Zhang Fan's scheduled prostatectomy was the first scheduled surgery of the day. The urology department had a special endoscopic surgery room of its own where the department nurses took turns being the operating room nurses.

Also, the doctor would need to wear a special waterproof plastic surgical outfit.
