Abstract

Introduction: Subfertilite rates remain high even though testis preserving management had been applied in patients with testicular torsion. The improvement ensured by Hyperbaric Oxygen (HBO) therapy on the injured tissue caused by ischemiac-reperfusion mechanism was shown in several different studies. On account of testicular tortion is an ischemia-reperfusion injury model we searched whether Hyperbaric Oxygen as an additional therapy will have a positive impact on testicular hystology in experimental testicular tortion. Materials and Methods: Spraque Dowley rats were divided into 5 groups, including 10 rats each. The right testes of rats were twisted 720 degree manually in a clockwise rotation after opening the scrotum and releasing the spermatic cord. Rats underwent a second surgical operation to provide the reperfusion; under general anesthesia the testes were detorsed manually and placed into their original place after reopening the scrotum. A 4 hour period of ischemia was applied in the ischemia group. In ischemia+reperfusion group a 24 hour period of reperfusion was applied after releasing the ischemia. In another group the rats were also underwent reperfusion after an ischemiac phase, but the duration of reperfusion was decided to be prolonged to 1 week instead of a 24 hour period. In HBO group following the ischemiac period, rats were anesthetized again and the testes were detorsed manually, thus reperfusion was restarted. Then, rats were taken into rooms used for research studies where pressure was carried out for duration of 1 week. The fifth group is the sham group. Both testes were analyzed hystopathologically after the procedures in all groups. Hystopathological examination was carried out under light microscopy according to the presumable morphological changes visible in the germinal epithelium and nucleus of germ cells. Results: In ischemia group a vesicular nuclear shape of spermatocytes was found. In ischemia+reperfusion group germinal epithelium disorganization and giant cells formed from degenerated sperms and spermatocytes were found as additional findings. In the group where reperfusion was prolonged to one week after a 4 hour period of ischemia, no different hystopathological finding was noted compared to the ischmeia+reperfusion group in which reperfusion was applied only for a 24 hour duration. In the HBO group vesicular nuclear shape of spermatocytes were also found but giant cells were seen rarely. Significant findings due to reperfusion injury were rarely recorded in this group. Conclusion: HBO treatment is an efficient additional therapy model after testicular preserving management in preventing testicular tissue damage in experimental testiculer tortion. Additional studies are needed to put this alternative treatment into clinical practice.

Özet

Testis koruyucu yaklaşımlara rağmen testis torsiyonlu hastaların uzun dönem takiplerinde subfertilite oranları yüksek seyretmektedir. Hiperbarik Oksijen (HBO) tedavisinin iskemik-repefüzyon hasarının yol açtığı doku tahribatlarında iyileştirici etkisi birçok çalışmada gösterilmiştir. Testis torsiyonu bir iskemi-reperfüzyon hasarı modeli olduğundan deneysel testiküler torsiyonda hiperbarik oksijen tedavisinin detorsiyon sonrası olası pozitif etkinliğini araştırdık. Çalışmada Spraque Dowley sıçanları 10’arlı 5 gruba ayrıldı. Torsiyon işlemi skrotum açılıp, spermatik kord serbestlendikten sonra sağ testis saatle aynı yönde (clockwise) 720 derece manuel yolla döndürülerek gerçekleştirildi. Reperfüzyon işlemi için sıçanlar yeniden anestezi altına alındı ve skrotal insizyonu takiben testisler manuel olarak detorsiyone edilip skrotuma yeniden yerleştirildi. İskemi grubunda sadece 4 saatlik iskemi uygulanırken, iskemi+ reperfüzyon grubunda iskemiyi takiben detorsiyon işlemi ile 24 saat boyunca reperfüzyon uygulandı. Diğer bir grupta aynı şekilde iskemi süresini takiben sıçanlar reperfüzyon işlemine alındı. Ancak reperfüzyon süresi 24 saat yerine 1 hafta olarak belirlendi. HBO uygulanan grupta ise iskemi periodunu takiben sıçanlar yeniden anestezi altına alınıp, detorsiyone edilip reperfüzyon yeniden başlatıldı. Daha sonra araştırma amaçlı kullanılan basınç odasına alınıp 1 hafta süreyle HBO uygulandı. 5. grup sham grubu olup tüm gruplarda işlemlerin sonunda her iki testis histopatolojik olarak incelendi. İnceleme; ışık mikroskopu altında germinal epitelyum ve germ hücre çekirdeklerinde meydana gelebilecek morfolojik değişikliklere göre yapıldı. İskemi grubunda spermatositlerde çekirdekte veziküler görünüm saptanırken iskemi+reperfüzyon grubunda bu bulgulara ek olarak germinal epitelyumunda disorganizasyon, ayrışma ve lümene dökülme ve dejenere spermlerde ve spermatositlerde dev hücre formasyonu gözlendi. Reperfüzyon süresinin 1 hafta olarak belirlendiği grupta 24 saat reperfüzyonun uygulandığı iskemi+reperfüzyon grubundan daha farklı bulgulara rastlanılmadı. HBO uygulanan grupta ise nadir dev hücre formasyonu gözlendi. Bu grupta reperfüzyon ile ortaya çıkan ağır histopatolojik özelliklere seyrek olarak rastlanıldı. Deneysel torsion modelinde HBO tedavisi testiküler doku hasarını önlemede testis koruyucu girişimler sonrası uygulanabilecek etkili ek bir tedavi yöntemidir. Klinik uygulama için ek çalışmalara ihtiyaç vardır.
