Use of infrared thermal camera in acute scrotal pain: a prospective study

Abstract

Background and objectives: Infrared thermal (IR) camera is used to assess various clinical conditions such as diabetic foot, carotid artery stenosis, and superficial infection. The present study was designed to determine the usefulness of IR thermal camera in scrotal temperature measurement before color Doppler ultrasonography (CDUS) in patients admitted to the emergency department with acute scrotal pain. Method: This study was prospectively conducted on 49 patients with acute scrotal pain and 30 control participants. The findings of CDUS and scrotal temperature measurements by an IR camera were separately evaluated by different physicians. In all patients, temperature measurements with IR camera were made under the same environmental conditions. Results: Of the 49 patients included in the study, four were diagnosed with torsion, 12 with epididymitis, 4 with orchitis, 3 with epididymo-orchitis, and 2 with varicocele. A significant difference was observed between the scrotal temperature of the patients with scrotal pain and the mean testicular temperature of the control group based on the IR camera measurement (p<0.05). IR camera did not detect any difference between the two testicles of the same person in the patient group (p=0.615). Although the lowest temperature was in testicular torsion, the patients’ scrotal temperature did not significantly differ according to their diagnoses (p=0.087). Conclusion: Testicular temperature measured by IR device was lower in patients presenting with scrotal pain compared to normal individuals. Although not statistically significant, the lowest temperature was found in cases of testicular torsion. IR camera may be useful in triage when used in conjunction with physical examination in patients presenting with acute scrotal pain. IMC J Med Sci 2022; 16(1): 007.
