The main symptom of white vulvar lesions is unbearable itching of the vulva, which is intense regardless of the season and day and night, seriously affecting work and sleep. She had been suffering from white vulvar lesions for several years and urgently requested treatment as soon as possible because the itching was unbearable and she could not sleep at night. She had been treated with traditional medication, but to no avail. A few days ago, she heard from a friend who had also suffered from white vulvar lesions that focused ultrasound could treat white vulvar lesions, so she rushed here and registered for the treatment at 7:00 a.m. When the preoperative biopsy was performed for her, she told me how painful she was and how anxious she was that she could not be treated effectively in time. Focused ultrasound treatment of white vulvar lesions is a non-invasive treatment (or non-invasive treatment), which means that lesions deep in surface tissues are treated without surgical incision (excision) or destruction of surface tissues (skin, mucous membranes) and without going through puncture. It can focus the ultrasonic waves emitted outside the body through the surface tissues, in its specific deep lesion tissue (target area), in a short period of time the target area of the lesion tissue due to the absorption of energy and rapid warming, and produce a variety of biological effects, and finally make the lesion tissue damage denaturation, promote tissue reconstruction and microcirculation improvement and make the lesion tissue to recover. The cavitation effect produced by ultrasound can make the cell membrane lose continuity or make its permeability change, because the diseased or proliferating tissue is more sensitive to ultrasound, so the ultrasound in the specific energy range can selectively damage the diseased tissue cells and achieve the purpose of treatment.
