Urethral diverticulum in pregnancy: Rare case report and brief literature review.

Objective: Female urethral diverticulum (UD), an evagination of the urethral mucosa into the surrounding connective tissue, is extremely rare in pregnancy. No clear guidelines on the optimal management of UD have been established, except for a common conservative approach. Here, we discuss how to manage UD with pregnancy.
Case Report: A 39-year-old gravida 4, para 0, abortion 3 (G4P0A3) woman at 34 ⁺⁰ gestational weeks (GW) visited our outpatient department with a 6-cm septate vaginal mass. Transvaginal ultrasound sonography (TVUS) revealed a 5.5 x 4.9-cm multicystic mass, which was confirmed as UD with pelvic MRI. She was admitted because of preterm labor. A cesarean section was performed at 36 ⁺⁵  GW due to a previous myomectomy, and a healthy male baby was born. UD was still observed in the patient two months after delivery. Periurethral diverticulectomy was performed, and pathological analysis revealed UD with chronic inflammation and edema.
Conclusion: Previous reports and our case report show that UD can develop during pregnancy and that pelvic MRI is suitable for its accurate diagnosis. Vaginal delivery is possible in pregnant women with the small size of the UD. UD aspiration can permit vaginal delivery in a few cases; however, pus can occur at the aspirated site after the operation. If UD is still observed after delivery, urethral diverticulectomy is recommended.
