We investigated the usefulness of transscrotal near infrared spectroscopy that measures testicular oxygen saturation (StO 2 %) in the diagnosis of testicular torsion vs other causes of the acute scrotum in adults. Between January and May 2009, 16 adult males presenting with acute scrotum underwent StO 2 % measurement of the affected and unaffected testis using near infrared spectroscopy...
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 evaluation of hypoxia and cell viability. Rats were randomized to 4 groups, including group 1—720-degree unilateral...
