Sigmoid Colonovaginoplasty – Case Series at the National Obstetric Fistula Center Katsina

Abstract

Mullerian duct abnormalities are rare and the exact incidence is unknown, patients may present with absence of the uterus, fallopian tubes, cervix and upper two third of the vagina, ovaries are usually present and functional. We treated 3 patients from 2020 to 2023, the average age was 23 years both presented with primary Amenorrhea, with well-developed secondary sexual characteristics, no cyclical abdominal pain or features of hyperandrogenism, and on examination they had normal external genitalia with short vagina or only a dimple. Radiological findings showed features of MRKH (present ovaries, absent or hypoplastic uterus, fallopian tubes and cervix). No renal abnormalities. A definitive repair with creation of a neovagina using the sigmoid colon segment was performed in a single stage which offers a promising and safe alternative for patients with MRKH.
