RESUMO
Twenty -six cases of undescended testes were studied in a prospective way in a period from January 1998 to June1999. The age ranges between 2 months and 12 years with a mean of 4 years and a peak incidence of 4 years. The site of the undescended testis was right side in 14 cases, left sided in 6 cases and billateral in 6 cases. The clinically palpable testes were in 16 cases and impalpable in 10 cases. Associated hernia was present in 22 cases, and associated anomalies were present in one case as transverse [paradox] ectopia of the testis. Ultrasound diagnosis revealed positive testes in 22 cases and negative in 4 cases. The sonographer gave no inconclusive result. At exploration, testes were found in all cases except for 1 case, which proved to be anorchism. Out of the 22 positive cases of ultrasound all cases were recovered surgically. Out of the 4 cases of negative ultrasound, three were found at different locations and fixed in the scrotum. Fidelity of ultrasound diagnosis in this series proved to be 23 cases [22 positive and 1 negative] out of 26 with a score of 88.4%
