Abstract:
An infant was referred to our department with complaint of abnormality of the external genitalia. Hypospadias and right inguinal hernia were detected and left testis was palpable, but right testis was not palpable. Chromosomal examination revealed 45, X/46, X, idic (Y) (q11.2). On ultrasonographic examination, uterus and ovary were not recognized. At one year of age, we performed operation of right inguinal hernia and right cryptorchism. During operation right spermatic cord and epididymis were detected, but right testis was not detected. At two years of age, urethroplasty was performed. After the operation closure of hypospadias fistulas was performed. Now the patient does not have fistulas and has good clinical progress.
