[The need for orchiopexy in the case of congenital undescended testis].

Congenital undescended testis (UDT) is a common congenital anomaly among males. Since ectopic position of the testis is considered a risk factor for the development of testicular cancer and infertility, early diagnosis and treatment are essential. Careful physical examination after birth should indicate those patients with UDT who must be followed up for possible orchiopexy at an early age. Treatment consists of performing orchiopexy at the age of 6-12 months to reduce the risk of malignancy and/or infertility. Despite the necessity of treating UDT, isolated cases of intra-abdominal seminoma are found. In patients with abdominal complaints and UDT, the possibility of problems due to this condition must be considered. In the present case, a patient with an intra-abdominal seminoma in the presence of unilateral UDT is presented.
