Hypospadias in goats

هايپوسپاديازيس يك نقص مادرزادي غيرمعمول در مجراي ادراري حيوانات مزرعه مي باشد، علت وقوع اين عارضه به درستي تشخيص داده نشده است و بنظر مي رسد مرتبط با عوامل ژنتيكي، فاكتورهاي اندوكرايني و فاكتورهاي محيطي مي باشد. از مهرماه سال نود و هفت تا مهر ماه نود هشت تعداد 8 راس بزغاله هاي با دامنه سني يك تا سه هفته با علايم اين عارضه ( تجمع ادرار در قسمت بافت زيرجلدي ناحيه pre scrotal ) به بيمارستان آموزشي پژوهشي دانشكده دامپزشكي دانشگاه شهيد باهنر كرمان ارجاع داده شد.بعد از ارجاع بيماران به بخش جراحي، پس از تزريق داروي بي حسي موضعي، يك شكاف در موضع موردنظر ايجاد و پس از تخليه ي ادرار يك سوراخ جهت خروج ادرار در ناحيه pre scrotal باقي گذاشته شد و مابقي پوست ناحيه جهت جلوگيري از بسته شدن مجدد محل برش با نخ نايلون 0-2 و با الگوي ساده تكي بخيه زده شد.

Hypospadias is an uncommon congenital defect of urinary tract in farm animals. This defect has been recorded rarely in calves, lambs and foals in the world. The aetiology of hypospadias is not well understood, it seems to be multifactorial and may be related to genetic, endocrinological, and environmental factors. During Octobr 2019 to October 2020, some goat kids with sings of hypospadias were referred to the Veterinary Hospital of Kerman University, Iran. The age of patients ranged from one week to three months old. Penile and testicular hypoplasia were observed in all of them. In one case, ectopic penis (between anus and scrotum) was found. In one goat, opening of the urethra was located in the scrotal region and in the others it was in the penile position. Urine had leaked into the subcutaneous tissue of the ventral abdominal wall and prepuce but the skin of the swollen area was normal and no signs of urine scalding were visible. For the treatment of patients, penile urethrostomy at the proximal region of the defect was performed by suturing the urethral epithelium to the skin with 2-0 nylon sutures in a simple interrupted pattern. There was no complaint about postoperative complications from goat’s owners.
