女児尿道末梢部狭窄の2例

DISTAL URETHRAL STENOSIS IN GIRLS: REPORT OF TWO CASES

Ⅰ．緒言

　幼小児の排尿異常や尿感染症はともすると看過されやすいが，その基盤に何らかの重大な下部尿路の先天性異常が存在することが多い，先天性下部尿路通過障害としてはTrigonal curtain obstruc-tion, Bladder neck obstruction，後部尿道弁，外尿道口狭窄，Distal urethral stenosis等々が報告されている。

　このうち女児のDistal urethral stenosisは最近欧米において注目を集めているが，本邦ではまだその報告はないようである。

Two cases of stricture at the terminal portion of urethra which caused dysuria and urinary tract infection in little girls were reported.

Case 1 is a 7 years old girl with the chief complaint of terminal pain by micturition and lower abdominal mass. Past history reveals infrequent urination since infancy but for 1 month chief complaints were noticed and the lower abdominal mass was due to chronic urinary retention. Severe urinary tract infection, small and interrupting urinary stream which only dripped at the end of urination inspite of strain was present.
