医源性隐睾的治疗

目的：探讨医源性隐睾的病因,预防和治疗特点。方法：回顾分析我院治疗的16例医源性隐睾患儿,其中睾丸鞘膜积液术后7例,腹股沟斜疝术后8例,尿道下裂术后1例。结果：16例均接受手术治疗,10例睾丸存在不同程度的萎缩,其中1例睾丸完全萎缩,行睾丸切除。术后随访12例,睾丸均在阴囊内,但发育较健侧差。结论：降低医源性隐睾发病率的根本措施是防止其发生,尽量减少不正确的医疗行为,并做到早期发现,早期行手术治疗。     

Acquired cryptorchidism is frequent in infancy and childhood

Accurate prevalence data for acquired cryptorchidism are currently sparse and systematic prospective studies have not yet been reported. Our aim was to determine the prevalence of testicular ascent in childhood. In a prospective longitudinal population-based child cohort from Copenhagen, Denmark (1997–2007), testicular position was examined according to a standardised protocol in a total of 1072 boys, at birth ( n  = 1051), at 3 months ( n  = 983), 18 months ( n  = 888), 36 months ( n  = 790) and again once between 4½ and 10 years of age ( n  = 509). Ascensus testis was defined as ascent of the testis into a cryptorchid position after normal scrotal position at birth. A congenital cryptorchid testis with spontaneous postnatal descent followed by recurrence of cryptorchidism was named recurrent cryptorchidism. Ascensus testis occurred in 0.2%, 0.6% and 0.6% of boys at 3, 18 and 36 months of age respectively. When including recurrent cryptorchidism the prevalence was 0.2%, 1.2% and 0.8% respectively. Ascensus testis accounts for 58% of all cases of cryptorchidism (congenital and acquired) at 18 months, 71% at 36 months and thereafter 69%. Ascensus testis accounts for more than half of cryptorchid testes seen in childhood and occurs in both previously scrotal and cryptorchid testes. We therefore recommend that all boys should have testis position checked regularly during childhood, at least up to 3 years of age.
