2.3 Ultrasound examination
The findings of the physical examination can be complemented or verified by means of ultrasound. For example, using sonography the doctor can clearly diagnose a femoral hernia which is scarcely palpable. Likewise, using this technique he can distinguish between a scrotal hernia (testicular hernia with displacement of intestinal structures into the scrotum) and a hydrocele (fluid accumulation in the scrotum).
Ultrasound examination causes the patient no pain at all and is very gentle since no X-ray beams are used. The latest equipment produces precise images of the inside of the body, where even small changes in organs can be detected.
