“…In a larger multicenter study of 919 patients with an acute scrotum, HRUS was used to detect spermatic cord torsion in 199 of 208 patients with surgically proven testicular torsion (96% sensitivity), compared with 158 confirmed on CDS (sensitivity 76%). 32 Whilst HRUS revealed a linear cord in the remaining 711 patients (99% specificity), the authors did show that increasing reliability correlated with the degree of experience by the radiologist, and that visualization of a spermatic cord twist is difficult in very high or inguinal testes.…”

“…Though color Doppler US is a reliable test in the diagnosis of TT, falsenegative results can be seen. Kalfa et al (19) described the advantages of high-resolution US (HRUS) which enables direct visualization of the rotation of spermatic cord. In a study performed on 919 patients, the sensitivity of color Doppler US was determined as 76%, while sensitivity and specificity of HRUS were 96% and 99%, respectively (3).…”

Aim: Testicular torsion (TT) is one of the most important causes of acute scrotum in children and young men. Very scarce number of serum laboratory parameters might be used in the early diagnosis of patients with TT. We planned this study in consideration of the possible significance of the changes in serum irisin and visfatin levels in the diagnosis of TT. Methods:We used 28 rats in four groups. In the control group, blood samples and specimens of testicular tissue were collected at 2 nd and 4 th hours after torsion. In the torsion groups, the left testis was twisted, and blood samples and specimens of the testicular tissue were collected at the 2 nd and 4 th hours for analysis.Results: There was no statistically significant difference in mean irisin and visfatin levels at the 2 nd and 4 th hours between rats with TT and controls. There was no statistically difference between mean irisin and vistatin levels at the 2 nd hour and at the 4 th hour in torsion and control groups. Conclusion:In our experimental TT method, we could not find a statistically significant difference between serum levels of irisin and visfatin. We assume that further studies are needed on this issue. Keywords: Testicular torsion, experimental, irisin, visfatinAmaç: Testis torsiyonu (TT) çocuklar ve genç erkeklerdeki akut skrotumun en önemli nedenlerinden biridir. TT'li hastalarda erken tanıda kullanılabilecek serum laboratuvar parametreleri oldukça sınırlıdır. Biz de bu çalışmamızı, TT tanısında irisin ve visfatin'in serum düzeylerindeki değişimin anlamlı olabileceğini düşünerek planladık.Yöntemler: Çalışmamızda dört grupta 28 sıçan kullanıldı. Kontrol gruplarında gubernakulum ortaya konduktan sonra 2. ve 4. saatlerde kan ve testis dokuları alındı. Torsiyon gruplarında ise sol testise torsiyon uygulandıktan sonra 2. ve 4. saatlerde kan ve testis dokuları inceleme için alındı. Bulgular: TT olan ratlarda 2. ve 4. saat irisin ve visfatin değerlerinin ortalamalarında kontrol grubuna göre anlamlı fark saptanmadı. Torsiyon grubu ve kontrol gruplarının 4. saatteki irisin ve visfatin ortalamaları ile 2. saat ortalamaları arasında da istatistiksel olarak anlamlı fark saptanmadı. Sonuç:Oluşturduğumuz deneysel TT modelinde, irisin ve visfatinin serum düzeylerinde istatistiksel olarak anlamlı fark bulamadık. Bu konuda ek çalışmalara ihtiyaç olduğunu düşünmekteyiz.

“…Normal intra-testicular perfusion does not exclude the possibility of torsion and there remains a falsenegative rate in this modality. 51,52 As a missed diagnosis of testicular torsion is one of the most common medicolegal claims in adolescent patients in the United States, 53 we must stress again the prime importance of clinical evaluation and decision. Nuclear scintigraphy and MRI are not popular for the same reason.…”
