Neovaginal reconstruction is an important part of gender reassignment surgery.

We report a case of stone formation at the apex of vaginal vault constructed with sigmoid colon segment.

A 48-year-old woman presented with profuse vaginal discharge for 1 year. She had a history of gender reassignment surgery (male to female) in 1994, and the neovagina had been constructed with an isolated sigmoid colon.

Vaginoscopy performed using a cystoscope revealed multiple calculi at the vaginal vault on the endoscopic gastrointestinal anastomosis staples that had been used to close the vault.

Colon-vaginoplasty has the advantages of providing adequate lubrication, but excessive vaginal discharge could be a problem, as colon is a mucous membrane. Stone formation in the vaginal vault should be considered in cases of gender reassignment with persistent vaginal discharge.

This case also highlights the use of cystoscope in visualising the upper vagina in difficult circumstances.
