The dorsal artery and veins are ligated and the tourniquet is removed;a gush of blood from the erectile tissue generally follows, but, as a rule,the bleeding ceases almost immediately. Occasionally the cavernousarteries will require ligation. The urethra is now divided for at least one-quarter of an inch on the floor of the canal. The skin is pulled over theend of the stump, and two interrupted sutures are applied, one at each.

The urethra is next sutured to the margin of the skin, so thatwhen the operation is completed, the urethral opening is spread out andhas a large roomy orifice. A soft-rubber catheter is inserted, and con-tinuous drainage established until union takes place. Extirpation of the Penis.—If there is glandular involvement, theglands are first removed, after the following manner, suggested byCurtis. An incision is begun on one side, parallel to Pouparts ligament,a,nd continued across the pubic bone to the groin of the opposite upper and a lower skin-flap are dissected a little distance beyond thediseased glands. The incision is then carried downward until the fasciaof the external oblique is reached
