed if these patients could be immediately sent to a clinic with an urologic speciality. The contralateral uninvolved testis has been said to require orchiopexy because it has an anatomical structure similar to the testis with torsion. However, the contralateral testes in 5 out of 20 patients with ipsilateral orchiopexy turned out to have a normal anatomical structure according to our classification of intravaginal testicular torsion. This suggests that no orchiopexy is necessary if the contralateral uninvolved testis has a normal anatomical structure from the standpoint of torsion type.
