Learning objectives Highlight Doppler ultrasound as the first-line modality for evaluating acute scrotum. Define normal scrotal sonographic anatomy as a reference for identifying acute pathology. Describe the main causes of acute scrotal pain, highlighting key B-mode and Doppler features and differential patterns.
Read more Background Acute scrotum is a time-critical urological emergency characterised by sudden pain, swelling, and erythema. As clinical findings are often non-specific, Doppler ultrasound is the first-line modality, enabling rapid assessment of testicular morphology, perfusion, and differentiation between non-ischaemic and ischaemic causes.
Read more Findings and procedure details EMBRYOLOGYThe testes originate from the gonadal ridge, derived from intermediate mesoderm. Initially located in the posterior abdominal wall, they descend through the inguinal canal into the scrotum guided by the gubernaculum testis, carrying layers of the abdominal wall that form the testicular coverings. [fig 1] ULTRASOUND ANATOMY OF THE TESTES The testes, suspended in the scrotum, are ovoid and obliquely oriented, with the left usually slightly lower. On ultrasound, adult testes measure 3–5 cm in length, 2–4 cm in width, ~3 cm anteroposteriorly, with an average...
Read more Conclusion Ultrasound is the cornerstone for acute scrotum, distinguishing emergencies from self-limiting conditions. A structured, anatomy-based approach enhances diagnostic confidence, decision-making, and patient outcomes.
