title: [Epidemiological and clinical aspects of visible urogenital malformations among adolescent's schoolboys at Cotonou].
abstract: OBJECTIVE
  To detect systematically visible urogenital malformations (VUGM) in adolescents and describe their epidemiological and clinical aspects.
  
  
  METHODS
  It was a cross sectional, descriptive and analytical study, conducted from February to August 2012. Upon 2724 adolescents from 10 to 19 years old, of the public secondary schools of Cotonou. Among the 26,594 registered pupils, 2724 were included and examined after a randomized sampling of 30 clusters.
  
  
  RESULTS
  The mean age of the pupils was of 15 ± 2.30 years (11-19 years), with a peak at 18 years. The prevalence of the VUGM was slightly higher (9.57%) in individuals those had parents with low socioeconomic level. The prevalence of the VUGM was high in Yoruba and related (P=0.02). It was stronger (9.84%) among subjects in puberty period's than in pre-puberty (6.69%) (P=0.03). From the 253 having VUGM, 78 (30.83%) had 146 functional signs. It was indexed 266 affections and of malformatives associations in 21 pupils (8.30%). Varicocele was the most frequent (5.47%), followed by inguinal hernia (0.99%), hydrocele (0.88%), anomalies of testis migration (0.59%), cyst of spermatic cord (0.51%), insulated testicular hypotrophy (0.48%), micro-penile (0.33%), hypospadias (0.22%), penile curvature (0.22%) and epididymis cyst (0.07%).
  
  
  CONCLUSIONS
  Among patients who had VUGM, the majority had at least a varicocele, which occupies so far the first place within these malformations at the adolescents in Cotonou.
