精巣捻転症例における精巣白膜減張切開術の検討

Abstract

Between November 2011 and November 2014, we performed a tunica albuginea incision with tunica vaginalis flap coverage (TAI＋TVFC) on 5 out of 15 patients who underwent surgery for testicular torsion. Of those 15 patients, 7 underwent orchidopexy alone (Group A), 5 underwent TAI＋TVFC (Group B), and 3 underwent an orchidectomy procedure (Group C). All were followed for 1 year and preservation of testicular volume ＞50% on the contralateral side in ultrasound measurements was considered as salvaged. During the follow-up examinations, no testicular atrophy was noted in Group A. In Group B, tension and testis color were immediately improved in all 5 patients after TAI＋TVFC, while blood perfusion was also improved after the operation. Also 3 patients in Group B were considered to be salvaged, while testicular atrophy occurred in 2 after 8 or more hours from onset until surgery. Our results indicated that TAI＋ TVFC is useful for restoring blood flow after surgery for testicular torsion, although the so-called‘Golden time’for torsion surgery has a significant impact in such cases.
