Transient Hydrocolpos due to Vesicovaginal Reflux

Abstract

Hydrocolpos is commonly due to obstructive causes such as imperforate hymen and vaginal septum. Transient hydrocolpos or non-obstructive hydrocolpos is an under-recognized entity due to a phenomenon called “vesicovaginal reflux” (VVR). It is commonly seen during voiding cystourethrography although it is not a familiar entity for radiologists. Failure to recognize VVR often leads to unnecessary higher imaging modalities. We report a case of young married woman who presented with daytime urinary continence and found to have transient hydrocolpos due to VVR.
