Acute urinary retention caused by a large hydrosalpinx.

Urinary retention is a rare condition in women. We report a case of intermittent retention associated with severe anterior displacement of the uterus and cervix caused by a large hydrosalpinx. We also highlight the possibility of a falsely elevated post-void residual as measured by a bladder scan due to hydrosalpinx. Resolution of the patient's symptoms was documented following salpingectomy.
