Utero-vaginal anastomosis in cases of cervical malformations: long-term follow-up and fertility challenges.

Purpose: To study the long-term results of utero-vaginal anastomosis in cases of cervical malformations.

Methods: This is a retrospective cohort study. Nine patients presented with cryptomenorrhea due to cervical malformations (5 patients with cervical agenesis and vaginal aplasia, 2 patients with cervical agenesis and upper vaginal aplasia, and two patients with cervical dysgenesis in form of cervical obstruction). Five patients had utero-vaginal anastomosis (UVA) with McIndoe vaginoplasty. Four patients had UVA without vaginoplasty. Follow-up was done by transabdominal and/or transvaginal ultrasound monthly for the first 3 months then every 6 months thereafter for a duration that ranged from 15 to 82 months. The main outcome measures are achieving menstruation, dysmenorrhea, pelvic inflammatory disease (PID), needed interventions after primary surgery, infertility, and pregnancy rate.

Results: Nine (100%) patients achieved menstruation, one (12%) experienced severe dysmenorrhea, two (22%) had PID, seven (78%) needed dilatation of the anastomosis site, three (33%) needed reoperation, nine (100%) had primary infertility, two (28.5%) achieved clinical pregnancy, and only one (14%) ended by live birth.

Conclusion: Conservative surgery for cervical malformation is a promising choice for relieving the obstructive symptoms. Regular dilatation is recommended. Pregnancy is a remote hope that is hindered by many challenges.
