Introduction: Male external genitourinary anomalies are common and important. Eearly diagnosis and treatment of the diseases can prevent late organic and psycho– economic complications.

Methods: The most simple way of diagnosis is a thorough physical examination. In this study we examined 4260 young male students (6-12 yrs old) from 16 primary schools in Tehan. Then the parents of the children with anomaly were asked about their history of anomalies.

Results: Anomalies were found in 156 (3.6%) students. The common anomalies were inguinal hernia in 80 cases (51.3%), unilateral undescended testis in 35 (22.3%). Hypospadiasis in 13 (8.3%), bilateral undescended testes in 4 (2.56%) and epispadiasis as well as chordoe in 3 (1.9%), respectively . In previous operated cases, 102 (66%) had emergent operation, 24% had been diagnosed by their physicans and 10% with their parents by chance.

Conclusion: According to easy availability of this system and complications of delayed management, it is recommended that routine physical examinations must be done.
