Computed Tomographic Study On the Pelvic Urethra in the Male Rabbit

Öz

The aim of the study was visualization and determination of some anatomic details of the pelvic urethra in the domestic rabbit, via computed axial tomography (CAT). The study was performed on 6 sexually matured and clinically healthy male New Zealand rabbits at age 18 months, with body mass 2.8 to 3.2 kg. As contrast matter was used OPTIRAY 350 (HEALTHCARE LTD. UK), applied parenterally (iv 1ml/kg m in vena cephalica), and the study was performing immediately. The second, used contrast material was UROGRAFIN 76% 20 ml (SCHERING LTD. GERMANY), applied perorally (per os) as 1.52 % water solution (30 ml/ kg, fractionally), the study was performed after three hours. We used axial computed tomograph
SIEMENS, SOMATOM, ARTX. The computed tomographic scan was marked cranially – by the caudal part of the body of ilium, in front of the acetabulum (laterally), in front of the pelvic brim (ventrally) and 1st sacral vertebra (S1 – dorsally), and caudally – by the body of ischium (laterally), behind pelvic arc (ventrally) and the end of 2nd coccygeal vertabra (Cg 2 – dorsally).
The thickness of the cuts was 2mm. The pelvic urethra of the male rabbit was depicted during the scan of the pelvis from the caudal part of 2nd sacral vertebra (dorsally), the middle of pubic symphysis (ventromedially) and the acetabular parts of corpus ossis ischii (dorsolaterally) to the 1st coccygeal vertebra (dorsally), the middle of ischial symphysis (ventrally) and the middle parts of the bodies of ischium (laterally).

Erkek Tavşanlarda Pelvik Üretra Üzerinde Kompütarize Tomografik Bir Çalışma

Öz

Bu çalışma ile, evcil tavşan urethra’sının pars pelvina’sının anatomik detaylarının CAT kullanılarak görüntülenmesi ve tanımlanması amaçlanmıştır. Çalışma, seksüel olgunluğa ulaşmış ve klinik olarak sağlıklı 18 aylık 6 adet erkek Yeni Zelanda tavşanında uygulanmış olup, tavşanların ortalama vücut ağılıkları 2,8 ile 3,2 kg arasındadır. Kontrast madde olarak OPTIRAY 350 (HEALTCARE LTD. UK) parenteral olarak (vena cephalica’dan i.v. 1 ml/kg) uygulanmış ve derhal çalışmaya geçilmiştir. İkinci olarak, kontrast madde olarak UROGRAFIN %76 20 ml (SCHERING LTD. GERMANY) %1.52 sulu solüsyonu oral (per os) olarak (30 ml/kg, azar azar) uygulanmış ve çalışma 3 saat sonrasında gerçekleştirilmiştir. ACT olarak SIEMENS, SOMATOM, ARTX cihazı kullanılmıştır. Bilgisayarlı tomografi taraması için cranial’den; corpus ossis ilii’nin caudal’i, acetabulum’un önü (lateral’den), apertura pelvis cranialis’in önü (ventral’den) ve birinci vertebra sacralis (dorsal’den) ile caudal’den; corpus ossis ischii (lateral’den), arcus pelvis (ischiadicus)’in gerisi (ventral’den) ve ikinci vertebra caudalis’in sonu (dorsal’den) işaretlendi. Kesit kalınlıkları 2 mm. olarak alındı. Erkek tavşanda urethra’nın pars pelvina’sı tarama sırasında ikinci vertebra sacralis’in caudal bölümünden (dorsal’den) symphysis pubis’in ortasına kadar (ventrolateral’den) ve corpus ossis ischii’nin acetabulum’un oluşumuna katılan kısmından (dorsolateral’den) birinci vertebra caudalis’e (dorsal’den) ve corpus ossis ischii’nin orta bölümünde tanımlanmıştır
