I agree with Claudia Letizia that SOD stands for Struttura Organizzativa Dipartimentale and I would translate it just as Department.

SOD Medicina stands for medical department.

I assume this is a department within a hospital or similar organisation, therefore, I don't think you need to translate medical here, e.g.:

Please call the Andrology department

Andrology

The term Andrology is derived from the Greek word Andros, or man, and is the medical speciality that deals with problems of the male reproductive system.

Andrology Services

Andrology is an integral part of the Cellular Pathology Department.

We hold clinics at both the Royal Blackburn Hospital and Burnley General Hospital sites.
