Abstract

The Compulsory Supervised Internship (ESO) is a discipline that is part of the curriculum and is compulsory for graduation in Veterinary Medicine at the Federal Rural University of Pernambuco. The required workload for this course is 420 hours. ESO began on September 18, 2018 and ended on December 5, 2018, and was held at the Veterinary Hospital of the Federal Rural University of Pernambuco, focusing on Small Animal Surgery. The daily workload consisted of 8 hours per week, divided between the Surgical Technique classes (theoretical and practical) and the hospital's routine of surgery. The experience provided the daily experience of care and procedures that greatly helps in professional growth. Above all, it was the experiences of the stage that gave origin to the present study on Canine Perineal Hypospadia that was developed during the ESO period. Hypospadia is a rare congenital anomaly that occurs during fetal development resulting in malformation of the urethra and non-fusion of the ventral urethral sulcus. Hypospadia can be classified according to the location of its urethral opening. Together with this alteration, other anatomical alterations or associated pathologies may or may not occur. The objective of this study is to report a case of a 2 month old male SRD dog with severe perineal hypospadias, addressing the importance of imaging tests to clarify the clinical suspicions that emerged during the anamnesis and clinical examination. The animal is classified with severe perineal hypospadia, because along with this anomaly, there are other alterations like the penile malformation, not functionality of the organ and also the total opening of the foreskin. For this pathology, the surgical indication is total excision of the external genitalia and total amputation of the penis with orchiectomy. In addition to hypospadias, the animal presented ectopic testicles and anatomical alterations of some internal structures and organs, which could only be found after imaging. The surgical clinic added to the imaging diagnosis are important for the diagnosis of the patient and programming of the treatment and surgery of the animal in question.
