URETHRAL ANOMALIES.
Imperforations. In the new born male, foal, lamb, etc. Usually at the outer end, and it may be for some distance back. In one case the sheath was firmly adherent on the wall of the abdomen, thus shutting off all exit of urine. If the canal is absent only at the orifice or for a short distance, the urethra beyond this can be felt full of liquid and fluctuating. The patient being properly fixed a fine trochar is pushed from the end of the penis into the blind end of the urethra, which will be ascertained by the overcoming of resistance. The trochar is now withdrawn and the urine flows through the cannula. A catheter or sound is now tied in the passage to maintain it pervious until cicatrization shall have taken place.
Hypospadias. Short urethra opening backward on the lower surface of the penis. Considered irremediable.
Epispadias. Urethra opening on the upper surface of the penis. Much more rare.
