Experimental unilateral spermatic cord torsion has been shown to induce both ipsilateral and contralateral intratesticular biochemical changes indicative of hypoxia. An experimental study was conducted to see whether the presence of the ipsilateral testicular tissue is necessary for the occurrence
Contralateral testicular perfusion during unilateral testicular torsion was evaluated using simultaneous blood flow and O2 content determinations. Two groups, each consisting of 7 rats, were studied. Sham operation or 720 degrees clockwise twisting was performed on the left testes, and blood flow,
Testicular torsion is a surgical emergency mainly affecting adolescent boys, with a relatively high rate of missed torsion and testicular loss secondary to delay in prompt diagnosis and surgical intervention. With ischemic reperfusion injury as its underlying culprit, testicular OBJECTIVE
To evaluate contralateral testicular blood flow by histological examination of arterioles during ipsilateral testicular torsion.
METHODS
The study comprised two groups of 20 male albino rats (weight 250-270 g). The control group underwent a sham operation, while in the second group the
OBJECTIVE
Near infrared spectroscopy measures tissue oxygenation even when there is complete cessation of blood flow. We evaluated near infrared spectroscopy to diagnose testicular torsion and blindly compared its accuracy with that of Doppler ultrasound. We also compared it by immunohistochemical
Hypoxia-inducible factors (HIF) are transcription factors that serve essential regulatory roles in cellular and molecular responses to oxygen debt. HIFs are composed of hypoxia-dependent α subunits (1α, 2α, 3α) and an oxygen-independent β subunit. Previously we demonstrated that HIF-1, the master
This study was designed to determine the effect of molsidomine (MO), a precursor of nitric oxide (NO) donor, on hypoxia inducible factor alpha (HIF-1alpha) and Sonic hedgehog (Shh) levels considered to be involved in the development of testes ischemia/reperfusion (I-R) injury. Torsions were created
Spermatic cord torsion is a serious and common urologic emergency. It requires early diagnosis for prevention of subfertility and testicular necrosis. Vildagliptin and sitagliptin are anti-diabetic drugs of the dipeptidyl peptidase-4 (DPP-4) inhibitors that have a protective role against cerebral
Unilateral spermatic cord torsion in the presence or absence of ipsilateral testis causes hypoxia in the contralateral testis. An experimental study was conducted to find the most important structure that causes contralateral testicular hypoxia following ipsilateral twisting. In five groups each
Testicular torsion is a common urological emergency among adolescent boys and young men. Rotation of the testis and twisting of the spermatic cord rapidly leads to ischemia, resulting in a loss of germ cells. Thus, prompt diagnosis and urgent surgical intervention are required, but the subsequent
OBJECTIVE
To assess whether near-infrared spectroscopy can detect testicular hypoxia in a sheep model of testicular torsion within 6 hours of experimental torsion.
METHODS
This was a randomized, controlled, nonblinded study. Trans-scrotal, near-infrared, spectroscopy-derived testicular tissue
The most common causes of an 'acute scrotum' in childhood are testicular torsion, torsion of an appendix testis, epididyoorchitis, idiopathic edema, and hematoma. In rare cases a scrotal hematoma can originate from an extra- or intraperitoneal adrenal bleeding. 12 such cases have been described in
OBJECTIVE
To investigate primary lesions in twisted testes.
METHODS
The histologic study of testicular specimens obtained from men who had suffered testicular torsion.
METHODS
The conditions required for material selection were the knowledge of the exact time of torsion and the presence of
Mammalian spermatogenesis is a complex biological process occurring in the seminiferous tubules in the testis. This process represents a delicate balance between cell proliferation, differentiation, and apoptosis. In most mammals, the testicles are kept in the scrotum 2 to 7°C below body core
