Open AccessA case of sacrococcygeal teratoma associated with antenatally acquired urethrovaginal fistula and hydrocolpos
Sacrococcygeal teratomas (SCTs) are known to cause urological complications, but urethrovaginal (UV) fistula as a complication of SCT is rare. We herein report a case of SCT with UV fistula and hydrocolpos.
