“The surgeon got to work. First he inserted a thin silver instrument, the itinerarium, through the penis into the bladder to help position the stone. Then he made the incision, about three inches long and a finger’s breadth from the line running between scrotum and anus, and into the neck of the bladder, or just below it. The patient’s face was sponged as the incision was made. The stone was sought, found and grasped with pincers; the more speedily it could be got out the better. Once out, the wound was not stitched—it was thought best to let it drain and cicatrize itself—but simply washed and covered with a dressing, or even kept open at first with a small roll of soft cloth known as a tent, dipped in egg white. A plaster of egg yolk, rose vinegar and anointing oils was then applied.”
Pity things have moved on since Pepys's time..
