[A case of labial adhesions with urinary retention]

A 69-year-old woman was admitted to our hospital complaining of urinary retention. On examination, the labia was found to be fused extensively, with a pinhole opening at the midline. The adhesions were separated under spinal anesthesia. One year after operation, there remains no recurrence. Etiological factor in labial adhesions are thought to include a combination of local inflammation and estrogen deficiency. In our case, the patient had hip joint disease. Hip joint disease is shown to influence the formation of adhesions by interfering with perineal hygiene and decreasing sexual activity.
