Pyocolpos is a rare complication of hydrocolpos. Hydrocolpos usually p
resents during adolescence and is associated with an imperforate hymen
. The following is a case of a 3-month-old girl with pyocolpos. Her hi
story was significant for a urinary tract infection (UTI) at 7 weeks o
f age. The authors believe that her UTI was caused by urinary retentio
n secondary to hydrocolpos. A complete evaluation may have prevented t
he complication of pyocolpos. Copyright (C) 1997 by W.B. Saunders Comp
