Abstract
Sixtyseven testes from 61 patients with an undescended testis treated in the past 11 years at our institution were examined Using intraoperative photographs or DVDs the area of the GN inside the processus vaginalis was measured and the ratio to that of the testis was determined When the GN was attached to the vas deferens the GN distance from the testis was also measured and the ratio to that of the transverse length of the testis deviation index was calculated Reference values were obtained from 23 testes from 15 patients with mobile testesIn cases with mobile testes the GN attached to the bottom of the testis and involved the lower pole of the epididymis Even though the GN was attached to the bottom of the testis in 43 testes in the UDT patients 64 the GN was found to be elongated The mean GN area ratio was 158 1SD 06 in the UDT cases in comparison to 047 02 in the cases with mobile testes The GN was attached to the vas deferens in 24 testes 36 The deviation index was 134 10 but the GN area ratio of these cases was 156 07 which was similar to that of the GN attached to the bottom of the testis
