D.S.Schetkin. Successfully operated cloaca after gangrene of the external genital organs, perineum, part of the rectum and urinary bladder. (Medin. Review. 1893. No. 1)

In a 60-year-old woman, after extensive gangrene, the genitals represented next a picture: the large and small lips are absent, a small piece hangs from the left small lip. The defect resulting from gangrene is bordered by a scar, the remainder of the urinary bladder is directly adjacent to the rectal wall in the same place, where its integrity is broken.
