Abstract :

A male goat with significant penis sheath distension and lack of urine, 48 hours after birth was referred to the Large Animal Clinic of veterinary Faculty of Islamic Azad University of Tabriz. With puncture, pale yellow serous fluid with urine like smell was removed from the distended site. In preliminary examinations, ruptured urethra was tentatively and prineal urethrotomy was performed. After urethral catheterization urethral obstruction near the end of urethra and in intraoperative investigation diagnosed was performed absence of part of the penis and urethra (that does not allow the urinary catheterisation) was determined. With separation of urethra the from adjacent tissues permanent prineal uretherostomy in order to create the ability to urinate, the urethra opened and its edges sutured to the external surfaces of skin and fixed. Fluid therapy and antibiotic therapy was performed postoperatively. In follow-up after surgery, there was no distension and inflammation and the goat was in perfect health. Congenital aplasia of the urethra with penile segmental aplasia is rare cases with very low occurrence in domestic animals.
