Use of intraoperative indocyanine green fluorescence in determining testicular viability in testicular torsion patients in rural settings: A case report

Abstract

Introduction and importanceTesticular torsion (TT) is the result of spermatic cord twisting which can lead to significant ischemia, making it a time-sensitive surgical emergency. General surgeons in rural centers may lack the resources to adequately evaluate the viability of the affected testicle. Indocyanine green fluorescence (IGF) has been increasingly used to assess vascular perfusion in general surgery cases. In this case report, we show the use of IGF in a rural setting to assess testicular viability in TT. Case presentationA 17-year-old male was transferred to our rural regional hospital emergency department for sudden and persistent right scrotal pain. The onset of symptoms was approximately 52 h at presentation. TT was diagnosed with a doppler ultrasound by a radiologist. Urgent detorsion surgery was performed. Intraoperative assessment of viability was unclear after the usual means and IGF helped confirm the absence of testicle vascularization and the need for orchiectomy. Clinical discussionGeneral surgeons in rural communities are called to manage TT with limited resources and experience. IGF is widely used in general surgery and urology. Animal studies and two case reports show potential benefits of IGF in TT. In our patient, IGF was useful to confirm without a doubt that the right testicle was ischemic and non-viable. ConclusionIn a rural setting with limited access to radiology and distant urology coverage, IGF is an excellent resource to determine intraoperative blood flow in TT with uncertain viability.
