Tavşanda urethra’nın postprostatik bölümünün bilgisayarlı tomografik anatomisi

Year 2015, Volume: 4 Issue: 1, 382 - 386, 01.01.2015

Abstract

Özbilgi/Amaç: Erkek hayvanlarda urethra, pars pelvina ve pars penina olmak üzere iki bölümde incelenir. Pars pelvina ise pars preprostatica ve pars prostatica urethra olma üzere ikiye ayrılır. Bu çalışmanın amacı tavşanlarda postprostatik urethra’nın bilgisayarlı tomografik görüntülerinin sunulmasıdır. Materyal ve Metot: Bu çalışmada 10 adet sağlıklı erkek Yeni zellanda tavşanı kullanıldı. Hayvanlar anesteziye alındı. Tomografik görüntülerde kemik bölgeleri belirlendi. Oral ve parenteral yolla kontrast madde verildi. Çok kesitli helikal bilgisayarlı tomografi ile tüm vücut tarandı. Bulgular ve Sonuç: Pelvis bölgesinin üçüncü ve dördüncü sacral vertebra ve birinci caudal vertebra hizasından geçen transversal tomografik kesitlerinde, öncelikle corpus osssis ischii ve symphysis ischiadica belirlendi. Bunu takiben sypmhisis’in dorsalinde düşük yoğunlukta urethra lumeni belirlendi. Lumenin şekli, kenarları belirgin dorsoventral yönlü düzleşen ovoid olarak belirlendi, Urethra duvarı daha çevresindeki yumuşak dokulara göre daha yüksek yoğunlukta görülüyordu. Bu çalışmada kullanılan metot ile postprotatik urethra detaylı bir şekilde görüntülenebilmiştir..

Anatomical Transverse Helical CT Study of The Postprostate Part of The Rabbit Urethra

Year 2015, Volume: 4 Issue: 1, 382 - 386, 01.01.2015

Abstract

Background/Aim: The male urethra in domestic mammals is composed of pelvic and penile part. The pelvic part consists of preprostate and prostate part.The aim of the study was to present data for helical СТ visualization of the rabbit postprostate urethra. Material and Method: Ten mature clinically healthy male New Zealand white rabbits were studied. The animals were anesthetized. The bone landmarks at the helical СТ study were identified. The peroral and parenteral contrast agents were administered. A whole body multi-slice helical computed tomography scanner was used. Result and Conclusion: СТ scan of the pelvis in the transverse plane through the third, fourth sacral and first coccygeal vertebra, body of ischiadic and ischiadic symphysis visualized the following: urethral hypoattenuated lumen was dorsal to the pelvic symphysis; the urethral lumen’s shape was ovoid with regular contours and flattened dorsoventral; the urethral wall was relatively hyperattenuated, compared to the close soft tissues, except the rectal finding. The study creates a detail picture for the postprostate urethra that shows the method’s benefits.
