After hysteroscopy, it is sometimes necessary to remove abnormal tissues and uterine lesions using high-frequency electrical current. Gynecologists use a resectoscope for this purpose. This type of surgery is used to treat fibroids, septa, and other abnormal or excess tissues in the uterus.

As the term resectoscopy implies, the procedure is performed by visualizing the abnormal tissue and accessing it through the vaginal canal and cervix, during which the tissue is shaved and removed using electrocautery. This surgery is typically performed under spinal or general anesthesia. It can be carried out in either monopolar or bipolar modes, and each mode requires its specific resectoscope set.
