Primary anterior vaginal wall pure ammonium acid urate stone. Case report

Abstract

Vaginal stones are extremely rare and are classified as primary and secondary. A 45 year-old female presented with an unexplained dyspareunia and vaginal discomfort for 2 years unresponsive to traditional treatment. Vaginal examination revealed no prolapse or vaginal fistula. Digital examination revealed multiple small rounded firm to hard or tender masses varying in size from 0.5 to 1.5 cm anterior to the vagina. Patient was treated with midline anterior vaginal wall incision with the extraction of eight smooth surfaced stones with uneventful postoperative course. Stone analysis revealed that they were composed of pure ammonium acid urate (AU). We recommend that for any patient with unexplained dyspareunia or vaginal discomfort that has proved to be unresponsive to traditional treatment, the possibility of anterior vaginal wall stones should be kept in mind.
