The resectoscope is a hysteroscope with a built in wire loop (or other shape device) that uses high-frequency electrical current to cut or coagulate tissue.  It was developed for surgery of the bladder and the male prostate over fifty years ago to allow surgery inside an organ without having to make an incision.

Like the standard hysteroscope, the resectoscope is inserted through the cervix.   It is larger in diameter than the diagnostic hysteroscope and requires dilation of the cervix.  Procedures using the resectoscope are almost always done in an operating room, such as in an outpatient surgery center.  Minor procedures can be done under local anesthesia, but most women prefer general anesthesia. 

The resectoscope is far more efficient at removing tissue (such as fibroids or large polyps) than conventional instruments.   Because it is so efficient, it should be used only by physicians who have training in its use and who use it on a regular basis.
