NCT02203318

Brief Summary

The aim of this study is to verify whether the hypertrophy of contralateral testis may predict the absence of the non-palpable testis in the boys younger than 24months of age. According to the previous studies of other countries, the large size of the contralateral testis of the nonpalpable testis has positive correlation woth the weak viability of the affected testis. We are going to evaluate this hypothesis with prospective study. 3 groups are going to be enrolled into this study ; non-palpable testis group(Group1), palpable but not normally descended testis group(group2) and control group(group3). The size of testis will be measured with Ultrasound and the length, width and the height will be measured before surgery at outpatient department. For the group 1 \& 2, the viability of the affected testis will be evaluated and compared after surgery. In addition the comparison with normal control group is also going th be conducted.

Outcome Measures

Primary Outcomes (1)

  • Size of contralateral testis

    The testicular size is measured 3-dimensionally with ultrasonography. The length, width and height will be measured and the volume of testis will be evaluated.

    1 day of initial visit

Study Arms (3)

control

healthy children with normal bilateral testis

undescended palpable testis

patient whose affected testis is not descended to the normal position but palpable and exist intact in the upper area

non-paplpable testis

patient whose affected testis is not palpable during the physical examination
