Macrosomic Infant of a Diabetic Mother with Hydrometrocolpos Presenting as Bladder Outlet Obstruction

Abstract

Infants of diabetic mothers (IDM) are at increased risk of congenital malformations due to the teratogenic effect of maternal hyperglycaemia.  Hydrometrocolpos, a developmental cystic dilatation of the uterus and vagina arising from the accumulation of cervical secretions and concomitant genital outflow tract obstruction is rare, occurring either in isolation or as part of recognised syndromes.

We report a case of hydrometrocolpos, an unreported condition in an IDM, presenting at birth as an intrabdominal mass manifesting as bladder outlet obstruction with secondary urinary tract infection to highlight its isolated occurrence in these high-risk infants that commonly present with systemic and other multiple congenital defects.
