Background: Labial fusion is a rare condition typically observed in prepubescent girls, but it can also occur in postmenopausal women due to estrogen deficiency. Methods: Our case report presents a unique instance of recurrent complete labial fusion causing bladder outlet obstruction in a postmenopausal woman. Results: The 84-year-old patient presented with dysuria and intermittent urine leakage. A physical examination revealed complete labial fusion with a small central opening. The diagnosis was confirmed through clinical evaluation, and surgical intervention was necessary to relieve the obstruction. Recurrent episodes followed despite a hormonal treatment with topical estrogen. Conclusions: This case highlights the importance of early diagnosis and the challenge of managing labial fusion in postmenopausal women, where recurrent episodes may complicate treatment. Surgical management, along with hormone therapy, remain essential for optimal outcomes. Further studies are needed to understand the recurrence mechanisms and to establish standardized treatment protocols.
