In brief
This retrospective study identifies preoperative factors that predict the need for vaginal replacement during primary cloacal malformation repair. Patients requiring urogenital separation with shorter vaginal length were significantly more likely to need vaginal replacement compared to those undergoing total urogenital mobilization.
Written by the GCMD Library team from the article.
Background
A subset of patients with cloacal malformations requires vaginal replacement during their primary reconstruction, increasing the surgical complexity. Identifying factors which predict the need for vaginal replacement would facilitate operative planning.
Methods
We retrospectively reviewed patients who underwent primary cloacal reconstruction at our Center (2014–2018) and assessed the length of the common channel, urethra, and vagina. The presence of hydrocolpos at birth, Müllerian anomalies, sacral ratio, and tethered cord were also assessed between patients who did and did not require vaginal replacement.
Results
50 patients were identified. 17/50 patients (34%) underwent a total urogenital mobilization (TUM), and none required vaginal replacement. 33/50 (66%) patients underwent a urogenital separation. 19/33 (58%) required vaginal replacement. This group had a shorter vagina (4.2 cm vs 6.6 cm, p
