"「トイレの花子さん」症候群"の2例 : Nonneurogenic neurogenic bladder(Hinman症候群)の初期像?

Abstract

9歳女児, 7歳女児.「トイレの花子さん」というどこの学校にも存在するうわさ話・怪談の為にnonneurogenic neurogenic bladder(Hinman症候群)の初期像ともいえる臨床症状を示した症例を経験した

Two girls aged 6 and 7 years old with established urination habit complained of daytime incontinence and deterioration of nocturia after they started school life. They were quite afraid of the lavatory and sometimes skipped urination during school time completely. Voiding cystography revealed bladder trabeculation and vesicoureteral reflux. On cystometry, bladder compliance was preserved with no uninhibited contraction. Ghost tales about labatories, such as "the tale of Ghost Hanako, " prevail in almost every elementary school in Japan. In some children, especially schoolgirls, lavatory phobia results in dysfunctional voiding. Such "Ghost Hanako's syndrome" may be an early phase of non-neurogenic neurogenic bladder (the Hinman syndrome). Detailed information regarding school life and urination habit is important for the treatment of this entity.
